Figure 7 Instant Internet 400-S unit LEDs

LEDs 1 through 8 and Power LED at power-up sequence

If a failure occurs during the power-up sequence, the Power LED glows amber,

and one or more of LEDs 1 through 8 glow red. This sequence indicates a

hardware problem. Call the Nortel Networks Technical Solutions Center

(page 23) for assistance.

If all LEDs glow amber, or none of the LEDs illuminates, check that the power

voltage selector switch setting matches your power voltage. For more

information, see “Setting the voltage selector switch” on page 42.

Caution: During normal operation, the Power LED glows green, except

when updating the internal flash ROM. While updating the flash memory,

the Power LED glows amber. This amber LED indicates that it is not safe

to turn off the unit without potentially damaging the contents of flash

memory.
