3 Getting Started with the Subsystem
3.1 Connecting the RAID Subsystem to the Host
This section describes how to connect the EP-2126-SA3 to your host system.
The subsystem supports Ultra 320 SCSI LVD interface which provides fast 320MB/s
data transfer rates using a 16-bit SCSI bus. Installation of the disk array is very similar
to the installation of a standard SCSI drive. The SCSI connector accepts the standard
68-pin LVD SCSI connector used on most LVD SCSI devices. Refer to your system
and/or SCSI host adapter manual for additional installation procedures that may apply
to your system or host adapter.
1.
Connect the power cables to the AC Power inlets
2.
Connect the remote management Ethernet cable to the controller Ethernet port.
3.
Connect the external serial cable to the controller’s RS-232 Port (phone jack type)
4.
Connect the other end of the external serial cable to the RS-232 Port (DB9 type) on
your host system.
5.
The package comes with two external SCSI cables. For every pair of host channel
SCSI connector at the rear of the subsystem, attach one end of the external SCSI
cable to one of the SCSI connectors and the other end to the host adapter’s
external SCSI connector. (The host adapter is installed in your Host subsystem.)
6.
Attach a SCSI terminator to the other SCSI Host Channel connector (Host Channel
Out port). Make sure to tighten the lock screws of the SCSI terminator.
7.
Connect the other host system using the other external SCSI cable if you want to
configure subsystem into multi-host attachment.
NOTE: When one or more SCSI devices are connected, the total
length of all cables (internal or external) must not exceed 3 meters
(9.8 ft.) to ensure reliable operation.
IMPORTANT: For safety reasons, make sure the Disk Array and Host
Computer are turned off when you plug-in the SCSI cable.
