•
An ESD wrist strap with a plug for connection to the ESD connector on the router chassis.
DANGER
For safety reasons, the ESD wrist strap should contain a 1 megohm series resistor.
Follow these steps to replace a fiber-optic transceiver in a 10 Gbps Ethernet port.
1.
Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector
located on the front of the router.
2.
Disconnect the two fiber cable connectors from the port connectors.
3.
Replace the protective cover on the port connectors.
4.
Pull down the latch on the front of the transceiver.
5.
Pull the transceiver out of the port and place it in an anti-static bag for storage.
6.
Remove the new transceiver from the protective packaging.
7.
Insert the fiber-optic transceiver into the port until it clicks into place. Fiber-optic transceivers
are keyed to prevent incorrect insertion.
Cabling a fiber-optic transceiver
To cable a fiber-optic transceiver, perform the following steps.
Fiber-optic cabling steps
1.
Before cabling a fiber-optic transceiver, it is strongly recommended that you clean the cable
