own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in the
cable management system. Placing fasteners on the loop helps to maintain its shape.
CAUTION: Do not let fiber-optic cable hang free from the connector. Do not allow
fastened loops of cable to dangle, which stresses the cable at the fastening point.
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.

Install a QSFP28 Transceiver
The transceivers for Juniper Networks devices are hot-removable and hot-insertable field-replaceable
units (FRUs): You can remove and replace them without powering off the device or disrupting the device
functions.
NOTE: After you insert a transceiver or after you change the media-type configuration, wait for
6 seconds for the interface to display operational commands.
NOTE: We recommend that you use only optical transceivers and optical connectors purchased
from Juniper Networks with your Juniper Networks device.
