Rear View - Watchguard NX3CE12 Hardware Manual

Rear View

The rear view of the XTM 1050 shows the AC receptacle, replaceable fans, replaceable and redundant power
supplies, and power switch.
Replaceable fans
The three fans decrease the internal temperature of the device. It is not necessary to power off the
XTM 1050 to replace a failed fan.
AC receptacles on each power supply
Each AC receptacle accepts a detachable AC power cord supplied with the XTM 1050. Each power
supply for the device is a WatchGuard standard auto-sensing AC power supply.
Replaceable power supply and power switch
There are two power supplies on the XTM 1050, each with their own power indicator light. The power
switch activates both power supplies. It is not necessary to turn off the XTM 1050 to replace a failed
power supply.
If one of the power supplies fails, the green power indicator light for that power supply goes out and
an audible alarm will sound.
Caution
Alarm reset button
If either of the two power supplies fail for any reason, an audible alarm will sound. Push the red reset
button to stop the audible alarm.
Hardware Guide
You must disconnect both power supplies before you remove the cover of the XTM 1050 for
any reason.
