DNS
From the Domain Name Server (DNS) settings menu, an administrator can configure the servers the
RPC2 communications module will use for hostname resolution. When configured, host addresses for
SNMP, Network Time and Email/SMS can be specified in either full Domain Name format or host-
only format, provided that the appropriate Domain Name Suffix is used.
The DNS menu is used to set parameters for network access to the RPC card. Consult your network
administrator for these settings.
To configure DNS Server settings:
1. Log in with the privileges required to change these settings.
2. From the side navigation bar of the System tab, click Network>DNS.
3. Select whether to obtain DNS server addresses automatically or to enter them manually.
4. If they will not be obtained automatically, enter the primary and secondary DNS addresses.
5. Use the drop-down menu to select in hours how long the RPC2 communications module retains
resolved addresses.
6. Enter the Domain Name Suffix. This suffix is used for assembling a fully qualified domain name
when a host-only name is specified.
7. Click the Save icon when finished.
DNS Test
The DNS Test function checks whether the RPC2 communications module will resolve a hostname to
an IP address.
To run a DNS test:
1. Log in with the privileges required to change these settings.
2. From the side navigation bar of the System tab, click Network>DNS.
3. Under the DNS Test heading, use the drop-down menu to select a fully qualified domain name or
an IP address.
4. In the Question field, enter a value for the DNS to answer.
5. Click the Query icon at the top of the page to attempt a lookup with the provided information.
Time (SNTP)
The RPC2 communications module provides two options for setting the date and time. It can retrieve
the date and time from a simple network time protocol (NTP) server, or the date and time can be set
manually so that the rack PDU’s internal clock is used to provide time and date information.
To set the date and time:
1. Log in with the privileges required to change these settings.
2. From the side navigation bar of the System tab, click Network.
3. Under the SNTP heading, select NTP Server to use a NTP server.
-or- Select Local to manually set the date and time.
4. If using NTP, enter an NTP server site in the Time Server field.
5. Select either Hourly or Daily for the synchronize rate.
6. Use the drop-down menu to select the time zone.
7. If manually setting the date and time, enter the time in YYYY-MM-DD HH:MM:SS format in the
System Date and Time field.
8. Click the Save icon, ✔..
NOTE
To re-sync the time immediately, click the Sync Time Now icon at the top of the page.
