ACT

Green

On indicates the card is active.

 

 

 

STBY

Yellow

• Slow blink without active LED indicates the card is in the boot

 

 

state.

 

 

• Fast blink with active LED indicates the ASC is downloading to

 

 

another card or is being downloaded.

 

 

• Steady yellow indicates the card is in standby state. The

 

 

firmware is executing ADMIN code.

 

 

 

FAIL

Red

• Steady red with active and standby LEDs off indicates the card

 

 

is in the reset condition, the card has failed, or the card set is not

 

 

complete (no line module).

 

 

• Steady red with active LED on indicates the card was active

 

 

prior to failing.

 

 

• Steady red with standby LED on indicates the card was in

 

 

standby prior to failing.

 

 

• Blinking red indicates the card is in the power up state.

 

 

 

LAN

Green

On indicates receive activity through the LAN port. A green flash is

 

 

seen for every packet received.

 

 

 

Auto Card Restore

Auto card restore is a feature that allows a service module card to be removed and be hot plug replaced with another service module card, keeping the same configuration. With this feature, the ASC maintains a copy of the configuration for each active service module.

Broadband Network Modules

The BNM card set provides the Cisco MGX 8220 trunk interface to a Cisco BPX 8600 series node. There are two major types of BNMs, one supports a T3 or E3 trunk and one supports a 155 Mbps SONET SMF trunk.

Each Cisco MGX 8220 shelf must be equipped with at least one BNM installed in slot 1 or slot 2. A second, redundant BNM can also be installed in slot 1 or slot 2. The primary and the redundant BNMs must be of the same type. Each BNM installed consists of a front and back card set.

In addition, the BNM provides

•External alarm interface

•Fan monitor interface

•Port for accepting an external T1 or E1 clock source
