Replacement procedures
Precautions
• Always wear an ESD-preventive wrist strap or ESD-preventive gloves when servicing the firewall.
• When removing FRUs (such as the CF card and interface modules):
{
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.
Replacing an interface module
IMPORTANT:
Interface modules are hot-swappable.
The methods for replacing interface modules are similar. This example replaces an 8GBE interface
module.
To replace an interface module:
1. Face the rear panel of the firewall and locate the interface module to remove.
2. Loosen the captive screws on the interface module with a Phillips screwdriver until all pressure is
released.
Figure 50 Loosening the captive screws
3. Pull the two ejector levers at both ends of the interface module outward to release the interface
module, and then gently pull the interface module out along the slide rails.
Put the removed interface module in an antistatic bag.
