The EA5800-X2 service subrack is 2 U high, and has a fan tray at
the right. The subrack is installed in the cabinet through the
mounting brackets.
ESD Jack
The ESD jack of the EA5800-X2 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-X2 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-X2 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-X2 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-X2 service subrack.
Dimensions and Weight
Table 1 Dimensions and weight of the EA5800-X2
Item | Specification |

Maximum fully-loaded weight (including mounting ears of IEC
standard) | 9.4 kg |
Power Supply
Table 2 Power supply parameters of the EA5800-X2
Parameter | Specification |
Power supply mode | DC (dual power for backup)/AC power + battery |
Rated voltage | DC power: -48 V/-60 V AC power: 110 V/220 V |
Working voltage range | DC power: -38.4 V to -72 V AC power: 100 V to 240 V |
Maximum input current | DC power: 20 A AC power: 8 A |
Power Consumption
Table 3 Power consumption of the EA5800-X2 service subrack (Unit:
W)
Typical Configuration | Static power consumption | Maximum power consumption | Typical power consumption | Board configuration |
GPON | 164.5 | 299.5 | 232.0 | H901MPSCE*2+H901GPSFE*2+H901PISA+H901FMSA |
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.
An EA5800-X2 service subrack provides 5 slots, including 2 slots
for control boards, 1 slot for power board, and 2 slots for service
boards.
H901BPSB is the backplane supported by the EA5800-X2.
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-X2 service
subrack.
The EA5800-X2 service subrack has a fan tray at the right side to
exhaust hot air for heat dissipation.
The airflow is as follows: The cool air enters the EA5800-X2
service subrack at the left side, and is blown towards the right
side by the fans, and finally, exits at the right side of the
EA5800-X2 service subrack.Figure 1 shows the heat dissipation of
the EA5800-X2 service subrack.
