Replacing SFP and XFP Transceivers on I/O Cards on the SRX3400
Small Form-factor Pluggable (SFPs) and 10-Gigabit Small
Form-factor Pluggable (XFPs) are optical transceivers that are installed
in IOCs. SFPs and XFPs are hot-insertable and hot-removable.
Removing an SFP or XFP does not interrupt IOC functioning,
but the removed SFP or XFP no longer receives or transmits data.
Juniper strongly recommends the use of Juniper transceivers.
Juniper cannot guarantee correct operation if non-Juniper transceivers
are used. The transceiver type can be different in each port, as long
as a supported part number is used.
To replace an SFP or XFP transceiver:
- Have ready a replacement transceiver or a transceiver
slot plug, an antistatic mat, and a rubber safety cap for the transceiver.
- Attach an electrostatic discharge (ESD) grounding
strap to your bare wrist and connect the strap to one of the ESD points
on the chassis.
- Label the cables
connected to the transceiver so that you can reconnect them correctly
Do not look directly into a fiber-optic
transceiver or into the end of a fiber-optic cable. Fiber-optic transceivers
contain laser light sources that can damage your eyes.
- Remove the cable connector plugged into the transceiver.
- Carefully drape the disconnected cables to prevent
the cable from developing stress points.
Avoid bending fiber-optic cable beyond its minimum
bend radius. An arc smaller than a few inches in diameter can damage
the cable and cause problems that are difficult to diagnose.
- Pull the ejector handle out from the transceiver
to unlock the transceiver.
Make sure that you open the ejector handle completely
until you hear it click. This prevents damage to the transceiver.
Use needlenose pliers to pull the ejector handle out from the
- Grasp the transceiver ejector handle and pull the
transceiver approximately 0.5 in. (1.3 cm) out of the IOC.
- Using your fingers, grasp the body of the transceiver
and pull it the rest of the way out of the IOC.
Figure 58: Removing SFPs or XFPs
- Place a rubber safety cap over the transceiver.
- Place the removed
transceiver on an antistatic mat or in an electrostatic bag.
- Repeat steps 3 through 10 for each transceiver
you need to replace.
- Take each new transceiver to be installed out of
its electrostatic bag and identify the port on the IOC where
it will be installed.
- Verify that each transceiver is covered by a rubber
safety cap. If it is not, cover the transceiver with a safety cap.
- Carefully align the transceiver with the slots
in the IOC . The connectors should face the IOC.
- Slide the transceiver until the connector is seated
in the IOC slot. If you are unable to fully insert the transceiver,
make sure the connector is facing the right way.
- Close the ejector handle of the transceiver.
- Remove the rubber safety cap from the transceiver
and the end of the cable. Reconnect the cables into the transceivers.
- Verify that the status LEDs on the IOC faceplate
indicate that the SFP or XFP is functioning correctly. You can also
verify that the IOC is functioning by issuing the show chassis fpc
