Installing a port lightning arrestor (optional)
NOTE:
•
Only 10/100 Mbps RJ-45 copper Ethernet ports need to be equipped with port lightning arresters.
• No port lightning arrester is shipped with the router unless ordered.
Before connecting an outdoor Ethernet cable to an Ethernet port, install a port lightning arrester to protect
the router against lightning strokes.
The following port lightning arrester can be installed on the SR6602. The specifications for the port
lightning arrester are as follows: Port protective unit–single port, maximum discharge current (8/20μs
waveform): 5 kA, output voltage (10/700μs waveform): core-core < 40 V, core-ground < 600 V.
Installation procedures
Follow these steps to install a port lightning arrestor:
Step1 Use a double-faced adhesive tape to stick the port lightning arrester to the router. 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 router.
Step3 Use a multimeter to check the connection between the grounding cable of the port lightning arrester and
the grounding screw of the router.
Step4 Follow the instructions to connect the port lightning arrester with a transit cable. The external cable
should be connected to the IN end and the transit cable to the OUT end. Check whether the LED on the
interface module is normal.
NOTE:
Read the instructions carefully before installing the port lightning arrester.
Step5 Bundle the cables with a cable tie.
