Can be installed in any non-supervisor module slot.
Ensure that the chassis power supply configuration supports the PoE budget adequately. Use
the Cisco Power Calculator for power budgeting estimates and to determine power supply
requirements for a specific PoE configuration.
Some legacy Cisco powered devices (like 7910, 7940, 7960 IP phones and AP350 wireless
access points) are incompatible with Type 4 Power Supply Equipments (PSEs), as defined
in the IEEE 802.3bt standard. If connected, the PSE reports a ‘Tstart’ or ‘Imax’ fault with
each periodic attempt at providing power to the powered device. For continued use of these
legacy Cisco powered devices, connect them to Cisco PoE+/UPOE PSEs.
C9400-LC-48H module is supported only on Cisco IOS XE Release 16.12.1 and later releases.
Before inserting the module, ensure that the device software is Cisco IOS XE Release 16.12.1
or a later release.
Before downgrading the software on the device from Cisco IOS XE 16.12.1 to earlier releases,
ensure that you remove the C9400-LC-48H module.
