Replacement procedures

The router uses a modular, all-pluggable design, and supports replacing hot swappable modules
without interrupting the router operation.

Safety recommendations

1. Always wear an ESD wrist strap or ESD gloves when replacing the modules.
2. When working with a removable module, such as an MPU, RPE-X1/RPE-X3/RPE-X5/RPE-X5E
carrier (used when you use an RPE-X1/RPE-X3/RPE-X5/RPE-X5E MPU), FIP module, SAP
module, switching fabric 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 might be deformed.
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 procedure of an AC power supply is the same as a DC power supply. This section
takes an AC power supply as an example.
To replace a power supply:
1. Loosen the captive screws of the power supply until all spring pressure is released.
2. Gently pull the power supply out of the slot along the slide rails.

3. Put the removed power supply on an antistatic workbench or into an antistatic bag.
4. If you do not install a new power supply in the slot, install a filler panel. To install a power supply,
see "Installing a power supply."
