Chapter 2 Introduction
Congratulations on the purchase of the NETGEAR Prosafe Stackable Smart Switch. The Prosafe Smart Switch is a state-of-the-art, high-performance, IEEE-compliant network solution designed for users who require a large number of ports and want the power of Gigabit connectivity to eliminate bottlenecks, boost performance, and increase productivity. To simplify installation, the switch is shipped ready for use out of the box. This chapter serves as an introduction to the NETGEAR Prosafe Stackable Smart Switch and provides the following information: Overview Switch Features Package contents

Overview

This Installation Guide is for the following NETGEAR Prosafe Stackable Smart Switch models: FS728TSsupports 24 ports of 10/100 BASE-T, 2 ports of 10/100/1000 BASE-T, and 2 GbE combo (Copper/Fiber) ports FS752TSsupports 48 ports of 10/100 BASE-T, 2 ports of 10/100/1000 BASE-T, and 2 GbE combo (Copper/Fiber) ports FS752TPS PoEsupports 48 ports of 10/100 BASE-T, 2 ports of 10/100/1000 BASE-T, and 2 GbE combo (Copper/Fiber) ports. This model supports the added feature of Power over Ethernet (PoE).

These switches can be stacked together in a stack of up to six units, or a maximum of 192 10/100 ports, or can be used as stand-alone devices.
Introduction v1.0, December 2005
Using Gigabit ports, high-speed connections can be made to a server or network backbone. Application examples include: Connecting switches to each other with high-speed links Linking to high-speed servers Providing 10/100/1000 copper and fiber connectivity The 2 10/100/1000 Base T ports are primarily used for stacking, but can alternatively be used to provide additional bandwidth.
The NETGEAR Smart Switch also provides the benefit of administrative management with a complete package of features for the observation, configuration, and control of the network. With a Web-based Graphical User Interface (GUI), the switch's many capabilities can be viewed and used in a simple and intuitive manner. The switch's management features include configuration for port and switch information, VLAN for traffic control, port trunking for increased bandwidth, and Class of Service (CoS) for traffic prioritization. These features provide better understand and control of the network. Initial discovery of the switch on the network requires the Smart Wizard Discovery program, a utility that runs on a PC. The NETGEAR Smart Switch can be free-standing, or rack mounted in a wiring closet or equipment room. It is IEEE-compliant and offers low latency for high-speed networking. All ports can automatically negotiate to the highest speed. This capability makes the switch ideal for environments that have a mix of Ethernet, Fast Ethernet, or Gigabit Ethernet devices. In addition, all RJ-45 ports operate in half- or full-duplex mode, increasing the maximum bandwidth of each connection up to either 20 Mbps, 200 Mbps, or 2000 Mbps respectively. The maximum segment length is 328 feet (100 meters) over Category 5 Unshielded Twisted-Pair (UTP) cable, but much longer for fiber connections using SFP GBIC modules.

Introduction

Stacking Features

Stacking provides multiple switch management through a single point as if all stack masters are a single unit. All stack masters are accessed through a single IP address through which the stack is managed. The stack is can be managed from the following: Web-based Interface SNMP Management Station Devices support stacking up to six units per stack, or can operate as stand-alone units. Up to 192 10/100 ports are supported in a stack. During the Stacking setup, the switches will auto-select one as the Stacking Master. All other devices are named as slave stack members, and assigned a unique Unit ID. One of the slave units is designated as the backup master. The backup master acts as a slave stack master, but can become a stack master in the event of failure of stack master. The master and backup master are assigned unit IDs of 1 and 2. The Stack Master provides a Single point of control and management as well as a single interface in which to control and manage the stack. Switch software is downloaded separately for each stack members. However, all units in the stack must be running the same software version. A stack unit can operate in one of the following Modes: Stand-alonethe unit runs as a general switch and does not run the stacking application. Master Unitmanages the Stack and is responsible for the configuration. Master-Backupruns as a slave unit and monitors the operation of the stack master. If the master unit fails, you must select the Master-Backup manually to assume the Stack-master role. If a Master-Backup becomes the Master Unit, another Master-Backup will need to be selected manually. One of the Slave units will not automatically become a Master-Backup. Slaveruns a slave version of the Switching Algorithm, which allows the applications running on the master unit to control the resources of the slave unit.

