I was going to buy a PoE daughterboard (PPWR-DCARD-16ESW?) and fit it to the NM-16ESW switch but I'd like to make sure I'm not wasting my money. I want PoE to for some ip phones I'll be connecting to the switch. I think I read somewhere the 2600 routers won't power the phones, is this true?
Unfortunately in order to be able to utilise the capabilities of the PoE daughterboard you will also need to provision an external power supply.
The PPWR-PS-CHASSIS is specifically for the 2600 and 3600 series. It is an external power unit which can support 4 360W power supplies. Or there is the PWR-CHASSIS-360W, which is the chassis and a single 48V 360W power supply.
â¢ PPWR-PS-CHASSIS: The power chassis is an external chassis that can support up to four 360W power supplies, which can provide power over ethernet to Cisco phones or wireless access points. This chassis can support up to 144 IP phones @ 10W per port (or less devices at <10W per port). The external PPWR-PS-CHASSIS is for use with the Cisco 2600 and 3600 Series. The 2800, 3700, and 3800 Series internal power supply can be upgraded to provide Power over Ethernet and the external chassis is not used for these routers. Also available is a custom cable that connects the power supply to the Cisco EtherSwitch Modules. Cable options allowing for power supply redundancy are also available. The power over ethernet works over standard Category 5 unshielded twisted-pair (UTP) cable up to 100 meters and allows direct power instead of using wall power with a transformer. This allows customers to use existing Category 5 UTP installations. The Cisco EtherSwitch Module power over ethernet implementation passes the required U.S. and international safety regulations and compliance measures.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
