Replacing Power Supplies
The Cisco CMX 3375 appliance can have one or two power supplies. When two power supplies are installed
they are redundant as 1+1.
Cisco Cisco CMX 3375 appliance ships with two power supplies. A replacement power supply can be obtained
from Cisco to replace a failed power supply.
Cisco CMX 3375 appliance also supports cold redundancy. Depending on the power being drawn by the
server, one power supply might actively provide all power to the system while the remaining power supply
is put into a standby state. For example, if you have two supplies connected to AC power, but the power
consumption can be satisfied by power supply 1, then power supply 2 is put into a standby state.

Replacing AC Power Supplies
Note
If you have ordered a server with power supply redundancy (two power supplies), you do not have to power
off the server to replace a power supply because they are redundant as 1+1.
Note
Do not mix power supply types or wattages in the server. Both power supplies must be identical.
