5.12 Setting the default gateway
The MDX-ETHERNET default gateway is formed by taking the component parts of the
default gateway from parameters Pr 15.68 to Pr 15.71 and combining them as in Figure
5-4. The default gateway is then used in conjunction with the IP address and subnet
mask to locate hosts on different subnets. Gateway address modification is activated by
resetting the MDX-ETHERNET (Pr 15.32 = ENABLED).
Figure 5-4 The default gateway
The default gateway is a routing device that allows a host to reach other devices that
are not on the same subnet. The default gateway must be on the same subnet as the
host that is trying to use it.
5.12.1 MDX-ETHERNET IP default gateway Wgateway
IP default gateway Wgateway
This is the most significant octet of MDX-ETHERNET IP default gateway address.
When using DHCP this will be updated from the DHCP server.
5.12.2 MDX-ETHERNET IP default gateway Xgateway
IP default gateway Xgateway
This is the second most significant octet MDX-ETHERNET IP default gateway address.
When using DHCP this will be updated from the DHCP server.
5.12.3 MDX-ETHERNET IP default gateway Ygateway
IP default gateway Ygateway
This is the third most significant octet of MDX-ETHERNET IP default gateway address.
When using DHCP this will be updated from the DHCP server.

When DHCP is enabled the whole default gateway address is acquired from the DHCP
server and written to the parameters in the drive during start-up. This could take several
minutes depending on server availability.
When communication is performed through a gateway, the devices on both sides of the
gateway must be configured to see their side of the gateway for communications to be
established.
