Exceptional Reliability
The Cisco Catalyst 4900 Series offers redundant
hot-swappable internal AC or DC power supplies
for nonstop operation. The 1+1 power supply
design provides A-to-B failover when power
supplies are connected to different circuits. AC
and DC power supplies can be mixed in the same
unit for maximum deployment flexibility. The Cisco
Catalyst 4900 Series also features a hot-swappable
fan tray with four redundant fans for additional
serviceability and availability.
