n Check that LAN1 is physically connected to the network.
n Ping the IP Address of LAN1.
n Check that the LAN1 IP Address, Mask, and Gateway are valid using the STATUS but-
ton to display LAN1 STATUS.
n LAN1 may be disabled. If needed, turn it on using the Keypad/Display as follows:
1. Press MENU.
2. Select 1) LAN1.

n The Web Server may be turned off.
n Cycle the power off and on again. Depending on the configuration of the
SERVICES - Startup page, the web server may be available when the Syn-
cServer finishes rebooting. See Halting the SyncServer (on page 15).
n Otherwise, log into the command line interface and turn the web server on using
the HTTP on command. See Command Line Interface (on page 107).
n After logging in to the web interface, select Auto for Web Server on the
SERVICES - Startup page.

Using NTP
AddingServerAssociations
NTP server and peer associations provide an important backup source of time if the Syn-
cServer's Input References are unavailable. Having two or more server or peer associations
is important for reliability and redundancy.
(Optional) The user can add associations for NTP servers that reside on the company net-
work:
n For NTP servers that the user cannot configure, add server associations, as described
below.
n For NTP servers that the user can configure, add peer associations as described in
Adding Peer Associations (on page 155).
Note: Avoid creating server associations on two NTP servers that point to each other. Use
peer associations instead.
(Optional) If the SyncServer is located outside the United States, the user can also add at
least one server association that points to a local NTP server. This provides a shorter net-
work path, which improves timing precision and accuracy. Often, public NTP servers are
operated by national timekeeping authorities, telecommunications companies, and uni-
versities. To find a local NTP server, search the Internet for "Public NTP servers". Include
