This appendix provides the specifications for the AC-input and DC-input power supplies supported on the Catalyst 4948E switch.
Tip For additional information about the Cisco Catalyst 4948E and the Catalyst 4948E-F switches (including configuration examples and troubleshooting information), see the documents listed on this page:
