1.5 1.5.9 UBIC-H EIA
If you are installing UBIC-H EIAs after the shelf assembly is installed, plug the UBIC-H EIA into the
backplane. The UBIC-H backplane must replace the standard sheet metal cover to provide access to the
cable connectors. The UBIC-H sheet metal covers use the same screw holes as the standard sheet metal
covers, but they have 12 additional holes for panhead screws and three holes for jack screws so you can
screw down the cover and the board using standoffs on the UBIC-H board.
When installed with the standard door and cabling on the backplane, the ONS 15454 shelf measures
approximately 14.5 inches deep when fully populated with backplane cables, and 15.0 inches deep with
the rear cover installed. When installed with the deep door and cabling on the backplane, the ONS 15454
shelf measures approximately 16.5 inches deep when fully populated with backplane cables, and 17.0
inches deep with the rear cover installed.
The UBIC-H EIA supports the following cards:
• DS1-14, DS1N-14
• DS3-12, DS3N-12
• DS3-12E, DS3N-12E
• EC1-12
• DS3XM-6
• DS3XM-12
• DS3/EC1-48
• DS1/E1-56
