Dell PowerVault 775N (Rackmount NAS Appliance) - Manual (Page 3)

An intrusion switch that signals the appropriate systems management software if the bezel is removed.
System Board Features
Three 64-bit PCI/PCI-X slots located on the riser card (two slots on bus 1 and one slot on bus 2). Slots accept full-
length cards designed for PCI-X up to 133 MHz.
An integrated VGA-compatible video subsystem with an ATI RAGE XL video controller. This video subsystem contains 8
MB of SDRAM video memory (nonupgradable). Maximum resolution is 1600 x 1200 x 16.7 million colors
(noninterlaced).
An integrated, dual-channel Ultra3 SCSI host adapter. The internal channel supports up to five SCSI hard drives on a
1 x 5 or 2 x 3 split SCSI backplane and provides internal RAID support. The SCSI backplane automatically configures
SCSI ID numbers and SCSI termination on individual hard drives, greatly simplifying drive installation.
Memory spare bank feature, which provides your system with failover to a previously reserved row of memory if one
row of memory fails.
An integrated RAID on motherboard (ROMB) incorporates a 128-MB cache memory module, a RAID battery, and a RAID
key.
Two integrated 10/100/1000 NICs, which provide an Ethernet interface.
Integrated 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.
Back-panel connectors including video, keyboard, mouse, two serial, two USB, embedded remote access Ethernet, and
two NICs.
Front-panel connectors including video, keyboard, mouse, and USB.

Supported Operating Systems
Your system supports the Microsoft® Windows® Powered operating system.
Service Features
The system includes the following service features to make troubleshooting and repair easy and effective, in most cases
without tools or service aids:
System diagnostics are available for downloading from the Dell | Support website at support.dell.com.
Systems management hardware and Server Administrator software, which monitor temperatures and voltages
throughout the system and notify you if the system overheats, if a system cooling fan malfunctions, if a microprocessor
overheats, or if a power supply or VRM fails. For information about the systems management option, see your systems
management software documentation.
The system simplifies removing and replacing components. You can replace microprocessors or memory modules
without removing the system board. The SCSI backplane board and hard-drive carriers eliminate the extensive cabling
and drive configuration usually required for a SCSI subsystem.
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.
