Installation Manual
H3C SecPath F1000-E Firewall
Chapter 1 Product Overview
1-23
Note:
For the installation of the port lightning arrester, refer to section 4.6 “Installing a Port
Lightning Arrester (Optional)” in Chapter 4 “Installing the Firewall”.
1.4.10 Power Lightning Arrester (Optional)
Before connecting an outdoor AC power supply to the firewall, you need to install a
lightning protection busbar at the AC power input end and then connect the AC power
cord to a lightning protection busbar to protect the firewall against lightning strokes. In a
heavy lightning area, you are recommended to install a power lightning arrester.
The following power lightning arrester can be installed on the F1000-E. The
specifications for the power lightning arrester are as follows:
Maximum discharge current: 6500 A, protection voltage: 500 VAC to 220 VAC.
Note:
For the installation of the power lightning arrester, refer to section 4.7 “Installing a
Power Lightning Arrester (Optional)” in Chapter 4 “Installing the Firewall”.
1.4.11 Signal Lightning Arrester (Optional)
Generally, you need to connect a signal lightning arrester (namely, a transient
over-voltage protection) before connecting a signal cable to the firewall. This can
protect electronic devices against surge over-voltage resulting from lightning strokes
and other interferences, and minimize impact on the firewall.
The F1000-E supports three types of signal lightning arresters:
z
Voltage-limiting protection–signal lightning arrester–maximum discharge current
2.5 KA/protection voltage 25 V–SMB–75J/SMB–75J–1 W–10 Mbps.
z
Voltage-limiting protection–signal lightning arrester–maximum discharge current
2.5 KA/protection voltage 25V–BNC–75K/BNC–75K–10 Mbps.
z
Voltage-limiting protection–signal lightning arrester (U port)–maximum discharge
current 3 KA/common mode 400 V/differential mode 170V–RJ-11
