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 |
Dimensions (H x W x D, excluding mounting ears) | 88.1 mm x 442.0 mm x 268.7 mm |
Dimensions (H x W x D, including mounting ears of IEC standard) | 88.1 mm x 482.6 mm x 268.7 mm |
Dimensions (H x W x D, including mounting ears of ETSI standard) | 88.1 mm x 535.0 mm x 268.7 mm |
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.
