48V DC Terminal server recommendations

[Jeremy Bresley <brez () brezworks com>]

Looking for recommendations on a good terminal server to put into a 
telco colocate facility.

Requirements:
8-16 ports for Cisco console access (RJ-45s preferred, DB9s if we have to)
-48V DC power
USB/internal modem for OOB access
NEBS Level 1 (or better) compliance.

So far I've found Perle has several models that meet 3 out of 4, but 
none that meet all the requirements.  The only OpenGear boxes we're 
seeing with DC power is a little 4 port unit and they don't mention NEBS 
compliance.  Lantronix mentions DC power for their SLC line, but doesn't 
mention anything about NEBS compliance either.

Anybody have any recommendations for one they've used that meets all 4 
of those requirements?

Thanks!
