Installing the SCM Card
The DSL cards with an ATM Network Interface (e.g., 8324, 8344, etc.) require the
use of the SCM card. Use a small- to medium-size flat-blade or Phillips
screwdriver to install the SCM card into Slot A. The SCM card is equipped with
lever-type latches that assist in both the insertion and removal of the card. All the
rest of the cards are equipped with ejector-type latches.
Procedure
CAUTION:
Do not insert the SCM card into any slots other than A, as this will
damage the GranDSLAM chassis.
1. If there is a filler plate covering
the slot, remove it.
2. Hold the SCM card vertically and
insert it into the top and bottom
card guides of Slot A.
3. Carefully slide the card into the
slot. Lift the insertion/ejection
latches away from the faceplate
until the card begins to engage
the connectors on the backplane.
Then press in on the latches until
the card is fully seated.
4. Verify that the OK SYSTEM
indicator on the card’s faceplate
is blinking green.
5. Secure the card by fastening the screws on each end of the faceplate. This is
required to maintain proper gasket pressure on the faceplate, as well as
proper air flow.
6. Attach the appropriate cables to the connectors protruding through the SCM
faceplate.
