Page 204 T320 Core Router Hardware Guide CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light. CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius.
Page 205: Installing A T320 Fpc
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis. For more information about ESD, see “Preventing Electrostatic Discharge Damage to a T320 Router” on page 210. Place the FPC on an antistatic mat.
Page 206 T320 Core Router Hardware Guide CAUTION: When the FPC is out of the chassis, do not hold it by the ejector handles or edge connectors. They cannot support its weight. Slide the FPC all the way into the card cage until you feel resistance.
Page 207: Figure 95: Installing A T320 Fpc
You can also verify correct FPC and PIC functioning by issuing the show chassis fpc commands described in “Maintaining T320 FPCs” on page 116 show chassis fpc pic-status and “Maintaining T320 PICs and PIC Cables” on page 121. Figure 95: Installing a T320 FPC Copyright © 2010, Juniper Networks, Inc.

T320 Core Router Hardware Guide Removing a T320 SFP Small form-factor pluggables (SFPs) are transceivers that can be removed from a PIC. SFPs are hot-insertable and hot-removable. Removing an SFP does not interrupt PIC functioning, but the removed SFP no longer receives or transmits data.
Page 217: Installing A T320 Sfp
Chapter 14: Replacing the T320 Router Hardware Components CAUTION: 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 away from the SFP faceplate to unseat the SFP from the PIC.
Page 218: Replacing A T320 Xenpak Module
Verify that the status LEDs on the PIC faceplate indicate that the SFP is functioning correctly (there is an LED for each SFP port). For more information about the PIC LEDs, see the T320 Core Router PIC Guide. You can also verify PIC functioning by issuing command.
