Port protective unit–single port, maximum discharge current (8/20 μs waveform): 5 kA; output voltage
(10/700 μs waveform): core-core < 40 V, core-ground < 600 V.
NOTE:
For how to install the port lightning arrester, see the chapter “Installing the router.”
Power lightning arrester (optional)
Before connecting an outdoor AC power supply to the router, you must install a lightning protection
busbar at the AC power input end and then connect the AC power cord to the lightning protection
busbar to protect the router against lightning strikes. In a heavy lightning area, H3C recommends
installing a power lightning arrester.
The following power lightning arrester can be installed on the SR6602. The specifications for the power
lightning arrester are as follows:
Maximum discharge current: 6500 A; protection voltage: 220 VAC to 500 VAC.
NOTE:
For how to install the power lightning arrester, see the chapter “Installing the router.”
Signal lightning arrester (optional)
Typically, you must connect a signal lightning arrester—a transient over-voltage protection—before
connecting a signal cable to the router. This can protect electronic devices against surge over-voltage
resulting from lightning strikes and other interferences, and minimize impact on the router.
The SR6602 supports the following types of signal lightning arresters:
• Voltage-limiting protection-signal lightning arrester-maximum discharge current 2.5KA/protection
voltage 25V--SMB-75J/SMB-75J-1W-10Mbps
• Voltage-limiting protection-signal lightning arrester-maximum discharge current 2.5KA/protection
voltage 25V-BNC-75K/BNC-75K-10Mbps
• Voltage-limiting protection-signal lightning arrester (U port)-maximum discharge current
3KA/common mode 400 V/differential mode 170V-RJ11.
