Connecting
You can connect SFP modules to these ports while the router is operating normally. The SFP ports are
labeled
ETH 1/2
and
ETH 2/2
.
When installing or removing SFP modules, observe these guidelines:
•
Removing and installing an SFP module can shorten its useful life. Do not remove and insert any
module more often than is absolutely necessary.
•
To prevent ESD damage, follow your normal board and component handling procedures when
connecting cables to the switch and other devices.
This section describes how to install SFP modules. SFP modules are inserted into the SFP ports shown
in
Figure 3-21
.
Step 1
Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2
For fiber-optic SFP modules, remove the dust plugs and store them in a clean location for reuse.
Step 3
Position the SFP transceiver module in front of the socket opening, and insert the SFP into the socket
until you feel the connector latch into place.
Step 4
Remove the dust plugs from the network interface cable LC connectors.
Step 5
Inspect and clean the LC connector's fiber-optic end-faces.
Step 6
Thread the SFP cable through the chassis cable ports that are reserved for the SFP cables (
Figure 6-7
).
Note
You must use cable glands with the chassis cable ports on the router. See the
“External Connections and
Chassis Cable Ports” section on page 6-12
.
Step 7
Attach the network interface cable connector to the SFP transceiver module.
