No power module is provided with the firewall. Purchase power modules as required. The installation
procedures for AC and DC power modules are similar. The following procedure installs an AC power
module.
To install a power module:
1.
To install the power module to slot PWR1, remove the filler panel from the slot. To install the
power module to slot PWR2, skip this step.
Figure2-6 Removing the filler panel
2.
Install the power module in a correct direction (with the power receptacle at right):
a.
Grasp the handle of the module with one hand and support the module bottom with the
other.
b.
Push the power module along the guide rails into the slot until it has firm contact with the
slot.

Installing a fan tray
CAUTION:
•
Before installation, make sure the airflow direction provided by the fan tray meets the
requirements for installation ventilation.
•
The device comes with both fan tray slots empty. To ensure good ventilation, you must install two
fan trays of the same model before powering on the device.
•
If a fan tray fails during operation, replace the fan tray as soon as possible and keep the failed fan
tray in place before replacing it.
•
To prevent damage to the fan tray and the connectors on the backplane, insert the fan tray gently.
If you encounter any resistance while inserting the fan tray, pull out the fan tray, re-orient it, and
then insert it again.
