Access to Components
Be certain to shut down the Broadcast Time Delay, turn off the rear
panel power switch and disconnect the power cord before opening the
unit for service.
The following sections provide instruction on disassembly and re-assembly for maintenance.
The front panel is removed to access the internal CD-ROM drive (for system program updates), or
to service the hard drives.
The top cover is removed to access the analog/digital audio selection jumpers, or to service an I/O
card, the system board, or power supply.
Removing the Front Panel
The front panel is easily removed for access to the CD-ROM drive, the four disk drives, or for
removing the server from an equipment rack. Using a coin or a flat-blade screwdriver, unscrew the
two large panel fasteners on the left and right sides of the face panel. Hold the panel in place while
undoing the screws. Since the loosened screws are captive, you may use them to pull the panel away
from the chassis.
To re-install the front panel, tuck all wires into the chassis and move the face panel into position.
Screw the front panel fasteners back into the chassis. Tighten the front panel access screws with a
screwdriver.
NOTE: The Broadcast Time Delay is vulnerable to accidental system reset while removing or re-
installing the front panel. It is recommended that the front panel be removed or attached only while
the system is OFF. The system can be powered ON for program updates with the front panel
removed.
