1.
If you are in the same physical location as the Acme Packet 4600 you can view
the graphic display on the front panel. The display will indicate the HA state. A
standby system displays (S) while an active system does not display (S).
2.
If you are not in the same physical location as the Acme Packet 4600, you can use
the ACLI show health command. The output of this command indicates the current
HA state of the Acme Packet 4600.
Once you have determined that the Acme Packet 4600 due for maintenance is in
standby state, you can continue with the appropriate procedures to replace a part.
If you need to perform maintenance on the active Acme Packet 4600 you need to
manually force the two Acme Packet 4600s to switch HA states. Forcing a switchover
renders the currently active Acme Packet 4600 in Standby state, and the current
standby Acme Packet 4600 will assume all traffic processing and forwarding as the
active system.
Note:
This procedure is only applicable to Acme Packet 4600 in an HA
deployment.
To force a Acme Packet 4600 into the standby HA state:
1.
Confirm that the relevant Acme Packet 4600 systems on active
and standby are synchronized with the show health command. Type
