Dell PowerEdge 2600 - Manual (Page 28)

Replacing the Cover
1. Ensure that no tools or parts are left inside the system and that any cables are routed so that they will not be damaged by the cover.
2. Align the cover with the cover alignment hooks on the sides of the chassis, and slide the cover forward (see Figure 4 -3 ).
3. Tighten the three thumbscrews that secure the cover to the chassis.
4. Replace the bezel (see " Replacing the Bezel ").
Inside the System
In Figure 4 -4 , the covers and bezel are removed to provide an interior view of the system.
Figure 4-4. Inside the System
The system board holds the system's control circuitry and other electronic components. Several hardware options, such as the microprocessors and memory,
are installed directly on the system board. The system board can accommodate up to seven PCI or PCI-X expansion cards (two PCI or PCI-X cards at 64-
bit/33-133 MHz, four PCI or PCI-X cards at 64-bit/33-100 MHz, and one PCI card at 32-bit/33 MHz).
The peripheral bay provides space for a 3.5-inch diskette drive, a CD drive, and two hard drives.The hard-drive bays provide space for up to five 1-inch SCSI
hard drives. The hard drives connect to a controller on the system board or a RAID controller card through the SCSI backplane board. For more information,
see "
Hard Drives ."
The hard-drive bays provide space for up to six 1-inch hard drives. These hard drives are connected to a SCSI host adapter on the system board or on an
expansion card, by way of the SCSI backplane board.
The power supply distribution board (PSDB) provides power distribution for the system. One front-loadable power supply slides into connectors mounted on
the PSDB to provide power to the system board and internal peripherals. An option for a second hot-pluggable power supply to provide redundant power is
available.
For non-SCSI drives such as the diskette drive and CD drive, an interface cable connects the interposer board, attached to the diskette drive and CD drive, to
the system board. For SCSI devices, interface cables connect externally accessible SCSI devices and the SCSI backplane board to a SCSI host adapter either
on the system board or on an expansion card. For more information, see "
Installing a Hard Drive ."
During an installation, repair, or troubleshooting procedure, you may be required to change a jumper. For information on the system board jumpers, see
"
Jumpers and Connectors ."
