Description

1

OFL button

-

If there are at least two SFUs installed and running properly, before removing one SFU, hold down the OFL button on the SFU until the OFL indicator blinks red or turns steady red. When the OFL indicator turns steady red indicating that the SFU is isolated from the system, you can remove the SFU. When an SFU is running normally, its RUN/ALM indicator blinks green slowly and its OFL indicator is off.

2

OFL indicator

Red

Steady on: The SFU has been separated from the system and can be removed from the chassis.

Blinking: The SFU is being separated from the system and cannot be removed from the chassis.

Off: The SFU is running properly and cannot be removed from the chassis.

3

RUN/ALM: running status indicator

Green

Steady on: The card has been powered on, but the software is not running.

Slow blinking: The card software is running properly.

Fast blinking: The card software is starting.

Red
