Protecting Against Electrostatic Discharge
Warning: Static electricity can harm delicate components inside your system. To
prevent static damage, discharge static electricity from your body before you
touch any of the electronic components, such as the microprocessor. You can
do so by periodically touching an unpainted metal surface on the switch.
You can also take the following steps to preve
nt damage from electrostatic discharge (ESD):
1. When unpacking a static-sensitive component from
its shipping carton, leave it in the antistatic
package until you are ready to install it. Just before unwrapping the antistatic package,
discharge static electricity from your body.
2. Before moving a sensitive component, place
it in an antistatic container or package.
3. Handle all sensitive components in a static
-safe area. If possible, use antistatic floor pads,
workbench pads, and an antistatic grounding strap.
Unpacking the Hardware
Check the contents of the boxes to make sure that all items are present before beginning the
installation.
1. Place the container on a clean flat surface, and c
ut all straps securing the container.

or disconnect the power cord. Before you connect the power cord, select an AC outlet that is not
controlled by a wall switch (which can turn off power to the switch).
After you select an appropriate outlet, follow these steps to apply AC power:
1. Connect one end of the AC power adapter cable to the rear of the switch, and the other end to
a grounded three-pronged AC outlet.
2. Check the Power LED on the front panel of the switch. The LED should light up in the
following sequence:
• The LED turns yellow as the switch runs a power-on self-test (POST).
• If the switch passes the test, the LED turns green. The switch is working and ready to pass
data.
• If the POST fails, the Power LED blinks yellow.
If the Power LED does not light up, check that the power cable is plugged in correctly and that
the power source is good. For help with troubleshooting, see
Chapter 3, “Troubleshooting.

You can connect an external DC-to-DC power supply unit to the switch to provide redundant
power in case the primary power supply fails. To connect a redundant power supply (RPS) unit to
the switch, first turn off the switch. When the power is off, you can remove the cover plate and
connect the RPS unit to the switch. After all connections are completed, apply power to the switch.
If you would like to purchase a RPS unit that is compat
ible with this switch, go to the NETGEAR
product support website http://www.kbserver.com. Select your product in the Product Support
section of the screen. When the product support screen di
splays, look for the Certified RPS Power
Supplier link.
Stacking
You can connect up to eight switches to form a stack with a single management IP address. The
switches automatically select a master unit. Once the master is selected, you can use its console to
manage all the switches in the stack.
Two stacking port can be used for stacking, while the remaining two I/O module bays can be used
for
10-Gigabit Ethernet uplinks.
To set up a stack:
1. Co
nnect the provided stacking cable from one switch’s IN stacking port to another switc h ’s
OUT stacking port.

v1.0, October 2008
3. Connect each switch to the next in a cascade to build the backplane of the stack. Finally,
connect the last switch in the stack to the first switch, to close the ring and provide redun dancy
and resiliency to the stack.
The switches automatically select the master switch
in the stack.
4. To use the console and Command Line Interface (CLI), use a se
rial cable to connect the
console to the master switch. This single console connection lets you manage all the switches
in the stack.
For information about working with the CLI, see the Com
mand Line Interface Reference for the
ProSafe 7200RS Series Layer-2 Stackable Switches on the Resource CD that shipped with your
product.
Connecting Equipment to the Switch
You can connect devices, a Gigabit Ethernet module, and/or a console to the switch.
RJ-45 Ports
The switch uses Auto Uplink technology, which enab le s you to attach devices using either
straight-through or crossover cables. Use a Category 5 (Cat5) unshielded twisted-pair (UTP) cable
terminated with an RJ-45 connector.
Note: Ethernet specifications limit the cable length between the switch and the attached
device to 328 feet (100 meters).
Connecting a Console to the Switch
After you install the switch and apply power, you can connect to it with a terminal or workstation.
You can use the Command Line Interface (CLI) to identify the IP address. If you are stacking
switches, see “Stacking” on page 2-7.
To use a console you need the following items:
• VT100/ANSI terminal, or a Windows PC, Apple Macintosh PC, or UNIX workstation.
• Null-modem cable with 9-pin connectors on
each end (shipped with the product).
To connect a console to the
switch:

1. Connect the null-modem cable to the console port on the rear of the switch.
Console port
Figure 2-5
2. Connect the other end of the cable to a workstation or terminal.
3. If you attached a workstation, start a terminal-emulation
program.
• Microsoft Windows users can use HyperTerminal, which comes with the Windows
opera
ting systems.
• Macintosh users can use ZTerm.
• UNIX users can use a terminal emulator such as TIP.
4. Configure the terminal-emulation program
to use the following settings:
• Baud rate: 9,600 bps
• Data bits: 8
• Parity: none
•Stop bit: 1
• Flow control: none
After you connect a console to the switch,
you will need to configure the switch. The following
documents are provided for this purpose:
• Co
mmand Line Interface Reference for the ProSafe 7200RS Series Layer-2 Stackable
Switches: Gives detailed examples of how to use the CLI, and is located on the Resource CD.
• NETGEAR 7
000 Series Managed Switch Administration Guide: Describes configuration tasks,
and is located on the Resource CD.

3-2 Troubleshooting
v1.0, October 2008
Additional Troubleshooting Suggestions
If the suggestions in Table 3-1 on page 3-1 do not resolve your problem, refer to the
troubleshooting suggestions in this section.
• Network Adapter Cards
Make sure that the network adapter cards installed in the PCs are in working condition and the
software driver has been installed.
• Configuration
If problems occur after you change the network configuration, restore the original
connections. Then find the problem by making the changes, one step at a time. Make sure that
cable distances, repeater limits, and other physical aspects of the installation do not exceed the
Ethernet limitations.
• Switch Integrity
You can verify the integrity of the switch by resetting the switch. To reset the switch, use the
Tools> Reset command or remove AC power from the switch and then reapply AC power. If
the problem continues, contact NETGEAR technical support.
• Auto-Negotiation
The copper 10/100/1000 Mbps 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 autonegotiation, the switch only determines the speed correctly and the duplex mode defaults to
half-duplex. The fiber gigabit ports negotiate speed, duplex mode, and flow control, provided
that the attached device supports auto-negotiation.
