Components

This section provides a descriptive overview of each of the major components that comprise the CR8e subsystem.

Hot Swap Disk Drives

The CR8e uses either 4.2 gigabyte, 9.1 gigabyte, or 18.2 gigabyte high performance, 3.5-inch form factor hot swap disk drives. The drives are designed to operate on the Small Computer System Interface (SCSI) and are Ultra SCSI as well as SCSI-2 command compatible.

Each drive has an 80-pin Wide Single Connector Attachment (SCA-II) interface, designed to allow the drive to be inserted directly into the backplane thus making it possible to “hot swap” the drive without shutting down the subsystem.

The drive mounting design uses a rail system with built-in connectors which allows for easy installation with minimal force. Latching clips ensure that the drive is secured once it is installed.

Hot Swap Cooling Fans

CAUTION: Cooling fans must be replaced by qualified service personnel only.

The cooling system consists of two high-performance fans fitted to the rear panel. These fans draw air from a high pressure plenum, across the drives and electronics of the system and exhaust out through the rear door panel.

The fan speed is thermally controlled to provide reduced operating noise levels. In the event of a fan failure or the cabinet temperature approaches the threshold limit, the remaining fan will switch to maximum operating speed.

Cabinet temperature is measured within the drive bay area between drive slots 2 and 3, and slots 7 and 8. The fan’s speed and alarm are keyed to the higher of the two temperatures. The SAF-TE processor monitors the performance of each of the fans via tach pulses which track the speed (RPM) of each fan impeller.

The fans can be replaced during normal operation without having to power down the CR8e. In the event of a fan failure, the Fan Status LED will illuminate amber and an alarm will sound.
