LED Signals
No LEDs are provided on the controller board; however,
the following LED signals drive LEDs on the controller face
plate: Host Activity, Device Activity, Not Active (Amber),
Active (Green), Cache Dirty, Manufacturing Diags On and

Memory Controller/
Hardware XOR
Engine
The FC2500 RAID Controller uses an ASCI for cache data
transfer, RAID XOR functional control, and other propri-
etary functions.
Fibre Channel
Three device ISPs each provide a 1GHz/sec FC_AL class 3
interface. These interfaces adhere to the Fibre Channel
Arbitrated Loop Direct Disk Attach Profile. One host ISP
supports full duplex, F-ports, IP, Class 2 and Multiple Target
IDs (MTIDs); the two remaining ISPs provide the disk inter-
faces.
Controller Board
Connectors
The controller board has two 72-pin edge connectors: one
at the front and one at the rear of the board. The connectors
provide electrical connection to three fibre channels (one
host and two device), loop enable signals, multi-purpose
jumper signals, activity and status LED signals, RS232
signals, and the board power and ground signals.
Power Conversion
The FC2500 RAID Controller operates on +5V input
power and internally co5V to 3.3V as needed. Input
power requirements conform to the SFF power limit.
