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.
Table 1 Power consumption and maximum frame size of boards
Board | Power Consumption | Weight | Maximum Frame Size |
Upstream interface board | |||
H901NXED | Static: 40 W Maximum: 53 W | 0.99 kg | 2052 bytes. After the jumbo frame function is enabled, a maximum of 9216 bytes can be supported. |

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.
Indicator
Indicator | Name | Status | Operation Description |
RUN/ALM | Running status indicator | Red: blinks | The board enters the APP start phase during the board startup |
Green: blinks every 0.25s | The board enters the phase of communication with the control board during its startup | ||
Green: blinks every 1s | The board works in the normal state | ||
Orange: blinks | A high-temperature alarm is generated | ||
Red: on | The board is faulty | ||
LINK/ACT 0-7 | Ethernet link status indicator | Green: on | The link is normal |
Green: blinks | Data is being transmitted | ||
off | The port is not connected |
