power unit and a monitoring unit.
ESD Jack
The ESD jack of the EA5800-X7 service subrack is on the bottom 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-X7 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-X7 subrack has 2 ground points. One is on the side panel
and the other is at the middle of the right mounting bracket of the
subrack.
The power input end of the EA5800-X7 has a noise filter. The center
ground of the noise filter connects to the subrack, called the
chassis shell ground, that is, the protection ground. Ground the
subrack shell securely so that the influence electricity, leakage
electricity can flow to the ground, improving the protection
against electromagnetic interference.
Use a ground cable to connect the ground point of the subrack shell
to the ground bar of the telecommunications room or to the ground
directly. It is recommended that the grounding resistance of the
telecommunications room should be less than 10 ohms. Refer to the
local standards to ground the subrack.
Physical Parameters
This topic provides the dimensions, weight, power supply
parameters, and power consumption of the EA5800-X7 service subrack.

Power Consumption
Power consumption of the EA5800-X7 service subrack (Unit: W)
Typical Configuration | Static power consumption | Maximum power consumption | Typical power consumption | Board configuration |
GPON | 296 | 721 | 508.5 | H902MPLAE*2+H901PILA*2+H901FMMA+H901GPSFE*7 |
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.
The preceding table lists power consumption under typical
configuration. For power consumption under other configurations,
use Access Network Hardware Configuration Tool.
Slot Configuration
An EA5800-X7 service subrack provides 12 slots, including 2 slots
for control boards, 2 slots for power boards, 1 slot for the
universal interface board, and 7 slots for service boards.
H901BPMB is the backplane supported by the EA5800-X7.
Fan Tray
The fan tray of the EA5800-X7 service subrack has six fans and fan
monitoring board H901FMMA, and functions heat dissipation,
monitoring, and fan speed adjustment, which ensures that the device
works at a stable temperature.
The functions of the fan tray are as follows:
Heat dissipation
The fan tray is at the right of the service subrack and exhausts
hot air for heat dissipation. The cool air flows to the subrack
from the left of the subrack and then is exhausted from the right
of the subrack after passing the boards.
Monitoring
The fan tray is configured with the fan monitoring board to detect
whether the fans are working in the normal state. The fan
monitoring board also provides the port for communication with the
control board. The detected information is transmitted to the
control board through the fan monitoring board periodically.
Speed adjustment
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
Control-system-triggering: The control system automatically adjusts
the fan speed according to the board temperatures for energy
conservation.
Monitoring-board-triggering: The control system adjusts the fan
speed according to the temperature information collected by the
monitoring board.
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%.
