The IP addresses of expansion box and network, or expansion box
and host PC (for peer-to-peer connection) must adhere to the
following rules:
n
The network part of the IP address must be identical on both
systems. Only the workstation part may differ. For details, refer to
a definition of IP address classes.
n
The IP address of each node must be unique within the network.
n
The IP address must not be one of the reserved loopback
addresses 127.0.0.0 and 127.0.0.1. Additional restrictions may
apply.
Wrong IP address
The expansion box does not support subnetting. The subnet mask is
always adjusted automatically according to the selected IP address
class when changing the IP address using the
setip
utility. Zero subnet
bits are set.
Wrong subnet mask
The supplied crossed-over patch cable can only be used for a
peer

peer connection via Ethernet. It cannot be used to connect
the expansion box to an existing network.
Use a normal (non crossed-over) cable to integrate the expansion box
into an existing network.

then the BIOS setup might be missing and the expansion box will not
boot.
