Tips At startup of the server, if the ExpEther board detects the ExpEther IO
Expansion Unit that has the same Group ID as this board itself, it connects the
I/O device to the server. The connected I/O device is recognized, by the OS, as
a PCI device.
If there are two or more ExpEther IO Expansion Units that have the same Group
ID, the ExpEther board connects the devices based on the order in which it
detected the Expansion Units. Therefore, the order of the PCI devices
recognized by the OS may vary, depending on the order in which ExpEther
board detected the Expansion Units.
If you have installed ExpEther Manager, it specifies for the ExpEther board, the
order of detecting the ExpEther I/O Expansion Units; thus, the I/O device can be
connected to the server in the same order each time the server starts up.
Tips The above order (specified by ExpEther Manager) of detecting the ExpEther IO
Expansion Units (40G) is recorded in the nonvolatile memory of the ExpEther
board (40G). Up to four I/O device slots can be connected to the ExpEther
board (40G). Therefore, to connect a new I/O device to an ExpEther board
(40G) to which four I/O device has been connected, use the following procedure
for connection:
1. Disconnect the I/O device to which the connection is to be suspended. Then
start up the server.
2. Execute CLI subcommand del_iomac to delete the target I/O device
information.
3. Connect the new I/O device to the ExpEther board (40G).
