Replacement procedures
The router uses modular design. All modules for the router are hot swappable.
Safety recommendations
•
Always wear an ESD wrist strap or ESD gloves when you replace the modules.
•
To hot swap an LPU or HIM/MIM, first use the
remove
command to stop the card from
operating.
•
When you replace FRUs, such as MPUs, LPUs, memory modules, the CF card, and
HIMs/MIMs, follow these guidelines:
{
Ensure good alignment with the slot to avoid damage to the module during installation or
removal.
{
To prevent module panel deformation, make sure the captive screws are completely
loosened before removing a module.
{
Avoid touching any components on the PCB during observing or moving the module.
{
Put the removed module on an antistatic workbench with the PCB side facing upward or
place them in antistatic bags.
Replacing a power supply
The replacement procedures for an AC power supply and a DC power supply are the same. This
section uses an AC power supply as an example.
To replace a power supply:
1.
Face the front of the router and locate the power supply to be removed.
2.
Use a Phillips screwdriver to completely loosen the captive screws of the power supply.
3.
Holding the handle of the power supply with one hand and supporting the bottom of the power
supply with the other hand, gently pull the power supply out of the slot along the slide rails.
Put the removed power supply on an antistatic workbench or into an antistatic bag.

4.
Install a new power supply. For the installation procedure, see "

If you do not install a new power supply in the slot, install a filler panel.
Replacing an MPU and a switching fabric module
Prerequisites
•
If the router is installed with only one MPU, make sure all power sources to the router are turned
off before replacing the MPU.
