4. Be sure that all equipment is mounted properly and secure ly.
Connecting to Power and Check the LEDs
The switch does no t have an On /Off switch. Th e o n ly way to apply or remove power is to connect
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 devices, a Gigabit Ethernet module, a console, or a combination of these to the
switch.
RJ-45 Ports
The switch uses Auto Uplink™ technology, which enables you to attach devices using either
straight-through or crossover cables. Use a Category 5 (Cat5) unshiel ded twisted-pair (UTP) cable
terminated with an RJ-45 connector.
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 “Connecting a Redundant Power Supply (RPS)” on page 2-6.
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).
Note: Ethernet specifications limit the cable length between the switch and the attached
device to 328 fe et (100 meters).

2-8 Hardware Installation
v1.0, July 2009
To connect a console to the switch:
1. Connect the null-modem cable to the console port on the rear of the switch.
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
operating 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:
•Installation Guide. Explains basic setup and configuration (provided as both a p rint docu ment
and in PDF format on the Resource CD).
•ProSafe 72 00R Ma naged S witches CLI R eference Manual. Gives detailed examples of how to
use the CLI, and is located on the Resource CD.
•ProSafe 7000 Series Managed Switch Administration Guide. Describes configuration
examples, and is located on the Resource CD.

Troubleshooting Chart
The following table lists symptoms, causes, and solutions of possible problems.
Table 3-1. Troubleshooting Chart
Problem Cause Solution
Power LED is off. No power is received Check the power cord connections for the
switch at the switch and the connected
device.
Make sure that all cables used are correct
and comply with Ethernet specifications.
Link LED is off or intermittent. Port connection is not
working. 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.
Make sure that all cables used are correct
and comply with Ethernet specifications.
See “Technical Specifications” in
Appendix A.
Check for a defective adapter card, cable,
or port by testing it in an alternate
environment where all products are
functioning.
File transfer is slow, or
performance degradation is a
problem.
Half or full duplex setting on
the switch and the connected
device are not the same.
Make sure that the attached device is set to
auto negotiate.
Check the system message log.

3-2 Troubleshooting
v1.0, July 2009
Additional Troubleshooting Suggestions
If the suggestions in Table 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 that
the software driver has been installed.
•Configuration
If problems occur after you chan ge the network configuration, restor e 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 auto
negotiation, the switch determines the speed, 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.
A segment or device is not
recognized as part of the
network.
One or more devices are not
properly connected, or cabling
does not meet Ethernet
guidelines.
Verify that the cabling is correct. Be sure
that all connectors are securely positioned
in the required ports. Equipment might have
been accidentally disconnected.
ACT LED is flashing
continuously on all connected
ports, and the network is
disabled.
A network loop (redundant
path) has been created. Break the loop by ensuring that there is only
one path from any networked device to any
other networked device.
