DECpc 525-MB IDE Hard Disk
Drive Installation Guide

EK-XARCG-IA-A01

If you install the drive in a DECpc 400 ST, you need an IDE cable. The cable is not
included with this kit and must be ordered separately. The Digital part number is
BC10N-3E.

Before You Start

Read the following installation instructions. If you are unsure about your ability to
install the drive, you can contact Digital Services to hire a Digital Services technician
to install the drive for you.

If you are replacing a drive, or adding a second drive, always back up the data before
starting the installation.

The drive can be connected directly to the 40-pin IDE-bus connector located on the
DECpc motherboard, or to a separate IDE-bus adapter board.

______________________ CAUTION ________________________

Static electricity can destroy the circuits on the drive's circuit
board. Discharge static electricity by touching the drive's metal
frame before touching the circuit board.
