What is the meaning of E-PBC in an enclosure?

Re: Drive Enclosure
Hi,
I take it you know how to use Google...!
RoHS:
Restriction of Hazardous Substances
http://www.rohs.gov.uk/
A European Directive restricting the sale/movemenent of electronic/electrical goods with more than agreed levels of certain harmful chemicals (lead, cadmium etc.)
E-PBC:
Would appear to be a similar Australian directive.
http://www.environment.gov.au/epbc/index.html
When used in relation to a drive enclosure, it probably just means that the components conform to these directives.
Hope this helps,
Regards,
Rob

Hi,
Rohs- yes that is correct,
E-PBC - sorry no nothing to do with hazourdous substances.
E-PBC = Enhanced Port Bypass Chip. You find this on Rev E I/O modules for EVA shelves. You must use these for the second generation EVA products [4/6/8k] but they can be used in the first generation as well. They have a new chip built into them that monitors the bus for errors. When these errors/thresholds are reached then the I/O module will port bypass the failing drive. Makes the backend loops more reliable for "mapping" out failed drives as opposed to the drives mapping themselves should they fail. You do not require an SFP in the bottom port if they are used in a switched config - REV D/C modules require SFP's installed even if not used.
That's about it really.
