5.6.2 ML100T-12 Port-Level Indicators

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.

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.

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.

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.
