Racking Density; High-Availability Slider Rails; Cabinet Spacing Requirements; Standalone (Rackless) Configuration - HP rx2600 Overview

Removing the front bezel and a sheet-metal section that covers the top one-third and front of the server provides
access to the memory and processor boards. Memory can be easily added to the server (when powered off)
without removing the memory carrier. Depending on your choice of memory carriers, up to 16 or 32 dual in-line
memory modules (DIMMs) can be loaded into the server. Both the memory carrier and processor boards can be
easily removed without tools by unlatching and sliding them forward.
A media bay located at the lower front of the server accepts an optional, slimline DVD drive. Located to the right
of the media bay are the power switch and LED indicators for system status. A pair of hot-plug, low profile disk
drives are located in the lower right-front corner of the server.
Three pairs of redundant, hot-swap fans span the width of the server behind the processor board, memory board,
and other assemblies located in the front half of the server.
Behind the bank of fans are two hot-swap power-supply bays at the right rear of the server. Each power supply
has a pull-through fan where air exits at the rear. To the left of the power supplies and behind the bank of fans are
eight PCI-X slots. Factory-installed SCSI controller and Ethernet LAN cards occupy two of these slots. The remaining
six PCI-X slots have hot-plug capability and can be loaded with I/O cards selected by the end user.

Racking density

The rx4640 offers unparalleled performance density. At four EIA units per server, up to ten servers can be
installed into a single 2-meter rack cabinet.
The rx4640 is supported in HP Rack System/E, 10000 series, 9000 series and 7000 series rack cabinets. The
rx5670 is also supported in a variety of third-party, non-HP racks and cabinets. Refer to the HP Server
Configuration Guide for the latest list of qualified third-party racks.
Note: Dimensions for rack configuration: H = 6.8 inches (17.3 cm), D = 27.2 inches (69.0 cm),
W = 19 inches (48.2 cm).

High-availability slider rails

The rx4640 comes standard with a pair of side-mounted high-availability (HA) slider rails, which use no
additional vertical space and can be installed without tools. With the HA slider rails, the unit can be completely
serviced without removing it from the rack, thus allowing side-by-side racks of systems to be completely supported
without sacrificing floor space for side access to the system.

Cabinet spacing requirements

The rx4640 requires a minimum of 24 inches (61 cm) of free space in both the front and rear of the cabinet for
proper ventilation. During product installation and servicing, a total of 30 inches (76 cm) of free space is needed
at the front of the cabinet.

Standalone (rackless) configuration

When a cabinet is not desired, the rx4640 is also available in a standalone (rackless) configuration. The
standalone system is ideal for a back room or on a shelf; however, the standalone server should not be placed in
an office environment due to acoustic and RFI characteristics. The standalone configuration utilizes the same
internal chassis and front plastic bezel as the racked version. A tubular steel frame attaches to the sides and
wraps around the bottom of the server. The rx4640 can be positioned either on its bottom or side when the
tubular frame is attached. The frame also makes it easy for two people to pick up and move the server. Up to
three rx4640 servers can be stacked in a horizontal position, as in a rack, with plastic brackets that snap onto the
steel tubes.
Note: Dimensions for standalone configuration: H = 10.28 inches (26.1 cm), D = 27.36 inches (69.5 cm),
W = 20.95 inches (53.2 cm).