2-12 v1.0, December 2005 Introduction
Device Hardware Interfaces
RJ-45 Ports RJ-45ports are auto-sensing ports. When inserting a cable into an RJ-45 port, the switch automatically ascertains the maximum speed (10 or 100 or 1000 Mbps) and duplex mode (half- or full-duplex) of the attached device. All ports support only unshielded twisted-pair (UTP) cable terminated with an 8-pin RJ-45 plug. To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink. This technology allows attaching devices to the RJ-45 ports with either straight-through or crossover cables. When inserting a cable into the switch's RJ-45 port, the switch automatically: Senses whether the cable is a straight-through or crossover cable. Determines whether the link to the attached device requires a "normal" connection (such as when connecting the port to a PC) or an "uplink" connection (such as when connecting the port to a router, switch, or hub). Configures the RJ-45 port to enable communications with the attached device, without requiring user intervention. In this way, the Auto Uplink technology compensates for setting uplink connections, while eliminating concern about whether to use crossover or straightthrough cables when attaching devices.

SFP GBIC Module The GBIC module bays accommodate standard SFP GBIC modules, such as the AGM731F, AGM732F, or AGM733 from NETGEAR, allowing fiber connections on the network. The module bay is a combo port, sharing a connection with an RJ-45 port. Being a combo port, only one type of connection can be active at any given time. For example, both copper and fiber port cannot be used at the same time. If both connectors are plugged in at the same time, the fiber port will be active. The SFP GBIC bay accommodates a standard SFP GBIC module.

Figure 3-1

Step 3: Checking the Installation
Before applying power check the following: 1. Inspect the equipment thoroughly. 2. Verify that all cables are installed correctly. 3. Check cable routing to make sure cables are not damaged or creating a safety hazard. 4. Ensure all equipment is mounted properly and securely.
Step 4: Connecting Devices to the Switch
The following procedure describes how to connect PCs to the switch's RJ-45 ports. The NETGEAR Smart Switch contains Auto Uplink technology, which allows the attaching of devices using either straight-through or crossover cables. Connect each PC to an RJ-45 network port on the Switch front panel, as shown in the diagram below. Use Category 5 (Cat5) unshielded twisted-pair (UTP) cable terminated with an RJ-45 connector to make these connections.

Figure 3-2

Note: Ethernet specifications limit the cable length between the switch and the attached device to 100 m (328 ft).

3-4 v1.0, December 2005

Step 5: Installing an SFP GBIC Module
The following procedure describes how to install an SFP Gigabit Ethernet module in the switch's Gigabit module bay. Standard SFP GBIC modules are sold separately from the Smart Switch. If an SFP GBIC module is not being installed at this time, skip this procedure. To install an SFP GBIC module: 1. Insert the SFP module into the SFP module bay.

Figure 3-3

2. Press firmly to ensure the module seats into the connector.
Step 6: Installing Device as Stand-alone or Stack Master
The device can operate as a stand-alone device, or part of a stack. By default the device is in stack mode. Changing the mode is possible through the switch's web page once the device has been booted and is operational. The default port for connecting the devices in a stack is the Gigabit copper port. The fiber port can also be used for stacking. Enabling the fiber port to be used for stacking, is through the switch's web page once the device has been booted and is operational.
There are two stacking topologies supported by the device, the Ring topology or Chain topology.

Figure 3-4

The device is Plug and Play in terms of stacking configuration. Before powering up the device, connect the devices into the required stacking topology. Power up the devices. The stacking Master and slave designations are configured through automatic discovery. Manually changing the stacking configuration is through switch's web page once the device has been booted and is operational. For more information on stacking see the NETGEAR Prosafe Stackable Smart Switch User Guide.

3-6 v1.0, December 2005

Step 7: Applying AC Power
NETGEAR Smart Switch does not have an ON/OFF switch. The method of applying or removing AC power is by connecting or disconnecting the power cord. Before connecting the power cord, select an AC outlet that is not controlled by a wall switch, which can turn off power to the switch. After selecting an appropriate outlet, use the following procedure to apply AC power. 1. Connect the female end of the supplied AC power adapter cable to the power receptacle on the back of the switch. 2. Connect the 3-pronged end of the AC power adapter cable to a grounded 3-pronged AC outlet. When applying power, the Power LED on the switch's front panel is Green. If the Power LED does not go on, check that the power cable is plugged in correctly and that the power source is good. If this does not resolve the problem, see Chapter 4, Troubleshooting.

