Circuit Card Description and Installation
Installing the MSDL card
Procedure 16
Installing the MSDL card
To install an MSDL card follow these steps:
1 Set Device Number S10 and S9.
2 Hold the MSDL by its card-locking devices. Squeeze the tabs to unlatch
the card locking devices and lift the locking device out and away from the
card. Be careful not to touch connector pins, conductor traces, or
integrated circuits. Static discharge may damage integrated circuits.
3 Insert the MSDL card into the selected card slot of the module following
the card guides in the module.
4 Slide the MSDL into the module until it engages the backplane connector.
5 Push the MSDL firmly into the connector using the locking devices as
levers by pushing them toward the card’s front panel.
6 Push the card-locking devices firmly against the front panel of the card so
they latch to the front lip in the module and to the post on the card.
7 Observe the red LED on the MSDL faceplate. If it turns on, flashes three
times, and stays on continuously, the MSDL is operating correctly but is
not yet enabled. Go to step 7.
8 If the LED turns on and stays on continuously without flashing three times,
the card may be defective. Go to steps 8 and 9.
9 Connect the cables. The installation is complete.
10 Unplug the MSDL card and reinsert it. If the red LED still does not flash
three times, leave the card installed for approximately 10 minutes to allow
the card to be initialized.
11 After 10 minutes unplug the card and reinsert it. If the card still does not
flash three times, the card is defective and must be replaced.
