The ORIGIN master section bucket may be rearranged and also accept standard 19" rack devices, such as UF1.
Cable egress is via the bottom of the console — you may remove or loosen the small rectangular bottom panel towards the back.
Please see the "MOVING THE MASTER SECTION" in the Install Guide for a drawing showing cable egress. You may also search the word cable access to highlight those references.
You may find it easier to connect cables before fitting rack equipment.
