5.10.2 ML1000-2 Port-Level Indicators

The ML1000-2 card has three LEDs for each of the two Gigabit Et hernet ports, described in Table 5-20.

5.10.3 Cross-Connect and Slot Compatibility

The ML1000-2 card is compatible in Slots 1 to 6 or 12 to 17 with the XC10G or XC-VXC-10G card. It
is only compatible in Slots 5, 6, 12, or 13 with the XCVT card.
5.11 ML-MR-10 Card
Note For hardware specifications, see the “A.7.12 ML-MR-10 Card Specifications” section on page A-52.
The ML-MR-10 card is a ten-port multilayer Ethernet card. The Ethernet ports support speeds of
10 Mbps, 100 Mbps, or 1000 Mbps through pluggable SFPs. SFP modules are offered as separate
orderable products for flexibility. For details, see the “5.15 Ethernet Card GBICs and SFPs” section on
page 5-36.
The ML-MR-10 card supports a resilient packet ring (RPR) interface. RPR uses two POS like inte rfaces
to terminate the SONET circuits. The circuit sizes supported on t he RPR interfaces are STS-12c, STS
-24c, STS- 48c, and STS -96c. A maximum aggregate of OC-192 of bandwidth can terminat e on a single
card. The RPR interface on ML-MR-10 supports only framed generic framing procedure (GFP-F)
encapsulation for SONET.

Card-Level LEDs Description
SF LED (Red) The red FAIL LED indicates that the card processor is not ready or that a
catastrophic software failure occurred on the ML1000-2 card. As part of the
boot sequence, the FAIL LED is turned on until the software deems the card
operational.
ACT LED (Green) The green ACT LED provides the operational status of the ML1000-2. When
the ACT LED is green, it indicates that the ML1000-2 card is active and the
software is operational.
Table 5-20 ML1000-2 Port-Level Indicators
Port-Level Indicators Description
ACT LED (Amber) A steady amber LED indicates a link is detected, but there is an issue
inhibiting traffic. A blinking amber LED means traffic flowing.
LINK LED (Green) A steady green LED indicates that a link is detected, but there is no
traffic. A blinking green LED flashes at a rate proportional to the level
of traffic being received and transmitted over the port.
Both ACT and LINK LED Unlit green and amber LEDs indicate no traffic.
