SCSI
Models: DCHS-04F, DCHS-04W, DCHS-04E, DCHS-04S, DCHS-04U, DCHS-04X, DCHS-04Y, DCHS-09F, DCHS-09W, DCHS-09E, DCHS-09S, DCHS-09U, DCHS-09X, DCHS-09Y
Handling precautions
1.Do not cover the breather hole! Covering the breather hole may result in loss of data.
2.Do not press on the drive! Do not apply any force to the drive during handling or installation.
3.Always handle the drive with care to prevent damage from shock, vibration, or electrostatic discharge (ESD).
4.Do not open the static-protective bag containing the drive until required. Static electricity can damage the drive.
5.Turn off and unplug your computer. Remove cover.
6.When installing the drive, touch a grounded, unpainted metal surface with the static-protective package containing the drive for at least two seconds. (This drains static electricity from the package and from your body.)
7.Handle the drive carefully by the edges. Do not touch any exposed printed circuit board.
8.Save the drive packaging material including the ESD bag in the event that the drive must be returned. Place the drive in an anti-static bag before placing it in the shipping container. The warranty will be void if the drive is not returned in IBM approved packaging.
Quick installation procedure
This procedure may require use of a bootable System Diskette containing FDISK.COM and FORMAT.COM.
Setting the address
1.Each drive on the SCSI bus must have a unique address. Fifty-pin (Narrow SCSI) devices have eight possible addresses (0-7) with address 7 (highest priority) normally reserved for the controller. Sixtyeight pin (Wide SCSI) devices have 16 possible addresses.
2.SCSI address bits 3 (68- & 80-pin models only), 2, 1, and 0 of the 32-pin Option Jumper Block are used to select the SCSI device ID.
