Enova Digital Media Switchers - Hardware Reference Manual
ESD WARNING: To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are properly grounded
before touching any internal Enova DGX materials. Use an ESD wristband and cord with an alligator clip attached to a good
ground source.
To remove and replace an Enova DGX CPU board assembly:
NOTE:
If Audio Switching Boards are in the enclosure, remove them before beginning the following instructions.
1.
Turn off AC power to the enclosure. Make sure none of the power supply LEDs are illuminated.
2.
Disconnect all cables connected to the CPU and unplug the AxLink connector.
3.
Remove the screws from CPU faceplate per the locations indicated in FIG. 155 (four screws in Enova DGX 6400, three
screws in Enova DGX 800/1600/3200).
4.
Remove the CPU faceplate and set aside.
5.
Use the removal tab indicated in FIG. 156 to pull the CPU board assembly straight out of the enclosure.
6.
Place the old (100 Series) CPU board in an ESD approved static shield bag and set aside.
7.
Slowly slide the replacement CPU board into the empty slot, being careful to align the edges in the board guides
along the insides of the slot (FIG. 157).
8.
Push on the CPU removal tab (FIG. 156) firmly enough for the board to make a good electrical connection (avoid
pushing on the connectors). When the CPU board is fully inserted, its faceplate should sit flush with the back metal.
9.
Set 100 Series CPU faceplate aside and reattach the Enova DGX 8/16/32/64 faceplate provided with the CPU.
10.
Apply power to the enclosure.
11.
Check the CPU’s System Status LED for indications of normal display (see table below).
