    The drive should be verified in the mode it will be attached to the system. It cannot be assumed that a drive which attaches as an additional SCSI device on a system providing only additional data storage will have no problems when attached as the only/boot drive.
  • Page 8 No modifications to the drive are required. However it is necessary to modify the list of device types on the table of known drives contained in the 'usr/sys/data/scsi-data,c' system file as follows: Change first line from '/*UNKNOWN DISK*/' TO '/*IBM OEM*/'. Following this change, the operating system kernel must be rebuilt (recompiled).

    For a single-ended cable, a 50-conductor flat cable or a 25 twisted pair cable can be used, with a maximum length of 6.0 meters and a stub length not to exceed 0.1 meters. This file has a maximum internal stub length of 0.072 meters on all SCSI signals except -RST; the -RST signal has an internal stub length of 0.096 meters.

    Note: Screws must not penetrate more than 3.8 mm TEMPERATURE MEASUREMENTS Temperature measurements should be made at the points shown Figure 3 to ensure that the maximum values are not exceeded under any circumstances. Forced air cooling may be required in order to achieve this.

    The file's mounting frame is electrically isolated from the file's disk enclosure. The disk enclosure is not at ground potential. Therefore any user mounting scheme must not result in the disk enclosure being shorted to ground. To prevent external electrical noise form interfering with the file's performance, the file's mounting frame may be electrically isolated from the system mounting frame.
