Catalyst 4500 Power Consumption and Heat Dissipation
I am currently working on a project to set up a new LAN and WAN for my customer's new site. This site will be multi-level building, with Cisco IP Phones for each floor. I have sized up each floor to require 1 floor switch with the following spec:
- Cat 4506 with a single SupII+
- 2x PWR-C45-4200ACV, in redundant mode
- 3-5x WS-X4548-GB-RJ45V
During one of our discussions with the building and electrical contractors, there are several questions around the power consumption, heat dissipation, and power oversubscription that I could not find anywhere on the CCO. The questions are as follows:
1. What is the typical power drain of the redundant PSU?
2. What is the heat dissipation of the redundant PSU?
3. Considering the max power output of the 4200W ACV PSU, the electrical contractor believes that the heat dissipation should've been higher than the 3580 BTU/hr that the data sheet claims. Is 3580 BTU/hr max heat dissipation for each 4200W PSU accurate?
4. In the event that all ports on the switch are configured as "static ports", in the event of a power oversubscription, what is the order of ports being shutdown by the switch? Is it starting from the vert last port on the last (i.e. bottom) blade?
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
j ai une question j ai achete un routeur cisco 887VA-k9 , je le configuré avec la configuration ci- dessous
si je le lier avec mon pc portable sur l un de ses ports directement ça marche toute est bien ( la connexion internet + m...
