Note:
Always try to first reboot the Acme Packet 1100 from the ACLI before performing a
cold reset. Only reset the system as a last resort.
To reset the Acme Packet 1100:
1.
Insert a rigid paperclip-sized tool into the small hole on the rear of the chassis as indicated
in the following graphic. The system immediately resets and begins its initialization and
boot sequence.

Power Cycling
Power cycling the system is the process of turning the chassis off and then on by first
unplugging from and plugging in to the AC power cord to the power supply. It is imperative
that you wait at least 10 seconds between power down and power up to ensure that all
components are completely powered down before restart.
Note:
Power cycling the Acme Packet 1100 without performing a halt operation can lead to
data loss to the storage device. To ensure stable operation, a file system check is
performed upon the next power up. This check may take several minutes to complete,
and should not be interrupted.
Forcing Switchover for HA Nodes
When performing hardware maintenance on the Acme Packet 1100, it is best to minimize any
risk of interrupting network traffic or losing data. If the Acme Packet 1100 is configured as an
HA node, only work on the Acme Packet 1100 that is in standby mode.
To determine the HA state of each Acme Packet 1100 in an HA pair, review the HA LED on
the front panel or use the ACLI
show health
command. Once the Acme Packet 1100 due for
maintenance is in standby mode, continue with the appropriate procedures to service it.
To perform maintenance on the active Acme Packet 1100, manually force the two Acme Packet
1100s to switch HA states. Performing a switchover forces the currently active Acme Packet
1100 to standby mode while the current standby Acme Packet 1100 will become the active
system, assuming all traffic processing and forwarding.
