• Renewal Time, T1 (option 58): The time that the Main Module must wait after an IP

address lease is assigned before it can request a renewal of that lease.

• Rebinding Time, T2 (option 59): The time that the Main Module must wait after an IP

address lease is assigned before it can seek to rebind that lease.

Other options. The Main Module also uses the following options within a valid DHCP

response. All of these options except the last are described in RFC2132.

• Network Time Protocol Servers (option 42): Up to two NTP servers (primary and

secondary) that the Main Module can use.

• Time Offset (option 2): The offset of the Main Module's subnet, in seconds, from

Coordinated Universal Time (UTC).

• Domain Name Server (option 6): Up to two Domain Name System (DNS) servers

(primary and secondary) that the Main Module can use.

• Host Name (option 12): The host name that the Main Module will use (32-character

maximum length).

• Domain Name (option 15): The domain name that the Main Module will use

(64-character maximum length).

• Boot File Name (from the file field of the DHCP response, described in RFC2131):

The fully qualified directory-path to an APC user configuration file (.ini file) to

download. The siaddr field of the DHCP response specifies the IP address of the

server from which the Main Module will download the .ini file. After the download,

the Main Module uses the .ini file as a boot file to reconfigure its settings.

Port Speed (Administration>Network>Port Speed)

The Port Speed setting defines the communication speed of the TCP/IP port.

•For Auto-negotiation (the default), Ethernet devices negotiate to transmit at the

highest possible speed, but if the supported speeds of two devices are unmatched,

the slower speed is used.

• Alternatively, you can choose either 10 Mbps or 100 Mbps, each with the option of

half-duplex (for communication in only one direction at a time) or full-duplex (for

communication simultaneously in both directions on the same channel).
