Shelves

Shelf is an empty box in which different cards are plugged-in. ZXMSG 5200 has one main and four expansion shelves. Both the main shelf and slave shelves use the same shelf type based on the selection of cabinet, access type and power redundancy requirement. ZXMSG 5200 has the following shelf types:

• Standard shelves

− Single power rear access standard shelf (6U)

− Dual power rear access standard shelf (6U)

− Dual power front access standard shelf (9U)

• ONU100 mini shelf

• OUT50F shelf

• OUT50C mini shelf

• OUT50D mini shelf

Among the standard shelves, rear access shelf can be installed in indoor cabinet 19D06H20, 1500E and outdoor cabinet OUT40E, OUT20E. And front access shelf can be installed in indoor cabinet 19D06H20, 1500E and outdoor cabinet OUT40E, OUT60, OUT20E. ONU100 mini shelf is especially is ONU100 cabinet, and OUT50F/C/D mini shelf is especially for OUT50F/C/D.

4.2.3.1 Single Power Rear Access Standard Shelf

Single power rear access standard shelf offers 17 effective slots for holding major boards such as POWER H board, user interface boards, control switching board ICS, VoIP processing board MPRB, and test board TSLC. The POWER H can work together with the POWER H in another unit in the same rack/cabinet to make inter-layer power backup.