Step 8: Switch Management through a Web Browser or the PC Utility for Initial Configuration
The NETGEAR Smart Switch contains software for viewing, changing, and monitoring the way it works. This management software is not required for the switch to work. The ports can be used without using the management software. However, the management software enables the setup of VLAN and Trunking features, and also improves the efficiency of the switch, which results in the improvement of its overall performance as well as the performance of the network. After powering up the switch for the first time, the Smart Switch can be configured using a Web browser or a utility program called Smart Wizard Discovery. For more information about managing the switch, see the Software Manual on the Smart Switch Resource CD.

This chapter provides information about troubleshooting the NETGEAR Smart Switch. Topics include the following: Troubleshooting chart Additional troubleshooting suggestions

Troubleshooting Chart

The following table lists symptoms, causes, and solutions of possible problems.
Table 4-1. Troubleshooting Chart
Symptom Power LED is off. Cause No power is received. Solution Check the power cord connections for the switch at the switch and the connected device. Ensure all cables used are correct and comply with Ethernet specifications. Check the crimp on the connectors and make sure that the plug is properly inserted and locked into the port at both the switch and the connecting device. Ensure all cables used are correct and comply with Ethernet specifications. See Appendix D. Check for a defective adapter card, cable, or port by testing them in an alternate environment where all products are functioning. Make sure the attached device is set to autonegotiate.
Link LED is off or intermittent.
Port connection is not working.
File transfer is slow or performance degradation is a problem. A segment or device is not recognized as part of the network.
Half- or full-duplex setting on the switch and the connected device are not the same. One or more devices are not properly connected, or cabling does not meet Ethernet guidelines.

Verify that the cabling is correct. Ensure all connectors are securely positioned in the required ports. Equipment may have been accidentally disconnected.
Troubleshooting v1.0, December 2005
Hardware Installation Guide for the Prosafe Stackable Smart Switch FS700TS Series Table 4-1. Troubleshooting Chart (continued)
Symptom ACT LED is flashing continuously on all connected ports and the network is disabled. A unit is linked to a stack, but does not join the stack. Cause A network loop (redundant path) has been created. Solution Break the loop by ensuring that there is only one path from any networked device to any other networked device. Remove the unit from the stack. If the stack links are copper links, push the "Restore to Default" button. If the stack links are combo links, use the Web Management to configure the unit as a stackable unit, with combo links used as the stacking ports.
The stacking ports of the new unit are configured differently from the stack, or the unit is configured as a stand-alone unit.
Additional Troubleshooting Suggestions
If the suggestions in Troubleshooting Chart do not resolve the problem, refer to the troubleshooting suggestions in this section.

Network Adapter Cards

Ensure the network adapter cards installed in the PCs are in working condition and the software driver has been installed.

Configuration

If problems occur after altering the network configuration, restore the original connections and determine the problem by implementing the new changes, one step at a time. Ensure that cable distances, repeater limits, and other physical aspects of the installation do not exceed the Ethernet limitations.

Switch Integrity

If required, verify the integrity of the switch by resetting the switch. To reset the switch, remove the AC power from the switch and then reapply AC power. If the problem continues, contact NETGEAR technical support. In North America, call 1-888-NETGEAR. If you are outside of North America, please refer to the support information card included with your product.

4-2 v1.0, December 2005

Troubleshooting

Auto-negotiation

The RJ-45 ports negotiate the correct duplex mode and speed if the device at the other end of the link supports auto negotiation. If the device does not support auto negotiation, the switch only determines the speed correctly and the duplex mode defaults to half-duplex. The gigabit port on the Gigabit module negotiates speed, duplex mode, and flow control, provided that the attached device supports auto-negotiation.

Case Study

NETGEAR Technology Boosts Productivity and Performance of Youth Charity
NETGEAR's stackable switches helped tackle JDRF's network traffic load performance problem by leaving sufficient free ports for expanding operations without persistent network downtime.
NETGEAR has contributed a vital increase in performance at a time when having to work around the network was simply not an option.

