As a followup to the previous post on power calculation and estimation, I should add a couple of points — one on published Cisco reference material, the other on a handy command to run on your devices themselves once they’re already live in your datacenter/garage/office .

Cisco has a nice tool on their customer pages they call the Cisco Power Calculator. The calculator will let you specify a (supported) chassis, loaded modules, cards, attached PoE devices, input voltage (e.g., 110 or 220 Volts), and come up with estimated figures for power consumption (Watts), output current (Amps), heat dissipation (BTU/Hr). It tcomes up with a list of recommended power supplies, and give you a quick graphical representation of the power usage based on the installed supply (presumably, orange is not good):
I’ve upgraded to the new release of wordpress (”ella”) and updated my theme as well. The theme I’m using now is much simpler to work with than k2, and given that my priority was to be up and running without first knowing all the ins and outs of wordpress/css/php and so on, this is a better fit. I’ll continue tinkering with appearance and functionality and slowly continue to get more up to speed on the web dev side of things. I had been looking into a good Linux html/php editor (briefly tested bluefish, quanta, screem, nvu) but I’m going to give WP’s 2.1 built-in editor a shot. For one thing, the auto-save feature is, believe or not, something new in this release that I was really missing.
Summary:
For my own rerence and your delectation, I’m going to talk about the Cisco IOS “show history” command use and defaults, with a brief comparison to Unix-type “history” plus grep. Following that, I’ll discuss changing the history buffer size for a single session, writing the buffer size change to config, and how to display the currently configured history buffer size. Commands used:
show historyterminal history size 50(config-line)#history size 50show terminalA few things are looking better on the site now. I uninstalled then re-installed K2, and a few glaring problems were fixed.
Clearly, I need to figure out this K2 theme and scheme. Page not found? I’m not sure where that’s coming from.
Humph. Never fear. Got a new year, forgot to eat my lucky foods, but torpedoes be damned. I’ll have something useful up here, pronto quick (relatively speaking) and banish the errors before you can read the wikipedia entry on Gödel’s incompleteness theorem and write a rebuttal in Esperanto. Warning: quick (grammatically speaking ‘quickly’) may be in cosmological time.
New year’s resolution: get cracking, study, write up some summaries.
