DNS servers

The Switched Rack PDU cannot send any e-mail messages unless the IP

address of the primary DNS server is defined (see DNS servers).

The Switched Rack PDU will wait a maximum of 15 seconds for a response

from the primary or (if specified) the secondary DNS server. If the Switched

Rack PDU does not receive a response within that time, e-mail cannot be

sent. Therefore, use DNS servers that are on the same segment as the

Switched Rack PDU or on a nearby segment (but not across a WAN).

Once you define the IP addresses of the DNS servers, verify that DNS is

working correctly. Enter the DNS name of a computer on your network to

test whether you can look up the IP address for that DNS name.

SMTP settings

The Email option in the Network menu accesses the following settings:

Setting Description

SMTP Server

Defines the SMTP server by its DNS name.

Note: This definition is required only when the SMTP Server option

(see Email Recipients) is set to Local.

From Address

Defines the contents of the From field in the e-mail messages sent

by the Switched Rack PDU.

Note: The SMTP server’s configuration may require that you use a

valid user account on the server for this setting. See the

server’s documentation for more information.
