4 • Operation and shutdown Model 3125 RAS Getting Started Guide
60 Introduction
Introduction
This chapter describes how to start or power-down the RAS.
Activating the RAS
Power to the modules is delivered from the cPCI chassis backplane through the 47-pin PICMG 2.11 power
connectors on the 3125RC. Upon insertion in the cPCI chassis, the Model 3125 immediately powers up and
begins its boot cycle. During the boot cycle, the following occurs on the 3125RC Resource Card:
1. The POWER LED illuminates, indicating normal power is being applied to the Model 3125.
2. The SYSTEM LED begins flashing, indicating the Model 3125 is operating normally.
On the 3125TM Transition Module, the following occurs after power is applied:
1. The Link 1 Frame LED illuminates, indicating that the RAS is synchronizing with the T1/E1/PRI signal.
2. After 5 seconds, the Link A Error LED flashes, indicating that the RAS is satisfied with the quality of the
T1/E1/PRI signal.
3. 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.
4. 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 Model 3125 RAS is operational.
De-activating the RAS
To power-down the 3125 RAS, either remove power from the cPCI rack in which the RAS is installed, or do
the following to remove the 3125RC Resource Card and/or 3125TM Transition Module from the cPCI rack:
Note Be sure to wear the anti-static strap to prevent electrostatic damage to
the module.
1. Use a Phillips screwdriver to loosen the captive fasteners on the 3125RC (see figure 11 on page 30) until
the fasteners no longer attach the module to the rack.
2. Press the red tab on each injection/ejection handle to release the handles (see figure 7 on page 28).
3. Slide the module from the rack and place it in an anti-static bag.
4. At the 3125TM Transition Module, disconnect and label the network cables from the module.
