Enabling Network Time Servers; Installing The S8500 Service Pack, If Any - Avaya S8500 Installing And Configuring

Enabling Network Time Servers

!
Important:
Avaya strongly recommends enabling Network TIme Protocol (NTP) and
Important:
configuring at least one network time server. If a network time server is not used,
the Date/Time settings on the media server should be reset regularly (at least
monthly), using the Maintenance Web Interface. The network time strategy
should be determined by the network administrator.
Enabling Network Time Protocol allows you to specify one, two, or three network time servers to
provide accurate time-of-day data to the clocks on the media servers. The network time servers,
in turn, get their source timing from one of several available, highly accurate, time services on
the Internet.
To use a network time server, the NTP service must be enabled. The Avaya Installation Wizard
prompts for enabling the NTP service.
If you are not using the Installation Wizard, or if you want to see if NTP is enabled, follow these
steps:
1. Open the Maintenance Web Interface
2. Click on the Firewall link under Security.
3. Enable ntp 123/udp in the "Output from Server" column by clicking on the checkbox.
Note:
It is not necessary to enable the "Input to Server" ntp service but if it is already
Note:
enabled, you don't have to disable it.
In the next section,
prompts for information about network time servers. When prompted, enter the DNS name or IP
address for the primary (and secondary and tertiary, if any) network time server. If you enter a
DNS name instead of an IP address for the network time server, the DNS server IP address
must be specified. You are prompted for this information by the Installation Wizard.
If you are not using the Installation Wizard, the network time servers can be configured using
the Configure Server function on the Maintenance Web Interface.
For detailed information about NTP, see RFC 958.

Installing the S8500 service pack, if any

If an S8500-specific service pack is required for SAMP use, install the service pack as
described in this section. The procedure in this section assumes that the service pack file has
been downloaded from the Avaya Support web site and copied to the S8500 media server.
Once initiated, the update process should take approximately 20 minutes.
