Dell PowerEdge 6650 - Manual (Page 22)

l Six redundant, hot-pluggable system cooling fans.
l An intrusion switch that signals the appropriate systems management software if the top cover is opened.
l Eight hot-pluggable expansion slots (seven full-length, 64-bit, 100-MHz PCI or PCI-X slots and one 32-bit, 33-MHz PCI slot).
l An integrated VGA-compatible video subsystem with an ATI RAGE XL video controller. This video subsystem contains 8 MB of SDRAM video memory
(nonupgradable). The maximum resolution is 1600 x 1200 with 256 colors.
l An integrated, single-channel Ultra3 SCSI controller for internal SCSI hard drives or internal tape drives.
l An optional dual- or quad-channel RAID controller card for connection to both internal and external storage.
l Optional remote access card that provides remote management capabilities for your system. The remote access card allows you to manage and monitor
your system through a modem or network connection, even when the system itself is down.
l Two integrated 10/100/1000 Mbps NICs, which provide an Ethernet interface.
l Embedded systems management circuitry that monitors operation of the system fans as well as critical system voltages and temperatures. The systems
management circuitry works in conjunction with your systems management software.
l Back-panel connectors include mouse, keyboard, serial, video, two USB, external SCSI, and two NIC connectors.

Power Protection Devices
A number of devices are available to protect your system from the effects of power problems such as power surges, transients, and power failures. The
following subsections describe some of these devices.
Surge Protectors
Surge protectors are available in a variety of types and usually provide a level of protection commensurate with the cost of the device. Surge protectors
prevent overvoltage spikes, such as those that may occur during an electrical storm, from entering the system through the electrical outlet. Surge protectors
do not offer protection against brownouts, which occur when the voltage drops more than 20 percent below the normal power line voltage level.
Line Conditioners
Line conditioners go beyond the overvoltage protection of surge protectors. Line conditioners keep a system's power source voltage at a fairly constant level
and provide protection from brownouts of short duration. Because of this added protection, line conditioners cost more than surge protectors—up to several
hundred dollars. However, these devices cannot protect against a complete loss of power.
Uninterruptible Power Supplies
UPS systems offer the most complete protection against variations in power because they use battery power to keep the system running when power is
unavailable or unusable. The battery is charged by the AC power while it is available so that once power is lost, the battery can provide power to the system
