[labnetwork] Fwd: Interlock Boxes

Wed Oct 1 14:06:36 EDT 2014

Todd,

Thanks for the interlock system, It was really helpful. I guess each equipment in the cleanroom is equipped with interlock, so you run network cable to unit, Do you ever thought of using the wireless router to do this. Will the Wireless router signal might interfere your sensitive equipment.
Is there any specific network cable you use or regular CAT5 / CAT6 cable is sufficient. Our cleanroom is built without any network port, if I want to do this I have to physically run cable on the ceiling in the chase and drop it next to the equipment. 

--Thanks

Here are some user account issues that we had in the Berkeley Microlab ( I'm not sure if they are still relevant to the Marvel Nanolab in 2014).

The Marvell Nanolab maintains it's own user database for the following
reasons:  Note, the Nanolab network is administered by the EECS department.

a) The EECS departmental database does not allow account creation of users from other departments without a monthly fee (so members would be billed for two departments in that case).

b) The EECS department doesn't want non paying customers using their network.

c) The campus database does not allow outside industry members to acquire an account without legalese that industry members find unacceptable.

d) Guest users require limited access to layout conversion software ( for mask making) or view only privileges of equipment maintenance, process monitoring, and other database tables. So paying a network access fee is out of the question.

P.S. A web based interlock system used in some rooms by the Microlab was from WebRelay http://www.controlbyweb.com/webrelay/
