Power and cooling problems

If the power LED does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or
internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses, or
surges at the power outlet, and verify that the fans on the unit are unobstructed and running prior to shutdown. You can also check
whether fans are obstructed using the show chassis CLI command.
If the device is continuously rebooting, check the temperature of the system. If you have dual power supplies installed, be sure that they
match. DC and AC power supplies installed in the same unit will cause continuous rebooting.
If you still cannot isolate the problem, the internal power supply may be defective. In this case, contact Technical Support for assistance.

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 switch from anywhere within the attached network using Telnet, SSH, or other network
management software. However, you must first configure the switch 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 port through which you are connecting to the switch has not been disabled. If it has not
been disabled, then check the network cabling that runs between your remote location and the switch.

the condition. If the condition persists,
contact Technical Support.
• Verify that the switch and attached
device are powered on.
• Be sure the cable is plugged into both
the switch and the corresponding
device.

used and its length does not exceed
specified limits.

device and cable connections for
possible defects. Replace the
defective adapter or cable if
necessary.
