Chapter 2: Connecting to the ER-1000
TR0190 Rev. A1 14
used for initial configuration and for accessing devices whose configuration settings are
unknown.
2.2 Connecting to an Unconfigured EL-500
Use the Static Configuration interface with IP address 169.254.253.253 and netmask
255.255.0.0 to establish network connectivity to an unconfigured EL-500.
The Static Configuration interface functions only with the EL-500’s wired
interface. Do not try to access the EL-500 over a wireless link using the
address of this interface.
To connect to an EL-500 using its Static Configuration IP address, you must configure your
computer’s IP address to be in the 169.254.253.253/16 subnet, e.g. 169.254.253.1 and
connect the computer’s Ethernet cable to the “PC” port on the EL-500’s PoE injector.
ENSURE THAT THE DATA CONNECTION FROM THE PC OR THE LAN IS MADE
TO THE “PC” PORT. DO NOT CONNECT ANY DEVICE OTHER THAN THE EL-
500 TO THE PORT LABELED “CPE” ON THE PoE INJECTOR. NETWORK
EQUIPMENT THAT DOES NOT SUPPORT PoE CAN BE PERMANENTLY
DAMAGED BY CONNECTING TO A PoE SOURCE. NOTE THAT MOST
ETHERNET INTERFACES ON PERSONAL COMPUTERS (PCs),
LAPTOP/NOTEBOOK COMPUTERS, AND OTHER NETWORK EQUIPMENT
(E.G. ETHERNET SWITCHES AND ROUTERS) DO NOT SUPPORT PoE.
Since the Static Configuration IP address is the same for all EL-500s, you
should not simultaneously connect multiple EL-500s to a common LAN and
attempt to access them using the Static Configuration IP address.
