Scenario 1: Adding a third expansion cabinet
If the existing main cabinet is equipped with two single daughterboards, and
the two expansion cabinets are located within 10 m, adding another expansion
cabinet within 3km requires the following steps:
1 Replace the top daughterboard with a dual port expansion
daughterboard.
2 If the third cabinet is within 10m, add the cabinet to port 3.
Configure the cards required for expansion cabinet 3.
3 If the third cabinet is further than 10m, connect the two short-haul
cabinets to the dual port daughterboards in ports 1 and 3.
4 Replace the lower 10m expansion daughterboard in the main
cabinet with a 3 km expansion daughterboard.
5 Add the third (long-haul) cabinet to the single-port 3 km
expansion daughterboard in port 2.
6 Reassign in software all services provided on cards 21 to 30, to
cards 31 to 40.
Scenario 2: Adding a fourth expansion cabinet
The existing main cabinet is equipped with two 10 m Dual Port expansion
daughterboards connecting to three expansion cabinets. A remote expansion
cabinet is to be added requiring a 3 km expansion daughterboard. Although
one of the existing daughterboards has a port available, it can only be
connected to a cabinet within 10 m (33 ft.). With this scenario, do the following:
1 Select the Dual Port expansion daughterboard that is being used
for only one cabinet (a spare port is available on the
daughterboard).
2 Replace it with a 3 km Dual Port expansion daughterboard.
3 Replace the Receiver card in the existing companion expansion
cabinet with a 3 km receiver card.
4 With glass optic cable, connect the existing expansion cabinet to
the same port as previously assigned on the new expansion
daughterboard.
5 Add the new cabinet to the remaining port as described in
Procedure 3 on page 108.
