16CHAPTER 1: PRODUCT OVERVIEW

Role and function

The MBUS system is powered by 5 V from the MBUS on the fabric. The 5 V power on the two fabrics are redundant to each other.

Each MBUS module is attached to the MBUS, which contains two control lines:

MBUS0 and MBUS1.

Each card has an independent MBUS module, those on the fabrics are primary

MBUS modules, and those on application modules are secondary MBUS modules.

When the fabrics operate in redundancy mode, the MBUS module on the active fabric is the active module, and the one on the standby fabric is the standby module.

The MBUS uses a controller area network (CAN) bus as its control bus, that uses the 1:1 hot backup and transfers control information at 1 Mbps.

Fan Tray ■ The Switch 8807 uses one 25 W fan tray, which contains four 120 x 120 x 25.4

mm(4.7 x 4.7 x 1.0 in.) axial fan units. The fans can be governed in two modes: fabric-controlled or temperature-controlled. They operate at -48 VDC supplied from the backplane.

■The Switch 8810 uses one 35 W fan tray, which contains six 120 x 120 x 25.4

mm(4.7 x 4.7 x 1.0 in.) axial fan units. The fans can be governed in two modes: fabric-controlled or temperature-controlled. They operate at -48 VDC supplied from the backplane.

■The Switch 8814 uses two 25 W fan trays, each of which contains four 120 x 120 x 25.4 mm (4.7 x 4.7 x 1.0 in.) axial fan units (and totally eight for the two fan trays). The fans can be governed in two modes: fabric-controlled or temperature-controlled. They operate at -48 VDC supplied from the backplane.
