(storage bays)
Each slot in a bay can contain one hot-pluggable 3.5-inch disk
drive.
The slots are numbered 1 – 6 left to right (numbers are not
SCSI IDs). SCSI IDs are 0, 1, and 2 for each group of three
disk drives. The drives are mirrored as follows: 1 – 4, 2 – 5,
and 3 – 6. Each drive has two status LEDs. Refer to Table 1-2
for information on disk drive status LED panel indicators.
I
– CPU modules
Two CPU modules providing Dual Modular Redundancy
(DMR). The CPU modules are numbered 1 – 2 left to right.
Each CPU module contains one or two processors and a
maximum of up to 2 GB of SDRAM memory. Refer to Table
1-3 for information on CPU module status LED indicators.
J
– PCI modules with PCI adapters
Two hot-pluggable PCI modules. The PCI modules are
numbered 1 – 2 left to right. Each PCI module contains four
PCI adapter card slots and two embedded adapters (LAN and
SCSI disk). Each module has a pair of status LEDs and a
LAN port. See Table 1-4 for a list and description of the PCI
module status LED indicators. See Table 1-5 for a list and
description of the PCI adapter-slot status LEDs.
K –
Device module
Houses an IDE 24X CD-ROM drive and 3.5-inch IDE high-
capacity (120 MB) super (floppy) disk drive (not hot
pluggable).
L –
