4503 supervisor engine query

[mirehteshamali]

Hi all,

1)on 4503 we have 3 slots , can i used 3 48 10/100 line cards in these three available slots or do i need to reserve on slot for supervisor .

where does supervisor fits in .? in these line slots or their is a seprate place for it ?

2) we are deploying 150 access points , can i look for multiple 3560 48 port  POE switches to power them .

  i mean can i use 4  48 port 3560 switches , almost all port consumed for inline power, ?

Thanks

Hi there!

1. All 4500's require a SUPervisor. Essentially SUP's are the brains and the muscle of the 4500 range. That is, it provides the switching logic and the connections between all the ports.

In the 4503, SLOT1 is reserved for the SUP.

A good start is:

2. The number of ports that can be utilised for PoE on a 3560 depends on the model and power requirements of the device your connecting.

Q. How many devices can the Cisco Catalyst 3560 Series power?

A. The Cisco Catalyst 3560 Series 24-port PoE configurations can support 24 simultaneous full-powered PoE ports at 15.4W for maximum powered device support. Using Cisco Catalyst Intelligent Power Management, the 48-port version can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between. The Cisco Catalyst 3560 Compact Switch can support 8 simultaneous full-powered PoE ports at 15.4W.
