Setting Up for Network Communications
The CRD2700-4000E cradle allows communication between
terminals and their associated host computers connected to an
Ethernet network. The CRD2700-4000E must be connected to an
Ethernet network which is connected to the same network as the
host computers, or an Ethernet network connected to the larger
Internet via an Internet gateway. There are two methods to
accomplish this: DHCP mode and Static mode.
DHCP Mode
1 DHCP Address Mode
When using DHCP mode, the cradle acquires its IP address
dynamically from the server. There must be a DHCP server or a
DHCP relay agent on the same subnet as the CRD2700-4000E for
the unit to be automatically configured with IP addresses, a
gateway IP address, 2 DNS addresses, at least one WINS server
address, and a subnet mask. The cradle acquires 6 IP addresses
from the DHCP server. These addresses are allocated as follows:
one for the cradle, one for the expansion port, and one for each
slot (4).
Caution:
For the cradle to work properly in DHCP mode, it must
acquire 6 addresses from the DHCP server by request-
ing addresses with different requestor IDs. Some
DHCP servers will not use this, and will use the MAC
address. In this case the cradle only receives one ad-
dress and will not operate, which has happened on
some Novell servers. In this case, use static mode.
To set up for network communications:
1. Ensure there is a DHCP server accessible to the CRD2700-
4000E on the subnet.
