Connect fiber cables
Step4
After power-on, check the SFP LED. For the status of the SFP LED, refer to the table describing the
behaviors of the LEDs on NSQ1GT8C40 in Chapter 1 “Firewall Overview.”
Upon the connection of an XFP transceiver, you need to check the XFP LED. For details, refer to the
table describing the behaviors of the LEDs on NSQ1XP20 in Chapter 1 “Firewall Overview.”
Note that:
z
Avoid excessively bending the optical fiber cables, with the curvature radium less than 10 cm (3.9
in.).
z
Ensure that the Tx and Rx of the SFP/XFP transceiver module are connected correctly.
z
Keep the end-faces of optical fiber cables clean.
z
Do not look directly into an open optical Ethernet interface, because invisible rays emitted from the
optical Ethernet interface may hurt your eyes.
z
Cover the dust cover if no optical transceiver is connected to the optical Ethernet interface.
Verifying Installation
Each time you power on the firewall during installation, you verify that:
z
There is enough space around the firewall for heat-dissipation and the workbench is stable
enough.
z
The power supply matches the requirements of the firewall.
z
The PGND cable of the firewall is correctly connected.
