4.11.2 OC48 LR/STM16 LH AS 1550 Port-Level Indicators
You can find the status of the OC48 LR/STM16 LH AS 1550 card port by using the LCD screen on the
ONS 15454 fan-tray assembly. Use the LCD to view the status of any port or card slot; the screen
displays the number and severity of alarms for a given port or slot.
4.12 OC48 ELR/STM16 EH 100 GHz Cards
Note For hardware specifications, see the “A.6.11 OC48 ELR/STM 16 EH 100 GHz Card Specifications”
section on page A-34. See Table 4-2 on page 4-4 for optical card compatibility.
Thirty-seven distinct OC48 ELR/STM16 EH 100 GHz cards provide the ONS 15454 DWDM channel
plan. Each OC48 ELR/STM16 EH 100 GHz card has one SONET OC-48/SDH STM-16 port that
complies with Telcordia GR-253-CORE, ITU-T G.692, and ITU-T G.958.
The port operates at 2.49 Gbps over a single-mode fiber span. The card carries VT, concatenated
(STS-1), and nonconcatenated (STS-1, STS-3c, STS-6c, STS-12c, or STS-48c) payloads.
Warning
The laser is on when the optical card is booted. The port does not have to be in service for the laser
to be on.
Statement 293
Figure 4-11 shows the OC48 ELR/STM16 EH 100 GHz faceplate and a block diagram of the card.
Table 4-12 OC48 LR/STM16 LH AS 1550 Card-Level Indicators
Card-Level Indicators Description
Red FAIL LED The red FAIL LED indicates that the card’s processor is not ready. Replace
the card if the red FAIL LED persists.
Green/Amber ACT
LED
The green ACT LED indicates that the card is carrying traffic or is
traffic-ready. The amber ACT LED indicates that the card is part of an active
ring switch (BLSR).
Amber SF LED The amber SF LED indicates a signal failure or condition such as LOS, LOF,
or high BERs on the card’s port. The amber SF LED is also on if the transmit
and receive fibers are incorrectly connected. If the fibers are properly
connected, the light turns off.
