When operating a pluggable module, such as a FIP module, memory module, CF card, or
HIM/MIM, follow these guidelines:
{
Ensure good alignment with the slot to avoid damage to the module during installation or
removal.

Before removing a module, make sure the captive screws are completely loosened.
Otherwise, the panel of the module may be deformed.

place them in antistatic bags.
Replacing a power module
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.
Use a Philips screwdriver to loosen the captive screws of the power module to be removed until
all spring pressure is released.
2.
Gently pull the power module out of the slot along the slide rails.

3.
Put the removed power module on an antistatic workbench or into an antistatic bag.

If you do not install a new power module in the slot, install a blank panel. To install a power
module, see “
