Cisco Catalyst 9400 Series 48-Port 5G multigigabit (RJ-45) UPOE+ Line Card (C9400-LC-48HN)

The Catalyst 9400 Series switch 48 port multigigabit UPOE+ line card supports 5/2.5 G multigigabit, 1000M/100M, Cisco UPOE^®+, Cisco UPOE, PoE+ and PoE. Designed for higher bandwidth PoE powered Wi-Fi 6/6E deployment, IEEE 802.3bt compliant 48-port mGig 90W UPOE+ line card provides line-rate data and power over a single cable to power other devices like digital signage, security cameras, thermal cameras with PTZ features, LED lighting fixtures and large display screens. Cisco UPOE+ offers reduced cabling and installation costs without need for permits, device daisy-chaining applications that require higher power draw, uninterrupted power and data using dual supervisors, real-time device information and centralized management and remote control, faster and flexible device installation, where devices can be positioned in practical location instead of proximity to electrical outlets. Additionally, these line cards provide advanced energy management through standards-based Energy Efficient Ethernet and lowest thermal dissipation per watt of energy sourced.
