Hardware Reference 41
C613-03023-00 REV P
The first part of the display shows details of cards installed in the switch or
router. There should be one entry for the switch or router base card and one
entry for each PIC installed. Both the serial number and the part name should
also be displayed.
If there is no entry for a PIC, then the boot process has not correctly detected
the presence of the PIC. The most likely causes are:
■ The connector on the PIC is not plugged into the PIC slot on the base card
correctly.
Repeat the installation process, inserting the PIC carefully into the lowest
numbered free bay, then tightening the screws firmly. Use the show system
command again to check that the PIC has been recognised.
■ The software version running on the switch or router does not support the
PIC. The AT-AR021 V3 hardware revision requires Software Version
2.9.1-13 or later. Use the show system command to check the software
version.
For more information about the show system command, see the Operation
chapter of the AlliedWare
®
Operating System Software Reference for your switch
or router.
If the display is still not correct, contact your authorised Allied Telesis

Using a terminal to verify operation
PICs with asynchronous ports can be tested using a terminal set to:
■ 9600 bps
■ 8 data bits
■ 1 stop bit
■ No parity
■ Hardware flow control
Verify that the terminal functions correctly by connecting it to the management
port (Console Port or RS-232 Terminal Port) on your switch or router and
pressing
[Return] several times until the prompt is displayed.
Then connect the terminal to one of the PIC’s ports, and press
[Return] several
times. If the prompt is displayed, the port is functioning correctly. If the prompt
is not displayed, the most likely cause is that the PIC’s ports are set to different
operational parameters. This can be verified by reconnecting the terminal to
the management port and then using the command:
show port=all
Compare the PIC’s port settings with the settings for the management port.
Any differences should be corrected by modifying the settings of the ports on
the PIC using the set asyn command from the Interfaces chapter of the
AlliedWare
®
Operating System Software Reference for your switch or router.
Reconnect the terminal to one of the PIC’s ports and press
[Return] several
times. If the prompt is still not displayed, contact your authorised Allied Telesis
distributor or reseller.
