Intel II manual Hot-swap Bay, Scsi Hard Disk Drives

Hot-swap Bay

The plastic front door covers a removable metal EMI cover that is hinged at the bottom. Plastic drive carriers for 3.5-inch wide by 1-inch high drives allow easy hot-swapping of drives without shutting down the system.

The backplane uses industry-standard 80-pin SCA2 connectors to support up to five industry- standard Ultra2/LVD SCA2 SCSI hard disk drives. The bays accept peripherals that consume up to 17 watts of power and run at a maximum ambient temperature of 50 °C.

SCSI Hard Disk Drives

The system supports a variety of single ended or LVD (low voltage differential) SCSI SCA2 devices. Visit the support website for your server board for a list of approved single ended SCSI SCA2 devices. http://support.intel.com/support/motherboards\server\

WARNING

The Ultra2/LVD SCSI hot-swap backplane requires installing LVD or single ended SCSI devices in your system. Installing high voltage differential (HVD) SCSI drive types can result in electrical damage to the server board and the peripherals.

CAUTION

ESD can damage disk drives, add-in boards, and other components. This server can withstand normal levels of environmental ESD while SCSI hard disk drives are being swapped. However, we recommend doing all procedures in this manual only at an ESD workstation. If one is not available, you can provide some ESD protection by wearing an antistatic wrist strap attached to chassis ground of the server—any unpainted metal surface—when handling components.

For proper air flow and hard drive cooling, make sure that the paper baffles included with the chassis are installed in any drive carriers that do not contain drives. Fold the ends of the paper baffle up along the dotted lines.

Mounting a SCSI SCA2 Hard Disk Drive in a Plastic Carrier

1.Record the drive model and serial number in your equipment log.

2.Orient the drive so the connector is near the top surface of the drive, and place it on an antistatic surface.

3.Place the plastic carrier on top of the drive.

4.￿Using four screws (silver screws with washers are supplied), attach the carrier to the drive.
