Installing Mpus - H3C CR19000-20 Installation Manual

Installing MPUs

CAUTION:
• The router supports active/standby MPU switchover when you install two MPUs for the router.
For the standby MPU to start up correctly, make sure the active and standby MPUs are the same
model.
• When you install an MPU, avoid damaging the connectors on the MPU.
• To prevent a filler panel from being drawn into the chassis when fan speed is high, use both
hands to grasp the filler panel by its two sides during filler panel installation and removal on an
operating router.
• If you are not to install an MPU in an MPU slot, keep the filler panel in the slot.
The router has two MPU slots. You can install one MPU, or two MPUs in 1+1 redundancy for the
router.
To install an MPU:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Remove the filler panel from the target MPU slot.
Keep the removed filler panel secure for future use.

3. Orient the MPU correctly and align the MPU with the slot. Insert the MPU into the slot and fully
open the ejector levers on the MPU.
