Switched Rack PDU

USER’S GUIDE

®

Rack PDU will add this domain name when only a hostname is entered.

To override the expansion of a specified host name by the addition of the domain name, do one of the following:

• To override the behavior in all instances, set the domain name field in Configure General Settings to

its default somedomain.com or to 0.0.0.0.

To override the behavior for a particular host name entry — for example when defining a trap receiver — include a trailing period. The Switched Rack PDU recognizes a host name with a trailing period (such as mySnmpServer.) as if it were a fully qualified domain name and therefore does not append the domain name.

A Port Speed setting is available for all Boot mode selections to define the TCP/IP port’s communication speed (Auto-negotiate, by default).

Three settings are available for all Boot mode selections, except Manual, to identify the Rack PDU in BOOTP or DHCP communication:

Vendor Class: Uses APC, by default.

Client ID: Uses the Rack PDU’s MAC address, by default.

If the Client ID is changed from the Rack PDU’s MAC address, the new value must be unique on the LAN.

Caution Otherwise, the DHCP or BOOTP server may act incorrectly.

User Class: Uses the Rack PDU’s application module type, by default.

Two settings are available if BOOTP only is the Boot mode selection:

Retry Then Fail: Defines how many times the Rack PDU will attempt to discover a BOOTP server before it stops (4, by default).
