Verifying that the ATM adapter is installed and functioning

Verifying that the adapter works

To verify that the ATM adapter is functioning, complete the following step.

Step	Action
1	Enter the following command: `atm adinfo` You can perform the `atm adinfo` command again at any time to determine the correct unit number.

Example of the atm adinfo command

Sample output from the adinfo command is as follows:

atm adinfo

a1:unit 1:      PCA-200E Media=OC3-MM-SC HW=2.0.1 FW=4.2.0 
Serial=4201600 Slot=1

        MAC=00:20:48:40:1C:80

a2:unit 2:      PCA-200E Media=OC3-MM-SC HW=2.0.1 FW=4.2.0 
Serial=4201621 Slot=2

        MAC=00:20:48:40:1C:95

a3:unit 3:      PCA-200E Media=OC3-MM-SC HW=2.0.1 FW=4.2.0 
Serial=4201955 Slot=3

        MAC=00:20:48:40:1D:E3

Interpreting the output

You should see lines for each ATM adapter in your storage system that is functioning properly. The presence of the lines indicates that the adapter has passed its self-test procedure and that your storage system initialized the adapter. The adinfo command also displays the device name for each of the installed adapters, as well as the unit number, at the beginning of each line.

The unit number uniquely identifies the ATM adapter in your storage system, and there is a one-to-one mapping between the device names and unit numbers. The device name consists of the prefix "a" followed by the physical slot number. The unit number is the slot number.
