energy, and if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. However, if this equipment does cause interference to radio or television equipment
reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
!
Increase the separation between equipment and receiver.
!
i
Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
!
Consult the dealer or an experienced radio/television technician for help.
!
Use a shielded and properly grounded I/O cable and power cable to ensure compliance of this unit to
!
the specified limits of the rules.
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference and (2) this device must accept any interference
received, including interference that may cause undesired operation.

Introduction
This
User’s Guide
External RAID Controllers, which are designed to be installed in a RAID enclosure
and used with a host system to provide a powerful disk subsystem.
The G5312 and K5312 RAID controllers are fault-tolerant SCSI-to-SCSI RAID
controllers that bridge the SCSI interface between the host system and the SCSI hard
drive peripherals. They support low voltage differential (LVD) Ultra2 or single-ended
Ultra SCSI buses. The G5312 and K5312 have one Ultra2 SCSI host channel and two
Ultra2 SCSI disk channels. Each disk channel is a separate SCSI bus.
The G7313 and K7313 offer all of the features of the G5312 and K5312 except that
they support Fibre Channel (FC) connectivity, single loop. They each have one FC
host and three Ultra2 SCSI disk channels.
Administrative software is embedded in firmware; thus, the G- and K-Series requires
no specific software drivers for the host operating system.

A fully charged battery can provide a minimum of 72 hours backup time using all
ranges of DIMM sizes. Replace batteries only with the same type as provided by the
manufacturer. Dispose of batteries according to manufacturer’s instructions.
If you must store the battery for a long time, you should take certain precautions to
ensure the battery has sufficient charge when it is returned to service. The
recommended storage temperature is between +5°C to +25°C. Avoid temperature
extremes exceeding -20°C or +40°C for any extended period of time. Exposure to
extreme temperatures causes the battery to discharge at a faster rate and can take
longer to take a full charge when it is returned to service. A new battery or fully
discharged battery can take from four to eight hours or more to fully charge.

Hardware Installation
This chapter explains how to connect the controller in your RAID enclosure to your
network and host computer.
Connecting the Controller
Your controller is already installed in an enclosure. Before you configure the
controller and create arrays, you must connect the controller, which has two types of
data connections:
SCSI channel (G5312 and K5312)—permitting connection to a server (host).
!
Fibre Channel (G7313 and K7313)—permitting connection to other FC
!
devices, typically through an arbitrated loop or SAN with fabric.
RS-232 serial port—for configuration and management of the controller.
!
Connecting to the SCSI Port
You can connect the controller (G5312 and K5312) to a SCSI port. Refer to your
enclosure documentation for the type of connector required.
To connect to the SCSI port:
Be sure the enclosure is turned off.
1
Connect one end of the SCSI cable to the SCSI port on the enclosure.
2
Connect the other end of the SCSI cable to a server’s SCSI port.
3
Connecting to the Fibre Channel Port
You can connect the controller (G7313 and K7313) to an FC HBA or to an FC switch
or hub. You must use proper FC components. Refer to your enclosure documentation
for the type of connector required.
2-1
G- and K-Series User’s Guide
To connect to the Fibre Channel port:
Be sure the enclosure power is turned off.
1
Connect one end of the Fibre Channel cable to the FC port on the enclosure.
2
Connect the other end of the Fibre Channel cable to a server’s HBA or to an
3
arbitrated loop hub or fabric switch.
Turn power on and begin configuration.

Connecting to the RS-232 Port
You use the RS-232 port to update the firmware, configure, and monitor the
controller using a VT-100/ANSI computer with a terminal emulator.
Refer to your enclosure documentation for information about the correct type of cable
to use. Use a 9-pin straight-through cable. A null modem cable does not work.
