553-3021-250 Standard 7.00
Note 2: If you plan to add a second Fiber Expansion Daughterboard
as part of the upgrade, do it now to prevent additional downtime later.
Install it to the connector labeled "Fiber 2." Refer to the Option 11C
Planning and Installation Guide
information about adding expansion cabinets to existing Option 11C
systems.
14 Connect the fiber-optic cable to the connector on the Fiber
Expansion Daughterboard as shown in Figure 14 on page 53.
Use of the fiber-optic interface product in the Option 11C is
considered safe. However, as a precaution, do not look directly at the
optical port or the end of fiber-optic cable. The optical port can cause
eye exposure beyond the limits of Maximum Permissible Exposure
recommended in some areas. For example, this condition can occur
during cable testing or under light magnification. Do not remove
protective caps or plugs until you are ready to connect the cable.
Use one of the following methods:
— If using the A0632902 (was the A0618443) cable:
a Remove the two protective plugs from the Fiber Expansion
Daughterboard.
b Connect the cable to the Fiber Expansion Daughterboard.
Make sure the V-shaped groove on the cable connector faces
outward and the connector seats tightly. The marking (if there
is one) on the connector is not visible when you connect the
cable correctly. See Figure 15 on page 54.
— If using glass fiber-optic cable:
a Remove the protective plug from the Fiber Expansion
Daughterboard. Remove the protective cap from the
corresponding plug (Tx or Rx) on the glass fiber-optic cable.
b Insert the plug in its assigned connector on the daughterboard.
c Lock the connector in position by turning it a half turn
clockwise. See Figure 16 on page 54.
d Repeat these steps for the second fiber-optic connection.
