a. A steady green light beside the Console Port means the system has powered up
correctly.
b. A steady green light beside the uplink port indicates a 10Mbit or 100Mbit per
second connection respectively. If both lights are unlit, the Uplink to your 
network failed. 
3. Make the device connections. Each EthIR Switch is equipped with two rows of RJ
45 jacks. The top jack of each port is the Ethernet “pass through” port. The 
bottom jack of each port is the infrared connection port. 
a. If your intention is to connect only infrared devices to the EthIR Switch, see 
“Infrared Mode” below.
b. If you are connecting a combination of infrared and Ethernet devices to the
EthIR Switch, see Pass Through Mode (ES208 / 216 only) on the next page.
Install EthIR Switch (ES101 / 301 / 3011b / 1000)
To install the single port EthIR Switch: 
 
1. Plug in one end of an Ethernet UTP cable into the uplink port and the other end 
into a network patch panel or Ethernet wall jack leading to a patch panel.
2. Connect the EthIR Beam to one end of a mini-dim cable and plug the other end
into the mini-dim plug on the switch.
3. Power up the system by plugging it into an AC outlet. Once powered the EthIR
Switch indicator lights display its status illustrated as follows: 
a. Uplink - (indicates state of network connection) 
b. Status - (indicates progress of obtaining an IP address from DHCP server) 
c. Power  - ES101 (indicates state of power) 
d. PC - ES301 (indicates Ethernet port in use) 
 
The LED indicator light on the EthIR Beam (EB100) indicates data transmission via 
infrared.
