1U – One rack unit (1U) is 1.75 inches or 44.45 mm in vertical dimension. The height of a
device, or form-factor, can be expressed in rack units (Us), for example 1U, 3U, 7U. The
actual height of a device is somewhat less. For example, while the ProLiant DL360 server
is considered to be a 1U server, its actual height is 1.65 inches. This slight reduction in
height prevents mechanical interference between two servers that are mounted in adjacent
places in a rack.
Fixed-Rail – The fixed server rails are factory-installed in each ProLiant DL360 server. The
matching fixed rack rails shipped with the server are to be installed on Compaq 9000-
and 7000-series racks. The fixed rack rails are spring-loaded so that they can be installed
easily by one person. When using fixed rails, servicing of a
ProLiant DL360 server requires disconnecting all cables from the
server and removing the server from the rack.
Flat Panel Display (FPD) – The Compaq TFT5000R (15-inch) Flat
Panel Monitor provides large viewable image size and exceptional
screen performance in a space saving 2U-form factor for rack usage,
allowing the monitor to be neatly tucked away when not in use.

High Voltage – AC line voltage of 200V to 240V. Higher voltage
level means lower current for the same amount of power requirement for a server.
Compaq recommends a high voltage source to support high volume deployments of
ProLiant DL360 servers in a rack.
In-Rack Keyboard – The 1U Rack Keyboard Drawer and the
Internal Keyboard with Trackball are designed to work together to
save room in space-constrained rack-mount environments. The
1U Keyboard Drawer requires only half the Compaq rack depth
and provides enough space behind it to mount a Compaq Server
Console Switch.

Keyboard/Video Mouse (KVM) – This abbreviation is used to refer to Keyboard/Video/Mouse
cable or switch. KVM switches also are referred to as Server Console Switches in
Compaq parts lists.
Local Console – A server console system incorporates a set of KVM (keyboard, video and
mouse) devices. The word “local” in this context describes the relatively close proximity
of the console from the server, and how the console function is accomplished without the
use of a network connection. The console can be attached either directly to the server or
indirectly via a KVM switch. Local-console implementations are limited to controlling
