You can find the alarm status of the 40-WSS-C 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.
7.11 40-WSS-CE Card
Note See the “A.7.9 40-WSS-CE Card Specifications” section on page A-33 for hardware specifications.
Note For 40-WSS-CE card afety 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 Selective Switch Even-Channel C-Band (40-WSS-CE) card
switches 40 ITU-T 100-GHz-spaced channels identified in the channel plan (Table 7-35 on page 7-61)
and sends them to dedicated output ports. The 40-WSS-CE card is bidirectional and optically passive.
The card can be installed in Slots 1 to 6 and 12 to 17.
The 40-WSS-CE features include:
• Receipt of an aggregate DWDM signal into 40 output optical channels from the Line receive port
(EXP RX) in one direction and from the COM-RX port in the other direction.
• Per-channel optical power monitoring using photodiodes.
• Signal splitting in a 70-to-30 percent ratio, sent to the 40-DMX-CE card for dropping signals, then
to the other 40-WSS-CE card.
• Aggregate DWDM signal monitoring and control through a VOA. In the case of electrical power
failure, the VOA is set to its maximum attenuation for safety purposes. A manual VOA setting is
also available.
Within the 40-WSS-CE card, the first AWG opens the spectrum and each wavelength is directed to one
of the ports of a 1x2 optical switch. The same wavelength can be passed through or stopped. If the
pass-through wavelength is stopped, a new channel can be added at the ADD port. The card’s second
AWG multiplexes all of the wavelengths, and the aggregate signal is output through the COM-TX port.
Green ACT LED The green ACT LED indicates that the 40-WSS-C 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.
