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.

Power Supply
Table 2 Power supply parameters of the EA5800-X15 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-X15 service subrack (Unit:
W)
Typical Configuration | Static power consumption | Maximum power consumption | Typical power consumption | Board configuration |
GPON | 513 | 1182 | 847.5 | H902MPLAE*2+H901OGHK+H901PILA*2+H901FMLA+H901GPSFE*14 |
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.
