Huawei EA5800-X15 OLT Service Subrack with MA5800 MA5600 XEBD XGBD GPBD GPHF EPSD GPFD EPFD XEBD XGBD GPBD GPHF EPSD GPFD EPFD

 The EA5800-X15 service subrack provides 20 slots, and has a fan tray at the top. The subrack is installed in the cabinet through the mounting brackets.

The ESD jack of the EA5800-X15 subrack is on the left of the fan tray, which is used to connect the ESD wrist strap to prevent device damage caused by electrostatic discharge.

Grounding

 NOTICE:

Connect the ground cables properly to guarantee protection against lightening and interference for the EA5800-X15 subrack. When a Huawei cabinet is installed, the service subrack is grounded through mounting ears and therefore no separate ground cables are required. When a third-party cabinet is installed, the separate ground cable needs to be connected to the service subrack and ground point on the cabinet.

EA5800-X15 subrack has 2 ground points. One is on the side panel and the other is at the bottom of the right mounting ear of the subrack. 

Physical Parameters

This topic provides the dimensions, weight, power supply parameters and power consumption of the EA5800-X15 service subrack.

Dimensions and Weight

Power Consumption

Table 3 Power consumption of the EA5800-X15 service subrack (Unit: W)

 NOTE:

The power consumption of a service subrack 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.

Typical power consumption: half of the total value of static power consumption and maximum power consumption.

Slot Configuration

An EA5800-X15 service subrack provides 20 slots, including 2 slots for control boards, 2 slots for power boards, 1 slot for the universal interface board, and 15 slots for service boards.

H901BPIB is the backplane supported by the EA5800-X15 service subrack.

Fan Tray

The fan tray of the EA5800-X15 service subrack has six fans and fan monitoring board H901FMLA, and functions heat dissipation, monitoring, and fan speed adjustment, which ensures that the device works at a stable temperature.

Figure 1 Appearance 

The functions of the fan tray are as follows:

The rotating speed of the fans can be adjusted according to the detected temperature automatically or be adjusted by setting the related data manually.

Indicator

Fan Speed Adjustment

Set the fan speed adjustment mode to "automatic" or "manual" in the command line interface (CLI). After the fans are installed, they work in automatic mode by default.

Automatic mode

 NOTE:

The automatic mode has two variants (automatically selected by the system): control-system-triggering and monitoring-board-triggering.

Manual mode

Commands are executed to adjust the fan speed. The levels range from 0 to 6, level 0 being the lowest speed and level 6 being the highest speed. Alternatively, the fan speed can be set from 30% to 100%. 

Heat Dissipation

This topic describes the ventilation of the EA5800-X15 service subrack.

The EA5800-X15 service subrack has a fan tray at the top to exhaust hot air for heat dissipation.

The airflow is as follows: The cool air enters the EA5800-X15 service subrack at the bottom, and is blown towards the top side by the fans, and finally, exits at the top side of the EA5800-X15 service subrack.Figure 1 shows the heat dissipation of the EA5800-X15 service subrack.
