Connect the U2049XA sensor
Connect the U2049XA via any of the following LAN operating modes:
– Dynamic IP (Dynamic Host Configuration Protocol or DHCP)
– Auto IP (Local PC control or isolated (non-site) LAN)
– Static IP (Manual mode)
The default LAN operating mode of the U2049XA is Dynamic IP.
Dynamic IP and Auto IP are enabled on the U2049XA shipped from Keysight. This allows
the U2049XA to automatically obtain an address on the network.
The U2049XA communicates with the DHCP server to obtain the LAN interface
configuration. If the DHCP server is not detected, then either the DHCP server is not
present or it does not allow the U2049XA to obtain an IP address. The U2049XA will then
try to obtain the LAN configuration using AutoIP if enabled, otherwise the U2049XA will try
to use the static IP set in the U2049XA. If required, push the LAN reset switch to reset the
U2049XA LAN configuration to a known default state.
Dynamic IP mode
In this mode, the IP address, subnet mask, and default gateway values are obtained from a
DHCP server.

Connect the U2049XA via Dynamic IP
NOTE
The LED indicator will turn red indicating the following error when the DHCP server is not
detected:
-310, "System error;The sensor could not obtain a LAN configuration using DHCP. The
sensor will try to obtain IP address using AutoIP if enabled”.
