Chapter 5 Ethernet Cards
5.6.2 ML100T-12 Port-Level Indicators
5.6.2 ML100T-12 Port-Level Indicators
The ML100T-12 card provides a pair of LEDs for each Fast Ethernet port: an amber LED for activity
(ACT) and a green LED for LINK. The port-level indicators are described in Table 5-12.
5.6.3 ML100T-12 Slot Compatibility
The ML100T-12 card works in Slots 1 to 6 or 12 to 17.
5.7 ML1000-2 Card
The ML1000-2 card provides two ports of IEEE-compliant, 1000-Mbps interfaces. Each interface
supports full-duplex operation for a maximum bandwidth of 2 Gbps per port and 4 Gbps per card. Each
port autoconfigures for full duplex and IEEE 802.3x flow control.
SFP modules are offered as separate orderable products for maximum customer flexibility. For details,
see the “5.8 GBICs and SFPs” section on page 5-14.
Table 5-11 ML100T-12 Card-Level Indicators
Card-Level LEDs Description
Red SF LED The red SF LED indicates that the card’s processor is not ready or that a
catastrophic software failure occurred on the ML100T-12 card. As part of the
boot sequence, the FAIL LED is illuminated until the software deems the
card operational.
Green ACT LED A green ACT LED provides the operational status of the ML100T-12. If the
ACT LED is green, it indicates that the ML100T-12 card is active and the
software is operational.
Table 5-12 ML100T-12 Port-Level Indicators
Port-Level LED State Description
ACT LED (Amber) Steady amber LED indicates that a link is detected, but there is an
issue inhibiting traffic.
Blinking amber LED means that traffic is flowing.
LINK LED (Green) Steady green LED indicates that a link is detected, but there is no
traffic.
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.
