3.2 CONNECTING THE ETHERNET INTERFACE
This section describes how to connect the Ethernet ports to your network equipment.
The RJ-45 ports labeled Ethernet are the Auto-MDIX10/100Base-T interface. These
p
orts are designed to connect directly to a 10/100Base-T device or network. You may
connect these ports to a hub or PC using a straight through or crossover cable that is
up to 328 ft long.
3.3 CONNECTING POWER
3.3.1 External AC universal power supply
1. Connect the power cord from the AC socket to the IEC-320 power entry connector
o
n the universal input power supply.
2. Connect the barrel plug to the Power c
onnector on the LB512A-KIT.
NOTE: The LB512A-KIT p
owers up as soon as it is plugged into an AC outlet—there is
no power switch.
3.3.2 DC Power
The 36-60 VDC DC to DC adapter is supplied with the DC version of the LB512A-KIT.
Th
e black and red leads plug into a DC source (nominal 48VDC) and the barrel power
connector plugs into the barrel power supply jack on the LB512A-KIT. (See Figure 5.)
The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to volt-
age, current, anticipated temperature, flammability, and mechani-
cal serviceability.
The external AC adaptor shall be a listed limited power source that
incorporates a disconnect device and shall be positioned within
easy reach of the operator. Ensure that the AC power cable meets
all applicable standards for the country in which it is to be
installed, and that it is connected to a wall outlet which has earth
ground.
