Model 2285 Getting Started Guide

ically configured on the DHCP server side, and each DHCP client computer receives this information when
the IP address is provided at its boot-up.
Each time the device is reset, the Model 2285 broadcasts a DHCP request over the network. The reply gener-
ated by the DHCP server contains the IP address, as well as the subnet mask, gateway address, DNS servers
and the “lease” time. The Model 2285 immediately places this information in its memory. Once the “lease”
expires, the Model 2285 will request a renewal of the “lease” time from the DHCP server. If the DHCP server
approves the request for renewal, the Model 2285 can continue to work with the current IP address. If the
DHCP server denies the request for renewal, the Model 2285 will start the procedure to request a new IP
address from the DHCP server.
Note
While in DHCP mode, all network-related parameters for the Model 2285
are to be configured automatically, including the DNS servers. If the DNS
server is not automatically configured, the user may manually configure the
settings by entering the primary and secondary DNS IP addresses. To force
an automatic configuration of the DNS address, set the primary and second-
ary DNS IP addresses to 0.0.0.0 (recommended).
A DHCP sever assigns IP addresses dynamically from an IP address pool, which is managed by the network
administrator. This means that the DHCP client, i.e. the Model 2285, receives a different IP address each time
it boots up. The IP address should be reserved on the DHCP server side to assure that the user always knows
the newly assigned Model 2285 address. In order to reserve the IP address in the DHCP network, the adminis-
trator needs the MAC address of the Model 2285 found on the label sticker at the bottom of the Model 2285.
