Introduction

This chapter describes how to start or power-down the RAS.

Activating the RAS

Once the RAS has been installed, no operator action is required under normal conditions; the RAS is designed for unattended operation. The RAS does not have a power switch. When either power supply is connected to power, the RAS will immediately begin its boot-up cycle. However, both power supplies must be connected to power for the redundancy feature to work.

When power is applied to the RAS the following should occur:

1.The POWER LED illuminates.

2.The Link 1 Frame LED illuminates, indicating that the RAS is synchronizing with the T1/E1/PRI signal.

3.After 5 seconds, the Link A Error LED flashes, indicating that the RAS is satisfied with the quality of the T1/E1/PRI signal.

4.After 10 seconds, the Link A Error LED extinguishes, indicating that the RAS is satisfied with the network signal and that the link is ready for use.

5.There are two LEDs on the RAS 10/100 Ethernet port: a green LED that indicates line speed, and a yellow LED that indicates link status and activity.

The yellow LED is either flashing yellow (meaning that packets are being received at the Ethernet port) or solid yellow (meaning that the link is valid but no packets are being received).

The green LED is either lit (indicating 100 Mbps operation) or off (indicating 10 Mbps operation).

Note The green LED reflects the speed of the last valid Ethernet connection.

The RAS is operational.

De-activating the RAS

Perform the following procedure to deactivate the RAS.

1.Disconnect the male ends of both power cords from the power distribution strip or to a wall outlet.

2.Verify that the POWER LED extinguishes.
