Replacement procedures

Precautions

• Always wear an ESD wrist strap or ESD gloves when servicing the firewall.

• When removing FRUs (such as MPUs, interface modules, fan trays, power modules, and the CF

card):

{ Ensure good alignment with the slot and use uniform force to avoid damage to the FRUs.

{ Completely loosen each captive screw before removing FRUs to keep their panels in good

condition.

{ Hold a PCB by its edges. Do not touch any electronic components.

{ Put the removed FRUs on an antistatic workbench with the PCB side facing upward or place

them in antistatic bags.

Installing and removing a filler panel

Installed in empty slots on the firewall, filler panels can prevent dust from entering the firewall chassis.

Two types of filler panels are available for an F5000-A5 firewall:

• Filler panel for an MPU/interface module slot

• Filler panel for a power module slot
