so that its tabs firmly engage in the slots, until it
stops at the edge of the front bezel. If the cover does
not slide freely all the way forward, make sure the
padlock slot is correctly placed over the loop on the
chassis back.
6. Reinstall the two retaining screws at the back of the
chassis removed earlier, and tighten firmly.
7. To prevent unauthorized access inside the system,
insert and lock a padlock through the loop at the
back of the chassis.
Note: If your system is already set up, plug the system
back in, reconnect the peripherals, and power on the
peripherals and system.
Removing a Side Panel
Note: The side panels do not have to be removed in
order to install or remove any boards.
Caution: For proper cooling and airflow, do not
operate the system with the side panels removed.
Always replace the panels before powering on the
system.
Caution: Do not damage or displace the EMI strips
mounted on the inside of the panels as you remove and
install them. Replace any damaged strips, or your
system may not meet EMI requirements.
Warning: If you are removing the side panel after the
system is set up, you must first power off the system
and all external devices. Unplug the system power
cord.
To remove a side panel:
1. Power off the system and ensure it is disconnected
from the ac wall outlet.
2. Observe the safety and ESD precautions listed at
the beginning of this chapter.
