H901NXED Board Description

The H901NXED board is an 8-port optical uplink interface card that provides upstream optical ports.

Feature and Specifications

The H901NXED board supports the following features and specifications:

8 ETH SFP ports that support 10GE/GE optical modules

Line clock used as the system clock

A maximum of 80 Gbit/s non-convergence upstream bandwidth

Ethernet clock synchronization

Temperature query and high temperature alarm

Automatic power shutdown in case of a high temperature

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.

For details about supported optical module, see 10GE Optical Module and GE Optical/Electrical Module.

 NOTE:

Default transmission rate of the upstream port is 10000 Mbit/s (10GE), which can be set to 1000 Mbit/s (GE) by running the speed command.
