Figure 3-2. ARN Power Switch
To power on an ARN, press the power switch to the ON position (1). Verify that
air is flowing by placing your hand next to the fan vents. If you cannot feel air
flowing from the vents, and either the Pwr and Fail LEDs do not light or the Fail
LED remains on, turn the power switch to the OFF position. Wait one minute and
then turn the power switch to the ON position.
If the ARN does not turn on, check the power cable connections. See “Connecting
the Power Cable” on page 1-29 for information. If the ARN will not power on,
contact the Nortel Networks Technical Solutions Center.
To power off the ARN, press the power switch to the OFF position (0).
Note: To ensure a complete power cycle, you should wait at least 4 seconds
between powering off the ARN and powering it back on.
Caution: Cycling power to the ARN too quickly could cause an error.
