Slot numbering and module placement
LIM are installed in the slots numbered from 1 to 4 in the front of the Stinger MS+
chassis. These slots are also logically referred to by the TAOS software as slots 1
through 4, corresponding with their physical location in the chassis.
The top slot in the front of the unit is labeled “CTRL”. This slot is reserved for the
control module. To maintain the uniformity across the Stinger product line, this slot
is logically referred to by the TAOS software as slot 8.
The top slot in the rear of the unit is labeled “TM”. This slot is reserved for a trunk or
TRAM module. To maintain the uniformity across the Stinger product line, this slot is
logically referred to by the TAOS software as slot 17.
Installing and replacing LIMs
Physical installation and replacement of a LIM are similar procedures to the
installation and replacement of a control module. Refer to the illustration in
Figure 6-2 on page 6-4, if necessary.
Installing a LIM
To install a LIM:
1
Put on the antistatic wrist strap, as recommended in “Preventing static discharge
damage” on page 1-4, and plug it into the ESD grounding jack located on the
front of the unit. (See Figure 1-5 on page 1-7.)
2
Remove the blank slot cover on the desired slot on the front of the unit. (See
“Slot numbering and module placement” on page 6-5.)
3
Align the LIM with the card guides and carefully slide the module into the unit.
Note
Keep the connector on the LIM being inserted away from components on
adjacent LIMs. Do not force the card. Once the card has engaged its bus
connector, press firmly to be sure it is fully seated.
4
Depress the ejectors simultaneously.
5
Slide the card ejector lock up.
6
Using a number 2 Phillips screwdriver, secure the LIM by tightening the
thumbscrews.
7
If necessary, if all other installation tasks are complete, including the installation
of an associated LPM, turn on power to the Stinger unit.
8
Wait several minutes and then verify the behavior of the status lights on the LIM
to verify its operational status.
For status light information, see the module guide for the LIM you are installing.
Replacing a LIM
!
Caution
Lucent Technologies recommends setting the administrative status of the
LIM to Down (through the command-line interface) before replacing the module.
When a LIM is removed, all its ports and circuits are terminated, and data loss might
occur. For instructions on changing a LIM’s state to Down and then back to Up, see
the
Stinger Administration Guide
.
