If the slot is to remain empty, install a blank faceplate to ensure proper airflow and to keep dust out of the chassis;
otherwise, install another power supply module.
Step 5 To replace a power supply module, hold the power supply module with both hands and slide it into the power supply
module bay.
Step 6 Push in the power supply module gently until you hear the latch engage and it is seated.
Step 7 Plug in the power supply cable.
Step 8 Check the LED on the power supply to make sure the power supply is operative. See Power Supply Modules.
Connect the DC Power Supply Module
For the Firepower 2130 and 2140, the input connector and plug must be UL-recognized under UL 486 for
field wiring. The connection polarity is from left to right: negative (–), positive (+), and ground.
Use the handle on the power supply for installation and removal. You must support the module with one hand
because of its length.
