Identifying Bricks

144
Bricks are referenced by their racks and slot or unit locations. These values are stored in
non-volatile memory on the L1 controller. Virtually all system controller
communications require that each brick have a valid and unique rack and slot.
If a brick is not set with its rack and slot number, it appears in the output of an L2 config
command, as shown in the following example:
L2> config
137.38.88.82.1.0 ---c-- (no rack/slot set)
L2>
To set the rack and slot for a brick, address it by its IP address, USB port, and L1 controller
index. Note the following example:
L2> 137.38.88.82:1:0 brick rack 1
L2> 137.38.88.82:1:0 brick slot 11
L2> 137.38.88.82:1:0 reboot_l1
INFO: closed USB /dev/sgil1_0

L2>config
