8.6.4 TXP_MR_2.5G and TXPP_MR_2.5G Card-Level Indicators
8.6.4 TXP_MR_2.5G and TXPP_MR_2.5G Card-Level Indicators
Table 8-11 lists the three card-level LEDs on the TXP_MR_2.5G and TXPP_MR_2.5G cards.
8.6.5 TXP_MR_2.5G and TXPP_MR_2.5G Port-Level Indicators
Table 8-12 lists the four port-level LEDs on the TXP_MR_2.5G and TXPP_MR_2.5G cards.
8.7 MXP_2.5G_10G Card
The MXP_2.5G_10G card multiplexes/demultiplexes four 2.5-Gbps signals (client side) into one
10-Gbps, 100-GHz DWDM signal (trunk side). It provides one extended long-range STM-64/OC-192
port per card on the trunk side (compliant with ITU-T G.707, ITU-T G.709, ITU-T G.957, and Telcordia
GR-253-CORE) and four intermediate- or short-range OC-48/STM-16 ports per card on the client side.
The port operates at 9.95328 Gbps over unamplified distances up to 80 km (50 miles) with different types
of fiber such as C-SMF or dispersion compensated fiber limited by loss and/or dispersion.
Client ports on the MXP_2.5G_10G card are also interoperable with SONET OC-1 (STS-1) fiber optic
signals defined in Telcordia GR-253-CORE. An OC-1 signal is the equivalent of one DS-3 channel
transmitted across optical fiber. OC-1 is primarily used for trunk interfaces to phone switches in the
United States. There is no SDH equivalent for SONET OC-1.
Table 8-11 TXP_MR_2.5G and TXPP_MR_2.5G Card-Level Indicators
Card-Level LED Description
Red FAIL LED The red FAIL LED indicates that the card’s processor is not ready. This LED
is on during reset. The FAIL LED flashes during the boot process. Replace
the card if the red FAIL LED persists.
ACT/STBY LED
Green (Active)
Amber (Standby)
If the ACT/STBY LED is green, the card is operational (one or both ports
active) and ready to carry traffic. If the ACT/STBY LED is amber, the card
is operational and in standby (protect) mode.
Amber SF LED The amber SF LED indicates a signal failure or condition such as LOS, LOF,
or high BERs on one or more of the card’s ports. The amber SF LED is also
on if the transmit and receive fibers are incorrectly connected. If the fibers
are properly connected and the link is working, the light turns off.
Table 8-12 TXP_MR_2.5G and TXPP_MR_2.5G Port-Level Indicators
Port-Level LED Description
Green Client LED The green Client LED indicates that the client port is in service and that it is
receiving a recognized signal.
Green DWDM LED
(TXP_MR_2.5G only)
The green DWDM LED indicates that the DWDM port is in service and that
it is receiving a recognized signal.
Green DWDM A LED
(TXPP_MR_2.5G only)
The green DWDM A LED indicates that the DWDM A port is in service and
that it is receiving a recognized signal.
Green DWDM B LED
(TXPP_MR_2.5G only)
The green DWDM B LED indicates that the DWDM B port is in service and
that it is receiving a recognized signal.
