Parameters

Board Parameter

You can query power consumption, weight, maximum frame size, and normal operating temperature of all boards.

Table 1 lists the power consumption, weight, and maximum frame size of boards.

The operating temperature of H901XSED and H901TWED is -40°C to +55°C (in MA5800–X17/X15/X7) or -40°C to +65°C (in MA5800–X2) and the lowest board startup temperature is -25°C. The operating temperature of other boards is -40°C to +65°C and the lowest board startup temperature is -25°C.

NOTE:

The power consumption of a board is calculated based on the following conditions:

Operating voltage: -53.5 V DC.

Ambient temperature: 25°C.

Static power consumption: All ports do not carry any loads and optical modules are not installed on optical ports.

Maximum power consumption: All ports fully carry loads.

The board power consumption slightly varies with the power module configured for the board and discreteness of components.
