Replacing the VC Flex-10 module
CAUTION: Be sure to update the firmware on the new VC Flex-10 module. This operation will
take the volumes offline.
IMPORTANT: Clients will lose connectivity during this procedure unless using a bonded network.
If not using a bonded network, clients should be disconnected before starting the procedure. In
addition, both externally facing uplinks must be connected to your external network. If uplinks are
not connected to the external network, connectivity will be lost when one of the Flex-10 switches
goes offline during a firmware update.
To replace a VC Flex-10 module:
1. Disconnect the network connections into the VC Flex-10 module (bay 1 or 2).
2. Remove the VC Flex-10 module.
3. Replace the VC Flex-10 module.
4. Reconnect the cables that were disconnected in Step 1 to their original ports.
5. Restore the configuration settings.
For more information, see “Backing up HP P4800 G2 solution configurations” (page 11).
