Opening the Subchassis and Electronics Bay

The chassis is comprised of three parts: the main chassis, a swing-out subchassis at the front, and a swing-out subchassis, called the electronics bay, at the rear. To access components in some instances, you must remove the foam covers and swing away and/or completely remove the subchassis and electronics bay.

To open the subchassis and electronics bay, you must first remove the foam covers. The subchassis and electronics bays are secured using phillips head screws.

To Open the Subchassis and Electronics Bay

1.Observe the safety and ESD precautions in “Static Electricity Precautions” on page 2.

2.Turn off all peripheral devices connected to the system.

3.Turn off the system power by using the power on/off switch on the front panel and unplugging all AC power cords.

4.Label and disconnect all peripheral cables attached to the I/O panel on the back of the system.

5.Remove and save the three screws from the back of the access cover; you will need them later to reattach the cover.

6.Remove the access cover.

7.Remove the foam blocks by pulling them out of the subchassis and electronics bay. These blocks form an important part of the airflow and electromotive compatibility (EMC) characteristics of the system. The foam in the subchassis also forms the support structure for most of the system fans.
