interface cable with this device. If the equipment has more than one interface
connector, do not leave cables connected to unused interfaces unless otherwise
instructed to do so in the user manual.
•Changes or modifications not expressly approved by the manufacturer could void the
user's authority to operate the equipment.
Cautions
•Take precautions to prevent electrostatic discharge (ESD) damage before handling the
ICP RAID Controller.
•ESD can damage controller components. Perform the described procedures in this
guide only at an ESD workstation. If no such station is available, you can provide some
ESD protection by wearing an antistatic wrist strap and attaching it to a metal part of
the computer chassis.

5. For internal SCSI channel connection:
a. Connect one end of the SCSI cable to the internal 68 pin LVD SCSI connector
located on the ICP RAID Controller card.
b. Connect the other end of the SCSI cable to the SCSI device.
Note: Ensure that the end of the SCSI bus is properly terminated. See Section 2.2.3
for termination details.
6. Replace the system cover and reconnect power cords.
Warning: Attention the controller can get HOT ! Controller requires constant airflow for
cooling (min 1m/sec).

J1—SCSI termination power: If the SCSI port is used, at least one device has to supply +5
volts termination power to the SCSI bus.
J2—SCSI bus termination: If the SCSI port is used, use this jumper to set termination.
J9—MIA voltage on HSSDC 2 (FC2): If you are using a 5 volt MIA in the FC-AL port,
you must change the jumper to the 5 volt setting.
J10—MIA voltage on HSSDC 1 (FC1): If you are using a 5 volt MIA in the FC-AL port,
you must change the jumper to the 5 volt setting.
2.2.3 SCSI Termination
Termination is critical when connecting SCSI devices together. Connected SCSI devices
are typically called a SCSI bus, and termination is required at the each end of the SCSI
bus. Use a high-quality terminator at the end of the SCSI cable after the last device in the
bus to ensure proper termination.

This section provides general instructions for connecting Fibre Channel (FC) enclosures
to an FC-enabled ICP RAID Controller.

Hardware Installation
2.3.1 Configuring Single and Dual Loop Connections
The GDT8522RZ and GDT8622RZ ICP RAID Controller products each provide a 2Gb
serial interface and contain 2 HSSDC ports.
Note: Use connectors that are appropriate for your FC-enabled ICP RAID Controller, FC
cabling, and FC enclosure. See Appendix B for information about Fibre Channel cabling
and connectors.
1. Install the ICP RAID Controller card into the computer. (See Section 2.2.1 for details).
2. Connect one end of the FC cable to one port on the ICP RAID Controller card.
3. Connect the other end of the FC cable to one port on the FC enclosure.
4. Verify loopback requirements on the FC enclosure. (See Section 2.3.2 for details).
To configure a second loop:
5. Connect one end of the FC cable to the second port on the ICP RAID Controller card.
6. Connect the other end of the FC cabling to the second channel on the FC enclosure.
7. Verify loopback requirements on the FC enclosure. (See Section 2.3.2 for details).
2.3.2 Fibre Channel Loopback
In Fibre Channel configurations, loopback (or loop completion) is always required.
Loopback sends data from an FC connector’s “send” side to its “receive” side, effectively
completing the loop. Many manufacturers of FC enclosures use a backplane with built-in
fibre channel loopback capability. (Check your drive enclosure users manual for details).
If loopback is not handled by the FC enclosure, you must attach a loopback connector on
the enclosure port you are using to configure a fibre channel loop. If your fibre channel
configuration includes multiple chained enclosures, loopback is required on the last
device in the chain.
2.4 ICP RAID Controller Diagnostic Features
The GDT8522RZ and GDT8622RZ ICP RAID Controller products have LED indicators,
an 80db audible alarm, and boot-up beep sequences that can help diagnose the RAID
Controller.

2.4.1 LED Indicators
There are several sets of LED indicators on the GDT8522RZ and GDT8622RZ ICP RAID
Controller products. Some LED indicators reside near the ports on the ICP RAID
Controller card bracket (see Figure 2-6) while all other LEDs reside on the front of the
ICP RAID Controller card (see Figure 2-7). See Table 2-2 for descriptions of the LED
indicators.

2.4.2 Audible Alarm
The GDT8522RZ and GDT8622RZ ICP RAID Controller products contain an 80db
audible alarm that is controlled by the RAID firmware. The alarm indicates these events:
•State of controller upon boot-up
•Change in the normal state of the array
•Change of controller environmental status (during normal operation)
•Failure of hardware that the controller manages
If the cause of the event is resolved and/or removed, the audible alarm will cease. You can
also turn off the audible alarm manually through ICPCON or ICP RAID Navigator. If you
use these management tools to silence the alarm, it will only be disabled for the current
event and will be ready to sound again at the next event.

In ICPCON, under Advanced Setup > Configure Controller, press <F4> to silence alarm.
Note: The <F4> option is only available if the alarm has been activated.
