Appearance and Structure

The EA5800-X7 service subrack has a fan tray on the right side. The subrack can be installed in the cabinet using the ETSI or IEC mounting brackets.

 

ESD Jack

The ESD jack of the EA5800-X7 service subrack is on the bottom of the fan tray and is used to connect the ESD wrist strap to prevent device damage caused by electrostatic discharge.

Grounding

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, a separate ground cable is needed to connect the service subrack to the ground point on the cabinet.

The EA5800-X7 subrack has 2 ground points. One is on the left side panel and the other is in 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, known as the chassis ground or protection ground. Ground the subrack enclosure securely to divert the induced or leaked current to the ground and improve the protection against electromagnetic interference.

Use a ground cable to connect the ground point of the subrack enclosure 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 before grounding the subrack.

Table 3 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 are idle, and no optical module is inserted to any optical port.
• Maximum power consumption: All ports are running at full capacity.
• Typical power consumption: half of the total value of the static power consumption and maximum power consumption.
• To calculate the actual power consumption, use the Access Network Hardware Configuration Tool.
• The power consumption of access devices is generally transformed into heat consumption. Therefore, heat consumption (BTU/h) and power consumption (W) can be converted to each other using this formula: 1 BTU/h = 0.2931 W.

Slot Configuration

An EA5800-X7 service subrack provides 12 slots, 2 for control boards, 2 for power boards, 1 for the universal interface board, and 7 for service boards.

H901BPMB is the backplane supported by the EA5800-X7.

Table 1 Slot description

Slot Type	Slot	Supported Board	Remarks
Control board slot	8,9	Control board	The active and standby control boards must be configured, and the 2 boards must be of the same type.
Power board slot	10,11	Power board	-
Universal interface board slot	0	Universal interface board	-
Service board slot	1-7	Uplink interface board Service board	Different types of service boards can be configured together. You can use a control board or uplink interface board for upstream transmission. However, it is recommended that you use a control board for upstream transmission.

Fan Tray

The fan tray of the EA5800-X7 service subrack has 6 fans and a fan monitoring board FMMA and supports heat dissipation, monitoring, and fan speed adjustment to ensure that the device works at a proper temperature.

Specification

Item	Specification
Dimensions (H x W x D)	43.6 mm x 257.5 mm x 260.4 mm
Weight	2.00 kg (Fan tray)
Power consumption	Static: 14 W Maximum: 189 W

 NOTE:

The power consumption of access devices is generally transformed into heat consumption. Therefore, heat consumption (BTU/h) and power consumption (W) can be converted to each other using this formula: 1 BTU/h = 0.2931 W.

Function

The functions of the fan tray are as follows:

• Heat dissipationThe fan tray is on the right side of the service subrack to exhaust hot air. The air flow is from left to right.

• MonitoringThe fan monitoring board detects whether the fans are working in a normal state and sends the results to the control board periodically.

• Speed adjustmentThe rotating speed of the fans can be adjusted manually or automatically based on the detected temperature.

Indicator

Indicator	Color	Status	Meaning	Operation Description

Indicator	Color	Status	Meaning	Operation Description
STATUS	Yellow	Blinking quickly (on for 0.125 s and off for 0.125 s repeatedly)	The fan tray is not registered, is being loaded, or fails to communicate with the control board.	If the fan tray is not registered or is being loaded, no action is required. If the fan tray fails to communicate with the control board, check the communication connection between the fan tray and the control board.
	Green	Blinking	The fan tray works in the normal state.	No action is required.
	Yellow	Blinking slowly (on for 1 s and off for 1 s repeatedly)	The fan tray generates alarms that do not affect services.	Handle it based on the corresponding alarm.
	Red	Blinking	The fan tray is faulty or the fan tray generates an over-temperature alarm.	Replace the faulty fan tray. Increase the fan speed to lower the temperature.

Fan Speed Adjustment

The fan speed adjustment mode can be set to "automatic" or "manual" in the command line interface (CLI). The default mode is "automatic".

 NOTE:

The fan tray is used for heat dissipation of the system so that the device can work at a normal temperature. When the ambient temperature exceeds the upper limit, the system automatically reports a high temperature alarm.

• Automatic mode
  • Based on the control system: The control system automatically adjusts the fan speed according to the board temperatures for energy conservation.
  • Based on the monitoring board: The control system adjusts the fan speed based on the temperature information collected by the monitoring board.
   NOTE:

  When the automatic speed adjustment mode is used, the device automatically switches between adjustment based on the control system and the adjustment based on the monitoring board.

• Manual modeYou can also manually adjust the fan speed to a level between level 0 (the lowest speed) and level 6 (the highest speed) or a percentage between 20% and 100% using commands.
