Dell POWEREDGE 1955: System Features

System Features

This section describes the major hardware and software features of your system. It also provides

information about other documents you may need when setting up your system and how to obtain

technical assistance.

• Support for up to ten server modules. The chassis can support from one to ten server modules.

(If fewer than ten server modules are installed in the chassis, server module blanks are required

for proper cooling.)

• Dell™ Remote Access Controller/Modular Chassis (DRAC/MC), which provides access to systems

management software features.

– To access systems management features, connect the null modem cable provided with the system

between the serial management port and an external PC. You may also obtain system management

information through a Web browser connected to the RJ-45 management port. Systems

management software monitors the system and server module status.

– Embedded systems management circuitry that monitors operation of the system fans and critical

system voltages and temperatures. The systems management circuitry works in conjunction with

your systems management software.

• Support for I/O connectivity including pass-through modules and network switch modules. Up to

four I/O modules may be installed. (If fewer than four modules are installed, blank I/O modules are

required for proper cooling.) Optional daughter cards installed in the server modules enable the I/O

connectivity.

• Two hot-pluggable system fan modules. Each fan module has two replaceable fans.

• Two 2100-watt, hot-pluggable power supplies and two power supply blanks, or four 2100-watt,

hot-pluggable power supplies. Two power supplies provide power to the system; two additional power

supplies provide redundancy.

NOTICE: 1200-watt power supplies are not supported.

Server Module Features

• One or two Intel

Xeon

Processor 5000 Sequence.

• Support for symmetric multiprocessing (SMP), which greatly improves overall system performance by

dividing processor operations between independent processors. To take advantage of this feature, you

must use an operating system that supports multiprocessing.

• A minimum of 512 MB of 533-MHz or 677-MHz (when available) DDR II fully-buffered DIMM

(FBD) memory modules, upgradable to a maximum of 32 GB by installing combinations of 256-MB,

512-MB, 1-GB, 2-GB, or 4-GB two-way interleaving memory modules in the eight memory module

sockets on the system board.

The system also supports memory sparing or memory mirroring if all eight memory module sockets are

populated with identical memory modules.
