With the handles extended, carefully pull the board straight out of the board slot (FIG. 45).
Place the board in an ESD approved static shield bag.
Caution: Each Epica DGX 144 board has an EMI (Electromagnetic Interference) gasket along the
right edge of the face plate to make sure the boards fit snugly. Handle the boards carefully to avoid
dislodging or damaging this gasket on the board being installed and on the board to its left.
Caution: For SC Fiber boards, do not remove dust plugs from the SC fiber connectors until Step 12.
5.
New board – With the board’s extractor handles in the extended (unlocked) position, line up the
board’s edges on the board guides that are along the top and bottom of the board slot (FIG. 1).
Begin pushing the board into the slot until each extractor starts to engage its metal extractor plate
(lift into its folded position).
When the extractor handles start to lift, flip the handles toward the middle of the board until they
snap into their folded (locked) positions (which firmly seats the board).
6. If the enclosure was powered down – Reapply power.
7.
Establish serial communication with the enclosure:
a. Attach a PC to the serial port on the enclosure with an RS-232 null modem cable (pinout:
5 GND to 5 GND, 2 RXD to 3 TXD, and 3 TXD to 2 RXD).
b. Open HyperTerminal (typically at start/Programs/Accessories/Communications/HyperTerminal)
and set the port settings to: baud rate = 9600, data bits = 8, stop bit = 1, parity = none, and flow
control = none.
8. If the enclosure was not powered down – Enter
~app!
in HyperTerminal to execute a soft reboot
of the system.
