Installing a Port Lightning Arrester (Optional)
z
You need to install lightning arresters only for 10/100 Mbps RJ-45 Ethernet ports.
z
The U200 series devices are not shipped with lightning arresters for ports in case of standard
configuration. You can purchase one if needed.
Before connecting an outdoor Ethernet cable to an Ethernet port, install a port lightning arrester to
protect the device against lightning strikes.
The specifications of the port lightning arrester available for the U200 series are as follows:
z
Single port
z
Maximum discharge current (8/20
μ
s waveform): 5 kA
z
Output voltage (10/700
μ
s waveform): core-core < 40 V, core-ground < 600 V
Tools Required
z
Phillips or flat-blade screwdriver
z
Multimeter
z
Diagonal pliers
Installation Procedure
Follow these steps to install a port lightning arrester:
Step1
Use a double-faced adhesive tape to stick the port lightning arrester to the device. The port lightning
arrester should be as close to the grounding screw as possible.
Step2
Cut short the grounding cable of the port lightning arrester according to its distance to the grounding
screw. Then, fix the grounding cable onto the grounding screw of the device.
Step3
Use the multimeter to check the connection between the grounding cable of the port lightning arrester
and the grounding screw of the device.
Step4
Follow the instructions accompanying the lightning arrester to connect the lightning arrester with a
conversion cable. When doing that, connect the external cable to the IN end while the network
conversion cable to the OUT end. Check that the status of the LEDs on the connected interface module
is normal.
Read the instructions carefully before installing a port lightning arrester.
Step5
Bundle the cables with cable ties neatly.
