set to 255.255.255.0 by default. This part of the destination IP address is used along with the ATLAS 550

IP address to determine which nodes must be reached through the default IP gateway.

SYSTEM CONFIG > ETHERNET PORT > MAC ADDRESS
Read security: 5

Displays the system Ethernet Media Access Control (MAC) address. This field is read-only.

SYSTEM CONFIG > ETHERNET PORT > ETHERNET SPEED
Write security: 2; Read security: 5

Defines the rate at which the ETHERNET port operates. Choose from 10 MBPS or AUTO 10/100. When the

unit is set for AUTO 10/100, the ATLAS 550 auto-detects the data rate of the LAN and sets itself to that rate,

either 10 or 100 Mbps.

SYSTEM CONFIG > ETHERNET PORT > DHCP STATUS
Read security: 5

Displays the current status of the DHCP client in the ATLAS 550. The following states are possible (per

RFC 2131): INIT, SELECTING, REQUESTING, BOUND, RENEWING, REBINDING, INIT-REBOOT, REBOOTING, and

NON-INIT.
SYSTEM CONFIG > ETHERNET PORT > LEASE EXPIRES
Read security: 5

Displays the date and time the current IP address lease will expire and a new one will be necessary.

SYSTEM CONFIG > ETHERNET PORT > RELEASE
Write security: 2; Read security: 5

Forces the ATLAS 550 to release the currently assigned IP address.

SYSTEM CONFIG > ETHERNET PORT > RENEW
Write security: 2; Read security: 5

Forces the ATLAS 550 to send a message to the DHCP server requesting a new IP address lease.

SYSTEM CONFIG > CHAIN PORT
Write security: 2; Read security: 5

Accepts input for configuring the CONTROL IN (Chain) port located on the rear of the unit.

Once the IP address is manually released, the ATLAS 550 will not be available for Telnet

access until a manual renew is performed.
