Position Of Components in the Cabinet
The position of the IOX components - ICE, XUC, RDM and XPC - is independent of rack position. The are no
mechanical, thermal or cabling limitations that affect the rack position of any of the components. There are
however, supportability and ergonomic considerations that influence component position in the cabinet.
Since the CPA (on the XUC) and RDM display user information including cabinet number, they should be
placed where the user can view the information easily. The RDM is installed directly behind the XUC.
The ICE requires access from the side, so it should be placed where OL* of PCI cards and other service
operations can be performed easily, preferably not at the bottom of the cabinet.
IMPORTANT To facilitate service access, an ICE must not be installed at the top of a 1.96m cabinet. It should
not be installed at the bottom of the rack, because the alignment and installation of horizontal
PCI cards installed at the bottom of the rack can be problematic.
The BPSs are relatively heavy FRUs. Therefore, the lower the XPC is installed in the cabinet, the more
cabinet stability is improved. Additionally, hoisting a BPS to a high position in the field can be difficult for
some.
