Chapter 12 – Adding an expansion cabinet
The fiber optic interface product used in the Option 11C Compact
system is considered safe. However, as a precaution do not view the
optical port or the end of fiber optic cable. Under certain conditions
(such as during cable testing or under light magnification) the cable or
port may expose the eye beyond the limits of Maximum Permissible
Exposure recommended in some jurisdictions. Do not remove
protective caps or plugs until ready to connect the cable.
14 Connect the fiber optic cable to the Fiber Expansion
Daughterboard on the NTMW01 SSC card as shown in
on page 104.
Remove the two protective plugs from the connectors on the Fiber
Expansion Daughterboard.
Connect the fiber optic cable to the Fiber Expansion Daughterboard
making sure that the 'V' shaped groove on the cable connector is
facing outward and that the connector is fully seated. The mark (if
equipped) on the connector should not be visible when properly
connected. See
15 Insert the NTMW01 SSC card in the CPU slot of the main cabinet.
16 Set the circuit breaker on the power supply in main cabinet to ON.
The Option 11C Compact system reloads (SYSLOAD) and service is
restored.
Check the fiber related LEDs on the SSC card.
• The LED for the Expansion Daughterboard should be green.
• If it is red (disabled indication);
Load overlay program 135 and enter ENL FL1 to enable
expansion cabinet.
• If the LED is yellow (fault indication):
Check the fiber optic cable to make sure that it is properly
connected and not damaged.
Check system time and date using LD 2. Reset if required.
