Chapter 3: AT-MCF2012LC, AT-MCF2012LC/1 and AT-MCF2032SP Modules

50 Section I: Features

HBI and HBO

Heartbeat LEDs

The AT-MCF2032SP Module has two heartbeat LEDs labeled HBI and

HBO. If the chassis has a management or stacking module, the LEDs

flash as the media converter module transmits or receives packets over

the backplane in the chassis.

Channel LEDs The modules have channel LEDs that are used together with the Mode

button to change the operating modes of the channels and to view duplex

modes and collisions. The channel LEDs on the AT-MCF2012LC/1 Media

Converter Modules are located below the fiber optic ports and are labeled

“CH.” The channel LEDs on the AT-MCF2012LC Module are the number

row of LEDs below the SFP slots. For more information on these LEDs,

refer to “Mode Button” on page 51.

Steady Amber The module is storing a new version of its

management software in flash memory.

Caution

Do not power off the chassis or remove the

module when the LED is amber. Doing so

may damage the module.
