Maintaining Quad T1 card 14–5
If you are moving a Quad T1 card to a different slot or replacing a
Quad T1 card to a different slot (original card removed from slot
x, but replacement installed in slot y), follow the steps below
(Physical steps and Configuring the card):
Moving a Quad T1 card is not recommended, because it may
result in a configuration mismatch. However, if a chassis slot is
malfunctioning or is suspected of malfunctioning, you might want
to move a card.
1. Shut down the Controller: Click Start Shutdown, select
Shut down the computer?, and click Yes .
2. After you see the message indicating that it’s OK to turn off
power to the computer, turn off the Controller power
switch.
3. Remove the Controller cover (as explained on page 2–11).
4. Remove any PBX or BTS connections to the back of the
Quad T1 card to be moved or replaced.
5. Disconnect the H.100 ribbon cable (shown in Figure 14-1)
from the card to be moved or replaced.
6. If there are Quad T1 cards in both slots adjacent to the card
to be moved or replaced (that is, on each side), remove the
cable from all cards to the end of the cable in either
direction (so you can remove the card).
7. If the card to be moved or replaced is the first one in a
chain of Quad T1 cards (typically in slot 9), remove the
MVIP cable also. See Figure 14-1.
8. Remove the hold–down screw for the card to be removed.
9. Remove the card by carefully lifting it up.
10. Remove the hold–down screw and blank panel from the slot
where the card is to be installed and insert the blank panel
and screw into the slot the card was removed from.
11. If the card is to be replaced, set the S1 DIP switches
(termination) on the replacement card to match those on the
removed card.
12. If you move a card from the end of a Quad T1 chain to an
inside position, set the S1 DIP switches as follows:
Card on the inside – Disable termination (S1 OFF)
Card on the end – Enable termination (S1 ON)
For further details, see Section 2.5.
