Dell PowerEdge 4600

SCSI Backplane

The PowerEdge 4600 backplane uses a modular design consisting of a backplane circuit board and an optional daughter board termination card.

This is a picture of the PowerEdge 4600 backplane subsystem

Key features of the SCSI backplane:

Eight hot-plug capable Ultra3/LVD SCSI slots with three LED indicators per slot
Two 68-pin SCSI connectors for connecting LVD SCSI controllers to the backplane
A set of quick-switches for splitting the SCSI bus
One slot for connecting a daughter card board to the backplane
The SCSI backplane will operate in a 1 x 8 or a 2 x 4 configuration
In order to split the backplane the daughter card must be inserted
Empty drive bays use a blank drive carrier to maintain proper cooling, a uniform appearance to the unit, and to provide EMI shielding

Removing the SCSI Backplane


	Step 1: Disconnect the SCSI cables and the power cables from the backplane.





	Step 2: Loosen the thumbscrew located on the backplane.





	Step 3: Slide the SCSI backplane away from the system board and lift it towards the back of the system.

Daughter Board

The 1 x 8 SCSI backplane can be split to a 2 x 4 via the installation of an optional daughter board. Below are the steps for removing the optional daughter board.

Before removing the split backplane card, the following steps must be performed:

Remove the front bezel.
Remove the system cover.

Removing the Daughter Board


	Step 1: Pull the split backplane card handle to create a 90° angle with the card.





	Step 2: Pull the split backplane card towards the front of the server then pull up to remove it from the system.
