The ESD jack of the EA5800-X17 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.
NOTICE:
Connect the ground cables properly to guarantee protection against lightening and interference for the EA5800-X17 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.
The EA5800-X17 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.

Power Supply
Table 2 Power supply parameters of the EA5800-X17 service subrack
Parameter | Specification |
Power supply mode | DC (dual power for backup) |
Rated voltage | -48 V / -60 V |
Working voltage range | -38.4 V to -72 V |
Maximum input current | 60 A |
Power Consumption
Table 3 Power consumption of the EA5800-X17 service subrack (Unit: W)
Typical Configuration | Static power consumption | Maximum power consumption | Typical power consumption | Board configuration |
GPON | 569 | 1196 | 882.5 | H902MPLAE*2+H901OGHK+H901PILA*2+H901FMLA+H901GPSFE*16 |
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-X17 service subrack provides 22 slots, including 2 slots for control boards, 2 slots for power boards, 1 slot for the universal interface board, and 17 slots for service boards.
H901BPLB is the backplane supported by the EA5800-X17 service subrack.

Fan Tray
The fan tray of the EA5800-X17 service subrack has eight 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.
Specification
Function
The functions of the fan tray are as follows:
Heat dissipation
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.
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 20% to 100%.
Heat Dissipation
This topic describes the ventilation of the EA5800-X17 service subrack.
The EA5800-X17 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-X17 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-X17 service subrack.Figure 1 shows the heat dissipation of the EA5800-X17 service subrack.
