I'm really interested in getting an idea of how to use EEM Tcl scripts or other method to get PoE for our phones switched off at night to save power. Does anyone know if there's any whitepapers on doing this? I saw the idea on a Cisco slide already and have searched real hard to find a solution but to no avail. All I'm after is PoE being switched off on a port range between 19:00 and 06:00 simple as that!
I'm curious why Cisco pimped the idea as a way of being more power efficient if the power supply is pulling constant power regardless of PoE usage. I hope this isn't a case of 'jumping on the green bandwagon' from Cisco. It'd be dissapointing if it is.
I've got a spare 3560PoE switch kicking around so I can power that up - monitor it, then run round to our production switches which are fully PoE enabled and used, then compare the two power consumption results. In the meantime - if anyone does now how to do this using EEM then please post as I'd like to provide the option should my test prove useful. I'll also post my power consumption results for everyones benefit.
Yup! And the script does not run for some reason to turn on the phones in the morning. Business is down. How much does that cost per minute of downtime vs how much you are actually saving on your power bill vs "green marketing" material for your enterprise?
Those are my three. Turning off POE would be great. But safety. Having the screens go blank like a screen saver, much better. They would draw less power from the switch. (assuming)
