In-Band Access
You can access the management agent in the switch from anywhere within the attached
network using Telnet, a Web browser, or other network management software tools.
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.
Replacing the Power Supply
CAUTION
•
When installing a new PSU, make sure it has the same airflow direction as
the fan modules and the other power supply.
•
For switches that only using a single power supply, removing the power
supply will cause the switch to automatically shutdown.
The PSUs can be replaced without the use of special tools. Before replacing any of the
PSUs, verify the status of the PSU to determine if there is a need for replacement.
NOTE:
•
In the event of a power supply failure, you can replace the defective unit without
powering down the system, provided that there is at least one power supply must
connect to a power source.
To replace the power supply unit, do the following:
1
Disconnect the AC power cord of the PSU that you want to remove.
2
Press the plug retainer and then pull the handle to slide the PSU away from the
chassis.
NOTE:
•
Take note of the part number of the removed PSU.
•
When making order for replacement modules, make sure that the part number of the
new PSU is the same as the part number of the removed PSU.
3
Ensure the power supply unit is correctly oriented, then install the new PSU into the
chassis until it is firmly seated.
4
Connect the AC power cord to power on the switch.
