Connecting and Disconnecting Cables on the 8900-G96T-c Module
The ports on the 8900-G96T-c module use MRJ21 connectors. To connect these ports:
1 Align the cable connector with the port connector and firmly press the cable connector into place.
2 Use a small straight-tip screwdriver to align and tighten the retaining screw at each end of the cable
connector.
Installing a Backup MSM
If you install a backup MSM, use the synchronize command to replicate all saved images and
configurations from the primary MSM to the backup MSM.
You are not prompted to synchronize the images and the configurations from the primary to the
backup. If not synchronized, the backup uses its image and the primary configuration. This image/
configuration mismatch will likely cause the switch to operate differently after failover.
Caution
Depending on the size and complexity of your network, you should install and configure a
backup MSM when network disruption will be minimal. You may need to reboot your switch
after you use the synchronize command.
Verifying the Module Installation
After you install a module, verify that it is working correctly by checking the LEDs on the front panel of
the module.
The following table
shows normal LED operation for correctly installed MSMs and I/O
modules.
