7.11.7 40-WSS-CE Card Port-Level Indicators
You can find the alarm status of the 40-WSS-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.
7.12 40-WXC-C Card
Note See the “A.7.10 40-WXC-C Card Specifications” section on page A-36 or hardware specifications.
Note For 40-WXC-C safety label information, see the “7.2 Safety Labels for Class 1M Laser Product Cards”
section on page 7-9.
The double-slot 40-channel Wavelength Cross-Connect C Band (40-WXC-C) card selectively sends any
wavelength combination coming from nine input ports to a common output port. The device can manage
up to 41 channels spaced at 100GHz on each port according to the channel grid in Table 7-6 on page 7-7.
Each channel can be selected from any input. The card is optically passive and provides bidirectional
capability. It can be installed in Slots 1 to 6 and 12 to 17.
.The 40-WXC-C card provides the following features:
• Demultiplexing, selection, and multiplexing of DWDM aggregate signal from input ports to
common output port.
• Aggregate DWDM signal monitoring and control through a VOA.
• VOAs are deployed in every channel path in order to regulate the channel’s optical power. In the case
of an electrical power failure, VOAs are set to their maximum attenuation value, or to a fixed and
configurable one. The VOA can also be set manually.
• Per-channel optical power monitoring using photodiodes.
The 40-WXC-C card acts as a selector element with the following characteristics:
• It is able to select a wavelength from one input port and pass the wavelength through to the common
out port. Simultaneously, the card can block the same wavelength coming from the other eight input
ports.
• It is able to stop wavelengths from all nine inputs.
Green ACT LED The green ACT LED indicates that the 40-WSS-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.
