Upgrading your RaQ 4

The RaQ 4 unit is a single rack-unit (1RU) enclosure. Before you purchase a

component to add to the RaQ 4, ensure that the component ﬁts into the allocated

space:

• The DIMM modules must be less than 1.5 inches (38.1 mm) tall and less

than 0.158 inches (4.0 mm) thick.

• The PCI expansion slot has been designed to accommodate the PCI standard

short card form factor, with some additional space for longer cards. The PCI

card must be less than 10.5 inches (267 mm) long.

There are three ways to upgrade your RaQ 4:

• add a memory module

• add a PCI expansion card (not available on the base RaQ 4 conﬁguration)

• add or replace a hard disk drive (see “Adding or replacing a hard disk drive

in a RaQ 4” on page 164)

Opening the RaQ 4

1. Power down the RaQ 4. See “Powering down” on page 155.

2. Unplug the RaQ 4 from the power supply.

3. Remove the power cord from the rear of the RaQ 4. The cable is located

beside the power switch. See Figure 2 on page 5.

4. Unscrew the top cover of the RaQ 4. Ten screws hold the top cover in place.

The screws are labeled 1 through 10 in Figure 59.

Warning: You must power down the RaQ 4 before opening the unit.

✍

Note: If the RaQ 4 is mounted on an equipment rack, remove the

RaQ 4 from the rack and take it to a service area. Do not attempt

this upgrade while the RaQ 4 is still in the equipment rack.
