CHAPTER 4: Operation
4.2 Basic Operating Instructions and Indications
Once you install and configure the FradSwitch A/S 3 Port, it normally operates
unattended. After initial setup, operator intervention is only required when the
Switch has to be reconfigured or if something goes wrong. Note that the Switch
stores its configuration in nonvolatile RAM (NVRAM), so it won’t lose its
configuration if it loses power.

The FradSwitch A/S 3 Port will begin operating as soon as you attach its power
cord to its rear-panel power inlet and plug the cord into AC power; the Switch has
no ON/OFF switch. The Switch’s PWR LED should light and some or all of its
other LEDs should flash. (Which other LEDs flash might depend on how the
Switch is configured.) If the ERR, OVF, or TEST LEDs light, make sure that after a
short interval (during which the Switch performs its power-up self-test) the LED
goes dark again.

PERATION
During normal operation, the PWR and SYNC LEDs should be continuously lit and
the TEST, OVF, and ERR indicators should remain dark. Channel- and link-activity
LEDs should flash according to the traffic load, and should be dark when the
channel is idle.
