Installing An Lcb - IBM 3745 Connection And Integration Manual

Step

Installing an LCB

Line connection boxes (LCBs) house up to 15 active remote connectors (ARCs),
thus allowing 15 communication lines to be multiplexed into the same LIC 11. Two
LCBs can be used with the same LIC 11 for a total of 30 lines.
There are two types of line connection boxes (LCBs):
Line Connection Box Base (LCB base or LCBB)
Line Connection Box Expansion (LCB expansion or LCBE)

Plugging in an MAE cable
Note: Make sure that all cables are correctly labeled at both ends
before doing this step.
a. Plug-in the cable into the appropriate connector
b. If not already done at Step 3 on page 3-12, access the command
line interface as follows. Otherwise continue with the Step 5c.
1) In the 3746-9x0 Menu, double-click on Multiaccess Enclosure
(MAE) Management
2) Double-click on Manage Multiacces Encloure
3) Double-click on MOS pushbutton
c. Type T 6 then press Enter twice to reach the Config> prompt
d. Type enable interface ifc x according to the cable you installed.
e. Type write for saving your changes
f. Press Ctrl and P keys
g. Type reload

BEFORE BEGINNING
Do the "Starting Connection Tasks" on page 3-2 before beginning this task.
The LCB base connects to the LIC 11 and contains slots for 15 lines
labelled 0 through 14.
The LCB expansion connects to the LCB base and contains slots for 15
lines labelled 16 through 30.
Location of LCB Installation
LCBs must not be used if not fastened to a table or the floor or not
connected to ground.
IBM recommends LCBs installation in either the 3746-900 base frame, a
19 inch rack, or in a controller expansion (refer to Figure 3-2 on page 3-3
and Figure 3-4 on page 3-4).
– Only IBM representatives can install LCBs in the 3746-900 base frame.
– You can only install LCBs in the 19 inch racks and controller expansion.
