Subnet mask (for the network)
Gateway address

2.12.1 Dynamic vs. Static IP Address

On a DHCP network (Dynamic Host Configuration Protocol), SecureSync's IP address will be
assigned automatically once it is connected to the DHCP server. This negotiated address and
other network information are displayed on the unit front panel when the unit boots up.
If you plan on allowing your SecureSync 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 Web UI" on page 52, in order to complete the SecureSync configuration pro
cess.
Please note:
Unless you are using DNS in conjunction with DHCP (with the client configured using
SecureSync's hostname instead of IP address), Spectracom recommends to disable DHCP for
SecureSync, 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 IP address to SecureSync.

This is the unique address assigned to the SecureSync unit by the network admin
istrator. Make sure the chosen address is outside of the DHCP range of your
DHCP server.
Note: The default static IP address of the SecureSync unit is
10.10.201.x
The subnet mask defines the number of bits taken from the IP address that are used
in the network portion. The number of network bits used in the net mask can range
from 8 to 30 bits.
The gateway (default router) address is needed if communication to the
SecureSync is made outside of the local network. By default, the gateway is dis
abled.
Make sure you are assigning a static IP address to your SecureSync unit
Note:
that is outside of the DHCP range defined for the DHCP server. Your system
administrator will be able to tell you what this range is.
(x= dependent on ETH port).
