4500E 9000W Power Supply
The Cisco Catalyst 4500E platform is the most widely deployed modular access platform and has been the
industry leader for Power over Ethernet (PoE) technologies. The 9000W power supply offers several benefits:
●
PoE scale: Unprecedented scale for PoE (802.3af), Power over Ethernet Plus (PoEP) (802.3at), and
Universal PoE (UPoE) devices in Cisco Catalyst 4500E Series Switches
●
Energy efficiency: 80PLUS Platinum (formal certification pending) performance with more than 90-percent
efficiency
●
Lower total cost of ownership (TCO):
◦
Lower capital expenditures (CapEx): Upgrade only the power supply in existing E-Series chassis to avail
the benefits
◦
Lower operating expenses (OpEx): Intelligent power monitoring and troubleshooting capabilities

PoE Scale
The new 9000W power supply now makes the Cisco Catalyst 4500E platform the most scalable modular platform
in the industry in terms of its inline power delivery capabilities. The 9000W power supply can support up to 384
ports of PoE, 232 ports of PoEP, and 116 ports of UPoE simultaneously in a fully redundant (1 + 1) configuration
(Table 1).
