Dell PowerEdge 2500SC - Manual (Page 26)

When connecting external devices to your system, follow these guidelines:
l Check the documentation that accompanied the device for specific installation and configuration instructions. For example, most devices must be connected to a
particular connector to operate properly. Also, external devices usually require you to install device drivers before they will work. Device drivers are normally
included with your operating system software, or with the device itself.
l Always attach external devices while your system is turned off. Then turn on any external devices before turning on the system unless the documentation for the
device specifies otherwise. (If the system does not seem to recognize the device, try turning on the system before turning on the device.)
For information about enabling, disabling, or configuring I/O ports and connectors, see " Using the System Setup Program ."
System Features
Your PowerEdge system offers the following features:
l One or two Intel® Pentium® III microprocessors with an external bus speed of 133 MHz and an internal operating speed of at least 933 MHz
l Front side bus speed of 133 MHz
l Level 2 cache of 256 KB
l Support for SMP, which is available by installing additional microprocessors. SMP greatly improves overall system performance by dividing microprocessor
operations among the independent microprocessors. To take advantage of this feature, you must use an operating system that supports multiprocessing.
l A minimum of 128 MB of system memory, upgradable to a maximum of 4 GB by installing combinations of 64-, 128-, 256-, 512-MB, or 1-GB registered PC-
133 SDRAM memory module pairs in the six memory module sockets on the system board.
l Support for up to eight 1-inch, internal, hot-pluggable Ultra3 SCSI hard-disk drives (six 1-inch hard-disk drives via a 1 x 6 SCSI backplane board, and two 1-
inch hard-disk drives via an optional 80-pin SCA 1 x 2 SCSI backplane board).
l Up to three hot-pluggable, 300 W power supplies in a 2 + 1 redundant configuration.
l Four redundant, hot-pluggable system cooling fans.
NOTE: If you decide to upgrade your system by installing a second microprocessor, you must order the microprocessor upgrade kits from Dell. Not all
versions of the microprocessor will work properly as additional microprocessors. The upgrade kit from Dell contains the correct version of the
microprocessor as well as the correct instructions for performing the upgrade. Both microprocessors must have the same internal operating frequency and
cache size.
