H801SPUB Board
The H801SPUB board is a MPLS service processing unit board.
Feature and Specifications
10 Gbit/s MPLS switching capability
Unidirectional 10 Gbit/s, bidirectional 5 Gbit/s when only one
control board (SCUx) is working
Bidirectional 10 Gbit/s when two control boards (SCUx) are working
in load sharing mode (V800R011C00 and later versions)
Active/standby switchover of the control boards
Board power-off in case of a high temperature
Temperature query and high-temperature alarm
NOTE:
Only two SPUB boards can be installed in the system at the same
time. And if two SPUB boards are in use, both of them must be
located side by side in the shelf.
Parameters
Power Consumption and Maximum Frame Size of Boards
You can query power consumption, maximum frame size, and normal
operating temperature of all boards.
lists the power consumption and maximum frame size of boards. "-"
indicates N/A.
The operating temperature of all the boards is -40°C to +65°C. The
lowest board startup temperature is -25°C.
NOTE:
The power consumption of the board is tested in the following
conditions:
Working voltage: -53.5 V DC.
Ambient temperature: 25 °C.
Static power consumption: All ports do not carry any loads.
Specifically, users under POTS ports hang up phones, xDSL ports are
deactivated, and optical modules are not installed on optical ports
Maximum power consumption: All ports fully carry loads. However,
only 25% users under POTS ports concurrently pick up phones and the
feeding current is 20 mA.
The board power consumption slightly varies with the power module
configured for the board and discreteness of components.

Working Principle
Figure 1 Working principle of the H801SPUB board
The basic working principle of the H801SPUB board is as follows:
The control module loads the board software, controls the running
of the board, and manages the entire board.
The service processing module processes the MPLS packets and the
service data packets, and forwards the service data packets.
The power module draws -48 V power from the backplane and converts
the power into working power for each functional module of the
board.
The clock module provides clock signals for each functional module
of the board.

Indicator
Indicator | Name | Status | Meaning |
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 |
ACT | Active indicator | Green: on | This board is active |
Yellow: on | This board works in the load-balancing mode |
Off | This board is standby |
