Nortel Meridian 1 Option 11C Upgrade Manual page 21

Upgrade a single-cabinet system to Option 11C
10 (Optional step) If you plan to add one or more expansion cabinets
as part of the upgrade, install a Fiber Expansion Daughterboard.
Note: You can complete this step after you have upgraded the main
cabinet to Option 11C. However, you can prevent additional downtime
by installing any required Fiber Expansion Daughterboards now. Refer
to the Option 11C Planning and Installation Guide
detailed information about adding expansion cabinets to an existing
system.
The fiber-optic interface product used in the Option 11C is considered
safe. However, as a precaution, do not look directly at the optical port
or the end of the fiber-optic cable. Under some conditions, the cable or
port can cause eye exposure beyond the limits of Maximum
Permissible Exposure recommended in some areas. Do not remove
protective caps or plugs until ready to connect the cable.
a Install the Fiber Routing Guide as shown in Figure 3 on page 23.
The P0816832 Fiber Routing Guide can hold a maximum of two
fiber-optic cables. Use it in cabinets that are operating software
released before X11 Release 24 software. The P0888475 Cable
Routing Guide can hold up to four cables. Use it in cabinets that
run X11 Release 24 and later versions of software.
b Install a Fiber Expansion Daughterboard on the NTDK20 SSC
card for added expansion cabinets, as shown in Figure 2 on page
20.
There are two types of expansion daughterboards: single port and
dual port. Single port expansion daughterboards are compatible
with all versions of NTDK20 SSC cards. Dual port expansion
daughterboards require an NTDK20CA or later version of the SSC
card.
