H801X2CS Board
The H801X2CS board is a 2-port 10GE uplink interface card that
provides two 10GE upstream or cascading optical ports.
Feature and Specifications
Upstream Interface Boards Comparison
The device supports GE and 10GE upstream interface boards.
In the table, "Yes" indicates "supported" and "No" indicates "not
supported".
Table 1 Specifications lists of upstream interface boards
Board | Upstream Transmission (*) | Cascading (*) | Intra-board aggregation and Inter-board aggregation | Clock Feature | Port | Pluggable Optical Module | Pluggable Electrical Module |
H801X2CS | Yes | Yes | Yes | 10 GE synchronous Ethernet | Two 10GE ports | SFP+ | No |
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.
Table 1 Power consumption and maximum frame size of boards
Board | Power Consumption | Maximum Frame Size |
Upstream interface board (GIU) |
H801X2CS | Static: 17.6 W Maximum: 18 W | 2052 bytes. After the jumbo frame function is enabled, a maximum of
9216 bytes can be supported. |
Working Principle
The control module reports the status of and manufacturing
information about the board, and provides the interface
information. The control module also manages the modules on the
board, and processes alarms.
The interface module provides two 10GE ports.
The synchronization Ethernet clock module extracts clock signals
from the 10GE signals, and synchronizes the 8 kHz clock of the
control board with the clock signals.
The power module supplies power to other functional modules of the
board.
The clock module provides clock signals for other functional
modules of the board.
