Signal Lightning Arrester (Optional); System Software - 3Com H3C SECPATH F5000-A5 ADVANCED VPN FIREWALL 12-PORT GIGABIT ETHERNET MODULE Installation Manual

The following power lightning arrester can be installed on the F5000-A5. The specifications for the
power lightning arrester are as follows: Maximum discharge current: 6500 A, protection voltage: 220
VAC to 500 VAC.
For the installation of a power lightning arrester, refer to Chapter 4 "Installing the Firewall."

Signal Lightning Arrester (Optional)

Generally, you need to install a signal lightning arrester between a signal cable and the connected
device. This can protect electronic devices against surge over-voltage resulting from lightning strokes
and other interferences, and minimize impact on the device.
The device supports three types of signal lightning arresters:
Voltage-limiting
2.5KA/protection voltage 25V—SMB-75J/SMB-75J-1W-10Mbps.
Voltage-limiting
2.5KA/protection voltage 25V-BNC-75K/BNC-75K-10Mbps.
Voltage-limiting protection parts–single lightning arrester (U port)-maximum discharge current
3KA/comman mode 400 V/differential mode 170V-RJ11.
For the installation of a signal lightning arrester, refer to Chapter 4 "Installing the Firewall."

System Software

The F5000-A5 uses the Comware V5 software platform, H3C's core software platform.
Based on the IPv4/IPv6 dual stack, the Comware V5 software platform integrates link-layer protocols,
routing protocols, Multi-Protocol Label Switching (MPLS), virtual private network (VPN), security, and
other data communications features. It is scalable and portable because it adopts a componentized
architecture and effectively encapsulates and masks different operating systems and hardware.
