4: System Control
To see if the L2 is running (it will be if the LAN cable is plugged in and the cable is connected to
an active LAN).
At the L1 prompt type:
001c01-L1> l2
L2 Controller is running.
001c01-L1>
If the L2 is not running type:
001c01-L1> ! init 4
This switches the system controller to run level 4 and forces the L2 to be started whether or not
the LAN is plugged in. There is a space between the “!” and “init”
Verify the L2 is running again as above.
To set the IP address on the L2 type:
001c01-L1> l2 ip a.b.c.d 255.255.255.0 a.b.c.255
Verifying that the system serial number is set on the L2:
001c01-L1> l2 serial
To set the L2 system serial number:
001c01-L1> l2 serial set <serial number>
Verifying that
msys
is enabled (this allows multiple L2s in a system to exist peacefully with other
L2s from another system on the same subnet)
001c01-L1> l2 msys
If
msys
is off, turn it on:
001c01-L1> l2 msys on
Reboot the system controller to make the IP address change take effect.
001c01-L1> reboot_l1
Once this is done for all target IRUs and Dense routers, connect them to the network (using an
optional Ethernet switch if necessary).
The
rackid
on the L2 cannot be set with the L2 “
rackid
” command, instead it will be inherited
from the local L1. As an example: the L2 running on the system controller in 1r41 will have a rack
id of 141 (rack * 100 + slot of the local L1).
