Alarm Speaker 11
Alarm Speaker
An audible alarm will sound when any component’s condition changes to an
abnormal state. The Status Indicator LEDs conditions (color and/or state) will
provide a general area of failure, and the failed component can then be identified
using the Operator Control Panel.
To silence the alarm, access the control panel and select “Turn Off Alarm.” For
more information see Main Menu on page 42.
Fault LEDs
When a disk drive is installed in a drive slot, it has a corresponding Drive Fault
LED that will illuminate to aide in identifying a failed or problem disk drive.
These LEDs are located on the inside front door panel and are aligned with their
respective drive slot. If the LED is illuminated (amber), the condition indicates a
failed or problem drive found in that drive slot.
SAF-TE Card
The SAF-TE card contains the control and monitoring electronics for the
subsystem cabinet. It provides the central data link between the enclosure and the
host system.
Located in the tower-based systems’ top bay (the rack-mount systems’ far left bay)
are two card slots. The SAF-TE card is installed in the lower (furthest right) of
the two slots. The upper slot (furthest left slot) is not used.

SAF-TE

The CR8e is designed to be compliant with version 1.0 of the SAF-TE (SCSI
Accessed Fault-Tolerant Enclosure) specification. Under this specification, the
enclosure is implemented as an assignable SCSI target ID. This allows
standardized alert detection and status reporting using the SCSI bus as the
underlying transport mechanism.