Profile

JDRF is the UK arm of a global charity dedicated to finding a cure for type 1 (juvenile) diabetes. JDRF pursues three main activities: fundraising through links with industry & commerce, supporting research into therapies & cures, and outreach to families & children with type 1 diabetes. Its UK operations are centred in London, with four branches around the country.

Background

JDRF, in common with almost every registered UK charity, tracks donations and events with a sector-specific database. As is often the case with databases in every sphere of business, this is a simple file-based system, remotely accessed via Citrix Metaframe by the branch offices. The JDRF donations base is immense, arising from a long-standing fundraising model using sponsored walks by teams developed by volunteer Walk Captains in the business community. This success has meant that central network performance is a critical factor for the entire organisation. Any liaison officer in any branch within the UK has to be able to find any donor record, in a matter of a few seconds. said Chris Askew, Director of Fundraising.

Problem/Objective

2006 has been a year of intense change for JDRF UK. The organisation has re-vamped its fundraising approach to include greater use of its existing, devoted supporter base within industry, the entertainment business, and families affected by diabetes. The progress of diabetes research in recent years has been accelerating: in particular, building on the completion of the human genome project, significant advances in stem cell research, and the development of successful islet transplantation techniques. This last advance is the biggest breakthrough in the field since the discovery of insulin in 1922. JDRF has responded to these developments by gearing up to deliver more funds to researchers. While the countrywide network was stable, an expansion of staff and activity in the head office was putting strain on an infrastructure last updated in 2003. Tracie Gardiner, Director of HR & ICT Operations, said: Peak loads on the national network tend to arise before each Walk Weekend, with every branch needing to run database queries and reports at the same time, leading up to the walks themselves. Increasing performance in the head office, managing network traffic loads between the three principal servers and avoiding bottlenecks was becoming a priority.

Solution

In co-operation with JDRFs IT advisory team from Dovetail Management Consultants (www.dove-tail.co.uk), JDRF selected NETGEARs new range of Smart Stackable Switches, in particular the FS728TS. The mix of Gigabit (1,000Mbps) and Fast (100Mbps) switch ports provided the solution to the expanding population in head office. What really made the difference is the smart stacking capability. NETGEARs FS728TS, and the larger FS752TS, have a unique edge for rapidly expanding small networks the Gbit ports at the right-hand end of the port panel daisy-chain together. This may not seem unique; until you watch the network integration specialist taking the last port in the daisy-chain stack and connecting it back to the top port on the top switch. The switches spot this arrangement and automatically use it to create a 4Gbps, fault-tolerant dual ring interconnect. We could see the speed advantage of the ring structure almost immediately, said Ruth Best, Data Quality Manager. Database searches used to be heavily impacted by email traffic, especially sending final layouts for walk materials to our external printer. With the ring in place, provided by the FS728TS in the server room, we can now run all our tasks as fast as the servers can operate. Traffic between member switches in the stack is routed automatically around the ring, taking the shortest path to its destination. With the FS728TS, the ring is the unique selling proposition, delivering throughput and tolerance traditionally reserved for networks with much larger budgets and much more time to tune and refine performance -sapping routing tables. Added features like Layer 3 prioritisation, optional Power over Ethernet capability and tight controls such as MAC address security per port and rate limits within the management interface, add to the overall appeal. We found another unexpected gain, comments Gardiner. Our building wiring was inherited from the previous tenant, and we never really got to the bottom of some of our workstation problems. The inbuilt line-testing features of the FS728TS allowed us to cut back on external contractor testing of all our installed plant, and only re-run the five cables that the FS728TS identified as below standard. Using the three FS728TS smart switches means that each server now has its own standard Gbit connection, and the 4Gbps ring makes every workstation perform like it is on the same backplane as the server it needs to talk to, while at the same time leaving sufficient free ports for future growth, and without persistent network downtime for updates or upgrades.

Business Impact/Result

JDRFs campaign is moving forward at a rapid pace due to medical advances in recent years, national concern, handling media requests and taking care of the special needs arising from being a children's charity. NETGEAR has contributed a vital increase in performance at a time when having to work around the network was simply not an option.
