Hardware replacement
CAUTION:
Wear an ESD-preventive wrist strap or ESD-preventive gloves for hardware maintenance. They are not
provided with the firewall. Prepare them yourself.
Replacing a power module
Before you replace a power module, power off the power module and remove the power cord.
The replacement procedure of an AC power module is the same as a DC power module. This section
takes an AC power module as an example.
To replace a power module:
1. Face the rear panel of the firewall
2. Use a Phillips screwdriver to loosen the captive screw of the power module.
3. Support the bottom of the power module with one hand, and grasp the handle with the other hand
to gently pull the power module out of the slot along the slide rails.

4. Put the removed power module on a workbench or into an antistatic bag.
5. If you do not install a new power module in the slot, install a filler panel. For information about
installing a power module, see " Installing a power module ."
Replacing an interface card
Because the interface card is not hot swappable, power off the firewall before you replace an interface
card.
To replace an interface card:
1. Use a Phillips screwdriver to loosen the captive screws of the interface card.
