other network information are displayed on the unit front panel when the unit boots up.
If you plan on allowing your NetClock to use this negotiated DHCP Address on a permanent
basis, you can skip the following topics about setting up an IP address, and instead proceed to
"Accessing the WebUI" on page53, in order to complete the NetClock configuration process.
Please note:
Unless you are using DNS in conjunction with DHCP (with the client configured using NetC
lock's hostname instead of IP address), Spectracom recommends to disable DHCP for NetC
lock, and instead use a static IP address. Failure to do this can result in a loss of time
synchronization, should the DHCP server assign a new IPaddress to NetClock.
2.11.2 Assigning a Static IP Address
Spectracom recommends assigning a static IP address to NetClock, even if the unit is connected
to a DHCP server.
This can be accomplished in several ways:
a.
Via the keypad and information display on the front panel of the unit, see "Setting Up
an IP Address via the Front Panel" on page47. (NetClock 9483 only; If you are setting
up a NetClock 9489 unit – which does not have a front panel information display and
keypad – see "Setting Up a Temporary IP Address Remotely" on page51.)
b.
By connecting the NetClock to an existing DHCP network, temporarily using the
assigned DHCP address, see "Setting Up a Static IP Address via a DHCP Network" on
page49.
c.
By connecting a Personal Computer to NetClock via a serial cable, see "Setting Up an
IP Address via the Serial Port" on page50.
d.
By connecting a Personal Computer directly to NetClock via a dedicated Ethernet cable,
see "Setting up a Static IP Address via Ethernet Cable" on page51.
Note: For information on configuring routing tables, see "Static Routes" on
page64.
2.11.2.1 Assigning a New Static IP Address
To configure a NetClock unit that has not yet been assigned a custom IP address (e.g., because
your network does not support DHCP), there are two ways to enter the desired static IP
address, subnet mask, and gateway address:
The front panel keypad and its 4-line information display (NetClock 9483 only), or
a personal computer, connected to the NetClock unit via a serial cable, or via a ded
icated Ethernet cable.
