NOTE: Each power supply must be connected to a dedicated power source
outlet.
NOTE: If you have a Juniper Care service contract, register any addition,
change, or upgrade of hardware components at
https://www.juniper.net/customers/support/tools/updateinstallbase/. Failure
to do so can result in significant delays if you need replacement parts. This
note does not apply if you replace existing components with the same type
of component.

Removing a 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 device functions.
NOTE: After you remove a transceiver or when you change the media-type
configuration, wait for 6 seconds for the interface to display the operational
commands.
