ML1000-2 Card-Level Indicators

 

 

Card-Level LEDs

Description

 

 

FAIL LED (Red)

The red FAIL LED indicates that the card’s 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)

A 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.

 

 

 

5.7.2 ML1000-2 Port-Level Indicators

The ML1000-2 card has two LEDs for each of the two Gigabit Ethernet ports. The port-level indicators are described in Table 5-14.

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.

 

 

5.7.3 ML1000-2 Slot Compatibility

The ML1000-2 card works in Slots 1 to 6 or 12 to 17.

5.8 GBICs and SFPs

This section describes the GBICs and SFPs used with the Ethernet cards.

The ONS 15454 SDH Ethernet cards use industry standard small form-factor pluggable connectors (SFPs) and Gigabit Interface Converter (GBIC) modular receptacles. The ML-Series Gigabit Ethernet cards use standard Cisco SFPs. The Gigabit E-Series card and the G-Series card use standard Cisco GBICs. With Software Release 4.1 and later, G-Series cards can also be equipped with dense wavelength division multiplexing (DWDM) and coarse wavelength division multiplexing (CWDM) GBICs to function as Gigabit Ethernet transponders.

For all Ethernet cards, the type of GBIC or SFP plugged into the card is displayed in CTC and TL1. Cisco offers SFPs and GBICs as separate orderable products.
