PFC 500/E Instruction Manual
2 December 1999
The front panel contains the chassis address (CA) light, two status lights for each disk
module slot, and two status lights. All lights are visible with the front door closed.
The chassis address light displays the chassis address setting for the PFC500. The
PFC500 must have an CA of 0. You must set that CA using the chassis address
switches, as explained in Chapter 2.
The status lights are described in the “Monitoring PFC 500/E status” on page 40.
Midplane
The midplane distributes power and signals to all the chassis components. All CRUs
except the fan packs plug directly into midplane connectors.
