Mass-Storage Drives; Hard Disk Drives - HP Vectra XM5 4 Technical Reference Manual

Installing the D3979A Coax Adapter
To use a BNC coax connection, instead of the RJ-45 connection, a coax adapter (D3979A) is
required. Its installation is described in the HP Vectra Accessory Service Handbook (5963-
8034), and is indicated in the HP Vectra PC Service Handbook (Volume 1, 5963-8033).
Switching between the UTP and coax connections is achieved automatically. If both are
connected, and are being used, the UTP connection is given priority, unless specifically
configured by the user.
The adapter draws 200 mA from the main power supply. Consequently, the Remote Power-On
(RPO) facility does not work when using the coax adapter.
The Network Administrator's Guide (5964-1467, or online) is a useful source of further
information.

MASS-STORAGE DRIVES

The IDE controller is described in chapter 2. The flexible disk and tape drive controller is
described in chapter 2.

HARD DISK DRIVES

One of the two 3.5-inch hard disk drive, which is characterized in the table below, is supplied
on an internal rear shelf in some models. The lower 3.5-inch front access shelf can be used to
accommodate an extra hard disk drive (such as D2918A, D2929A, D2925A or D2930A).
