When rack mounting the wireless controller, pay particular attention to the
following factors:
◆
Rack Types: You can use any standard EIA 19-inch equipment rack with either
two or four posts. The bracket hole pattern should be spaced 1U (1.75 in. or
4.45 cm) apart.
◆
Rack Stability: Whenever possible, secure the rack to the building ceiling or
floor, particularly if you are located in a region where earthquakes are common.
◆
Rack Planning: When installing equipment in a rack, first plan how units can
be best arranged. Try to always mount the heaviest equipment at the bottom
of the rack.
◆
Temperature: Since the temperature within a rack assembly may be higher
than the ambient room temperature, check that the rack-environment
temperature is within the specified operating temperature range. See “Unit
Cooling Requirements” on page 22.
◆
Mechanical Loading: Do not place any equipment on top of a rack-mounted
unit.
◆
Circuit Overloading: Be sure that the supply circuit to the rack assembly is not
overloaded.
◆
Grounding: Rack-mounted equipment should be properly grounded.

flow is insufficient, it may cause the wireless controller to overheat and possibly fail.
Rack Cooling When mounting the wireless controller in an enclosed rack or cabinet, be sure to
check the following guidelines to prevent overheating:
◆
Make sure that enough cool air can flow into the enclosure for the equipment it
contains.
◆
Check that the rack or cabinet allows the hot air to exit the enclosure (normally
from the top) without circulating back into equipment.
◆
If the enclosure has sides or doors with ventilation holes, make sure they are
not blocked by cables or other obstructions.
◆
Route cables within the rack or cabinet to maximize the air flow.
◆
When possible, do not completely fill the rack or cabinet with equipment, allow
some unused space within the enclosure for better air flow.

1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX connections should also
work for 1000BASE-T, providing that all four wire pairs are connected. However, it is
recommended that for all critical connections, or any new cable installations,
Category 5e (enhanced Category 5) or Category 6 cable should be used. The
Category 5e and 6 specifications include test parameters that are only
recommendations for Category 5. Therefore, the first step in preparing existing
Category 5 cabling for running 1000BASE-T is a simple test of the cable installation
to be sure that it complies with the IEEE 802.3-2008 standards.
Connection Procedure Follow these steps to connect cables to RJ-45 twisted-pair copper ports.
1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.

The system is not receiving power.
How to Connect to the Console Port
The RJ-45 Console port on the wireless controller’s front panel is used to connect to
the unit for out-of-band console configuration. The console device can be a PC or
workstation running a VT-100 terminal emulator, or a VT-100 terminal. An RJ-45-toDB-9 cable is supplied with the wireless controller for connecting to a PC’s RS-232
serial DB-9 DTE (COM) port.
Note: To connect to notebooks or other PCs that do not have a DB-9 COM port, use
a USB to male DB-9 adapter cable (not included with the wireless controller).

Check connections between the PSU, the power cord and the wall
outlet.
Contact your dealer for assistance.
Power cycle the switch to try and clear the condition.
If the condition does not clear, contact your dealer for assistance.
Verify that the switch and attached device are powered on.
Be sure the cable is plugged into both the switch and
corresponding device.
Verify that the proper cable type is used and its length does not
exceed specified limits.
Check the attached device and cable connections for possible
defects. Replace the defective cable if necessary.
System Self-Diagnostic Test Failure
If the Pwr/Sys LED indicates a failure of the system power-on-self-test (POST), you
can use a console connection to view the POST results. The POST results may
indicate a failed component or help troubleshoot the problem. For more
information on connecting to the console port and using the CLI, refer to the CLI
Reference Guide.
Note a POST failure normally indicates a serious hardware fault that cannot be
rectified or worked around. If you encounter a POST failure, you should contact
your dealer for assistance.

Power and Cooling Problems
Power and Cooling Problems
If the power indicator does not turn on when the power cord is plugged in, you
may have a problem with the power outlet, power cord, or power supply unit.
However, if the unit powers off after running for a while, check for loose power
connections, power losses or surges at the power outlet. If you still cannot isolate
the problem, the power supply unit may be defective.
Installation
Verify that all system components have been properly installed. If one or more
components appear to be malfunctioning (such as the power cord or network
cabling), test them in an alternate environment where you are sure that all the
other components are functioning properly.
In-Band Access
You can access the management agent in the wireless controller through a
connection to any port using Telnet, a web browser, or other network management
software tools. However, you must first configure the wireless controller with a valid
IP address, subnet mask, and default gateway. If you have trouble establishing a
link to the management agent, check to see if you have a valid network connection.
Then verify that you entered the correct IP address. Also, be sure the wireless
controller port has not been disabled. If it has not been disabled, then check the
network cabling that runs between your remote location and the wireless
controller.
