Power Supply Module

The Secure Firewall 4200 supports two AC power supply modules so that dual power supply redundancy
protection is available. Facing the back of the chassis, the power supply modules are numbered left to
right—PSU-1 and PSU-2.
The power supply module is hot-swappable.
Note
Attention
AC Power Supply
The dual power supplies can supply up to 1900-W power across the input voltage range. The load is shared
when both power supply modules are plugged in and running at the same time.
Note
Six network activity LEDs:
• Amber—No connection, or port is not in
use, or no link or network failure.
• Green—Link up, no network activity.
• Green, flashing—Network activity.

After removing power from the chassis by unplugging the power cord, wait at least 10 seconds before turning
power back ON. You want to keep the system power off, including the standby power, for 10 seconds.
Make sure that one power supply module is always active.
The system does not consume more than the capacity of one power supply module, so it always operates in
full redundancy mode when two power supply modules are installed.
