damage to electronic components.
____________________________________________________________

Prior to Installation
Before upgrading your DIGITAL Personal Workstation, it is important that you follow
these procedures:
1.

Backup all applications and data.
______________Important - Windows NT Systems ________________

For Windows NT systems only: At this point, you must install a new version of “HAL”
code before performing this upgrade.
Turn now to Appendix A, page A-1, and follow the procedure to update the HAL code.
____________________________________________________________
2.

Shut down your system and all peripheral devices.

Unplug the power cord.
________________________WARNING __________________________
Allow at least 15 seconds for the power supply capacitors to discharge
safely.
____________________________________________________________

Remove the system lock, if necessary.

Unplug all cables and option cards.
Because the new riser card comes with an integrated Ultra SCSI controller, the plug-in
disk controller from the old system will be unused.
This extra disk controller may be used for future external storage expansion or the
controller may be discarded.

Remove the six screws.

Remove riser card.
HINT: Refer to your DIGITAL Personal WorkStation User Guide, EK-ALMIG-SI,
Chapter 4, for illustrations of cable locations and removal.
