Field Replaceable Units (FRUs) FRU Removal and Replacement Removing the Top Panel To remove the top panel, do the following: 1. Remove the two thumbscrews in the top left and right corners of the workstation's rear panel. NOTE The upper-left thumbscrew has a power supply interlock. Removing this thumbscrew disengages all power outputs of the power supply, reducing the shock hazard while removing and replacing internal FRUs. However, be aware that cutting off power to the workstation via this power supply interlock does not do a clean shutdown of the workstation. Instead, press the power switch on the front panel to shutdown the workstation properly. 2. Firmly grip the top panel and slide it an inch or two away from the front edge, toward the rear of the workstation. 3. Remove the top panel by lifting straight up. Figure 4-4. Removing the Top and Side Panels To replace the top panel, see "Replacing the Top and Side Panels" on the next page. Chapter 4 93

FRU Removal and Replacement
Removing the Top Panel
To remove the top panel, do the following:
1.
Remove the two thumbscrews in the top left and right corners of the workstation’s rear
panel.
NOTE
The upper-left thumbscrew has a power supply interlock. Removing this
thumbscrew disengages all power outputs of the power supply, reducing the
shock hazard while removing and replacing internal FRUs. However, be
aware that cutting off power to the workstation via this power supply
interlock does not do a clean shutdown of the workstation. Instead, press the
power switch on the front panel to shutdown the workstation properly.
2.
Firmly grip the top panel and slide it an inch or two away from the front edge, toward
the rear of the workstation.
3.
Remove the top panel by lifting straight up.
