1.4.8 RPS (Optional)
The redundancy power supply (RPS) can provide power supply to maintain the normal
system operation for a short period when the system power supply fails.
The RPS uses a control pin to control its output status. When the system power supply
fails, it sends a LOW signal to the control pin of the RPS. Upon receiving the LOW
signal, the RPS switches to the output status within 10 ms and starts to supply power to
the firewall.
The F1000-E provides two power inputs: AC power input and RPS input. They can
guarantee the firewall to continue working when one power supply fails, thus providing
high reliability.
Note:
z
The RPS is an optional component not shipped with the firewall.

For the RPS installation, refer to section 4.9.3 “Connecting the RPS DC Power
Cable” in Chapter 4 “Installing the Firewall”.
1.4.9 Port Lightning Arrester (Optional)
Before connecting an outdoor Ethernet cable to an Ethernet port, you can install a port
lightning arrester to protect the firewall against lightning strokes.
The following port lightning arrester can be installed on the F1000-E. The specifications
for the port lightning arrester are as follows:
Port protective unit–single port, maximum discharge current (8/20
μ
s waveform): 5 kA,
output voltage (10/700
μ
s waveform): core-core < 40 V, core-ground < 600 V.
