Switched Rack PDU
65
DNS serversThe Rack PDU cannot send any e-mail messages unless the IP address of
the primary DNS server is defined.
The Rack PDU will wait a maximum of 15 seconds for a response from the
primary or (if specified) the secondary DNS server. If the 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 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 settingsThe Email option in the Network menu accesses the following settings:
Email RecipientsSee DNS.
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 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.
