7.8.7 40-DMX-CE Card Port-Level Indicators
You can find the alarm status of the 40-DMX-CE card ports using the LCD screen on the ONS 15454
fan-tray assembly. The screen displays the number and severity of alarms on a given port or slot. For the
procedure to view these counts, refer to the “Manage Alarms” chapter in the Cisco ONS 15454 DWDM
Procedure Guide.
7.9 40-MUX-C Card
Note See the “A.7.5 40-MUX-C Card Specifications” section on page A-29 for hardware specifications.
Note For 40-MUX-C card safety label information, see the “7.2 Safety Labels for Class 1M Laser Product
Cards” section on page 7-9.
The single-slot 40-Channel Multiplexer C-band (40-MUX-C) card multiplexes forty ITU-T
100-GHz-spaced channels identified in the channel plan in Table 7-21 on page 7-38. The 40-MUX-C
card can be installed in Slots 1 to 6 and 12 to 17. The 40-MUX-C card is typically used in hub nodes.
7.9.1 40-MUX-C Card Faceplate Ports
The 40-MUX-C card has two types of ports:
• COM TX port: COM TX is the line output port for the aggregate optical signal being multiplexed.
This port is supported by both a VOA for optical power regulation and a photodiode for per-channel
optical power monitoring.
Note By default, the VOA is set to its maximum attenuation for safety purposes (for example,
electrical power failure). A manual VOA setting is also available.
• DROP RX ports (1 to 40): The 40-MUX-C card provides 40 input optical channels. These ports are
connected using five physical receive connectors on the card’s front panel that accept MPO cables
for the client input interfaces. MPO cables break out into eight separate cables. The 40-DMX-C card
also has one LC-PC-II optical connector for the main output. For the wavelength range, see
Table 7-21 on page 7-38.
Green ACT LED The green ACT LED indicates that the 40-DMX-CE card is carrying traffic
or is traffic-ready.
Amber SF LED The amber SF LED indicates a signal failure on one or more of the card’s
ports. The amber SF LED also turns on when the transmit and receive fibers
are incorrectly connected. When the fibers are properly connected, the light
turns off.
