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.
