Floor model
The management system card is at the top front of
the case. At its center is a DB-9 serial RS-232
port, a connection for setup, monitoring and
upgrade of the unit from any computer system
with an RS-232 interface. The optional 10/100
BaseT Ethernet management services card
enables Telnet-based monitoring and
management. It also provides the ability to update
the firmware in the array via FTP.

sled contains two hard drives. Up to 24 hard
drives may be installed on the 12 sleds. Empty
bays should be covered by blank faceplates or
empty sleds. Access is provided by loosening two
screws and gently pulling on the sled handle.

Between the power supplies and blower
assemblies are two slots that hold the Host
Interface Cards. The HIC is the connection point
into the array and is available in three options: 1-
Gigabit Fibre Channel, 2-Gigabit Fibre Channel,
or Ultra 160 SCSI. Host Interface Cards have fault
and on-line or fault and activity LED indicators,
depending on the model.

SCSI
The SCSI card faceplate has a rotary
binary-coded hex switch to set the SCSI ID of the
array. The SCSI card also has an in channel, to
connect via cable to the unit’s communication
source, and an out channel, available for daisy-
chaining arrays together or to complete
termination using an external LVD terminator.
