No power lightning arrester is provided with the device. Purchase one if required.
If the AC power cord for an AC power module is routed from outdoors, use a power lightning arrester
for the device to protect against damages caused by lightning strikes. First connect the AC power
line routed from outdoors to the arrester and then connect the power cord from the device to the
arrester.
You can use a screw and releasable cable tie to attach the power lightning arrester to the rack,
workbench, or wall in the equipment room.
Connecting Ethernet cables
Connecting a copper Ethernet port
The copper Ethernet ports on the device and its interface module are MID/MDIX autosensing. You
can use either a straight-through or a cross-over network cable to connect a copper Ethernet port.
For more information about Ethernet twisted pair cables, see "Ethernet twisted pair cable."
To connect a copper Ethernet port:
1.
Connect one end of the Ethernet cable to the copper Ethernet port of the device, and the other
end to the Ethernet port of the peer device.
2.
Examine whether the LEDs of the Ethernet port are normal. For more information about LEDs,
see "LEDs."
NOTE:
After connecting the device to the network, you can use the
ping
or
tracert
command to verify
network connectivity. For more information about the commands, see the command reference for
the device.
Connecting a fiber port
WARNING!
Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare into
beams or view directly with optical instruments when the device is operating.
