Installing A Backup Msm; Verifying The Module Installation; Displaying Slot Status Information - Extreme Networks BlackDiamond 8806 Hardware Installation Manual

Installing Modules and Establishing Initial Management Access
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
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. Table 21
Use the command line interface (CLI)
information about the newly installed module.

Displaying Slot Status Information

Assuming the module has no problems, the command
of the slot where you installed the module) displays information about the module including: general
information about the module (name, serial number, part number), the state of the module (power
down, operational, mismatch between the slot configuration and the module in the slot), and the
number of ports on the module.
