Error Diagnostics And Suggested Corrective Actions; Mass-Storage Drives; Hard Disk Drives - HP Vectra VT6 Technical Reference Manual

For the temporary storage of data received or awaiting transmission over the network, the A model
has a 128 KB packet buffer . The B model has a 32 KB packet buffer.
The new, enhanced demand priority access (DPA) protocol guarantees access to any end node
that requests to transmit, while ensuring priority access to end nodes that require consistent, and
thereby, continuous access for applications such as full-motion video or video conferencing. This
protocol, through being collisionless with priority allocation, allows you to minimize unused
capacity on your network, and so maximizes network throughput.
The A model can be configured completely by software (no switches or jumpers need changing).
The controller can be I/O mapped or memory mapped: the fastest mode is automatically selected
by the driver. An HP provided driver needs to be installed within the operating system.
The B model is I/O mapped, and has Bus-Master capability.
The HP Vectra XU 6/xxx PC is supplied with a multi-protocol boot program integrated within the
System ROM, and has a complete LAN client drivers and diagnostics package (Microsoft client,
Novell client, IBM LAN server client and Warp connect, Banyans client, DEC pathworks client, all
major TCPIP stacks, Lantastic).

ERROR DIAGNOSTICS AND SUGGESTED CORRECTIVE ACTIONS

Diagnostic software, in the form of a DOS utility called HPVGSet , is provided on the XU/VT
Drivers and Documentation CD-ROM.
The LAN administrator's guide (provided in ASCII, WINHELP and HTML format) is a useful source
of further information. The HP 10/100 VG Selectable PC LAN Adapters Installation Guide (5963-
2665) contains detailed diagnostic information.

MASS-STORAGE DRIVES

The SCSI and IDE controllers are described in chapter 2. The flexible disk controller is described
in chapter 2.

HARD DISK DRIVES

A 3.5-inch hard disk drive is supplied on an internal shelf in some models of the HP Vectra XU
6/xxx PC and the HP Vectra VT 6/xxx PC .
