About this task
The following figures show the I/O module slot numbers.
The slot labeled N is the network daughter card, which contains ports ethMa, ethMb, ethMc, and
ethMd.
The physical interface name format for the other I/O module slots is eth
Xy
, where X is the slot
number and
y
is an alphanumeric character. For example, eth0a.
For most horizontal I/O module NIC interfaces, the port numbering goes from left to right, with
eth
X
a on the left. The horizontal I/O module slots on the left-in slots 11-13 are inverted. The port
numbering on these I/O modules in these slots goes from right to left, with eth
X
a on the right.
For vertical I/O module NIC interfaces, the port numbering goes from top to bottom, with eth
X
a at
the top.
The management port ethMa is the first port set up by the Configuration Wizard. It is marked with
a red rectangle in the figure below.
