Replacing Blades for Mediant 3000 HA

The procedure below describes how to replace a failed blade as well as an active,
operational blade for Mediant 3000 HA. Replacing an active blade is not common, but may
be required for future hardware upgrades.
Notes:
•
Do not use excessive force when inserting the blade into the chassis cage.
•
For replacing a failed blade, there is no need to perform a switchover to the standby
blade. In the event of a failed blade, the device automatically switches over to the
standby blade (making it the active blade). However, if you want to replace an active
blade (for whatever reason), you need to manually perform a switchover, as
described in this section.
•
Replace the failed blade as soon as possible to restore the HA mode.

To replace a blade in Mediant 3000 HA:
1. If you want to replace an active blade, do a manual switchover from the active to
standby blade as described in the User's Manual; otherwise, skip to Step 2:
2. Physically remove the failed blade from the chassis:
a. Using a Philips screwdriver, unfasten the screws located at both ends of the blade
that secure the blade to the chassis.
b. Press the blade's red ejector buttons on each of the two black ejector/injector
latches to release the blade from the slot.
c. Simultaneously rotate the ejector/injector latches outward in the horizontal plane
to disengage the blade from the slot.
d. Pull the two ejector/injector latches and gently slide the blade out of the slot.
3. Before you insert the new blade, verify that the software version installed on the new
blade is the same (or later) as the version currently installed on the active blade. For
example, if the version of the active blade is 6.4, the version of the new blade must be
6.4 or later.
4. Start the BootP Server utility and add a client with the new blade's MAC address and
define a private IP address for the new blade (must be in the same subnet as the
standby blade). For more information, refer to the User's Manual.
5. Insert the new blade into the chassis:
a. Choose the appropriate slot in the chassis.
b. Ensure that the blade's red ejector buttons on each of the two black
ejector/injector latches are pressed in (i.e., black ejector/injector latches in the
open, pulled out position).
c. Hold the blade horizontally and insert it into the slot, aligning its edges with the
groves inside the slot.
d. Ease the blade all the way into the slot, using your thumbs until the
ejector/injector latches touch the chassis and the blade is flush with the chassis
slot.
