Hello Groupstudy,
I just joined the list but I have been searching the archives for the last
year while studying for the written. I am studying for the CCIE lab now and
have purchased almost all the equipment I will need.
I have a question about providing power for my home lab. I live in an
apartment with several free outlets around the place, ranging from 15 to 30
AMPS according to the circuit breaker box. They are well labeled by the way.
Below are my devices and their power ratings. I got these ratings from the
devices themselves and in case of the 3640s from here:
http://www.cisco.com/en/US/products/hw/routers/ps274/products_data_sheet09186a0080091f6f.html
2x3560 switches, rating: 1.3-8amps (total: 2.6-16 amps
2x3550 switches, rating: 5.5/2.8 (total 2x5.5 for 11 amps)
5x2500 routers, rating: 40W 1.2-0.6A (total: 3 amps)
6x3640 routers, rating: AC input: 2 AMPS (total: 12 amps)
totals
switches: 17-27 amps
routers: ~15 amps
I don't have a dryer or washer and the washer room has 2x30amp outlets.
Should I build my lab in the washer room? Should I run an extension cord
from the washer to my bedroom, a distance of about 35 feet? I have air
conditioning by the way in the bedroom but not in the washer room.
Are there any other considerations I should take into account? I do plan on
getting a UPS/line conditioner (i believe this is the correct term) but I
believe I still need to take into account the overall power I am drawing
from the outlets.
I am not an electrical guru by any means, so if I am misunderstanding these
ratings please let me know. Any advice would be appreciated.
I found so many answers searching through your archives, it is really a
pleasure to have such a valuable resource.
Thank you,
-DH
