Installing an MPU/LPU
The pink edged MPU slots and purple edged LPU slots of a 11908-V switch are located at the front panel.
The MPUs and LPUs are vertically oriented. When installing an MPU or LPU, make sure its PCB faces left.
To install an MPU or LPU:
1. Wear an ESD wrist strap, and make sure it makes good skin contact and is well grounded. For
more information, see "Attaching an ESD wrist strap."
2. As shown in
callout 1 on Figure 17, rem
