Error IP Address lost

During start-up the expansion box beeps several times. The last beep

sequence indicates whether the default IP address (192.100.100.98)

stored in the Flash Disk is active (three short beeps) or if the IP address

has been changed by the user (one long beep).

The host and the expansion box cannot be connected via Ethernet if

the IP address of the expansion box is unknown.

➤ To find out the client’s IP address, connect a VGA monitor to the

slot CPU. The IP address is displayed during power-up. Use this

address to connect to the expansion box again.

Error Wrong IP address

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:

■ 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.

■ The IP address of each node must be unique within the network.

■ 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.

Error Wrong subnet mask

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.

Error Wrong cable

The supplied crossed-over patch cable can only be used for a

peer-to-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.
