Cisco this has improved their Catalyst switch line with a gear that boosts Power-over-Ethernet support, backup power and failover issues and 10G Ethernet connectivity at the LAN edge. According to the news on Cisco Catalyst 3750-E and 3560-E switches from Cisco target dense PoE deployments, where a majority of ports on a switch require in-line power for attached devices, such as IP phones or wireless LAN access points.
These Cisco switches have twice the PoE support as previous models and include expanded 10G Ethernet uplink options. Also Cisco has increased the power supplies on its Catalyst 6500 series chassis to power as many as 420 ports in a chassis with PoE.
The Catalyst 3750-E comes in 24- and 48-port versions. Each has 10/100/1000Mbps autosensing ports and modular port slots, which can accept dual-port Gigabit Ethernet or single-port 10G Ethernet uplinks.
The switch stacks with as many as eight other 3750-E switches or older versions of the Catalyst 3750, with Ciscoâ€™s StackWise interconnection technology. This lets switches be linked by a common 64Gbps interconnected backplane while being managed and configured as a single logical network device.
