Appearance and Structure
The MA5800-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 MA5800-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.
MA5800-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.
The power input end of the MA5800-X15 subrack has a noise filter. The center ground of the noise filter connects to the subrack, called the subrack ground, that is, the protection ground. Ground the subrack 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 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.

This topic provides the dimensions, weight, power supply specifications and power consumption of the MA5800-X15 service subrack.
Dimensions and Weight
|Dimensions (H x W x D, including mounting ears)||486 mm x 482.6 mm x 287 mm|
|Dimensions (H x W x D, excluding mounting ears)||486 mm x 442 mm x 287 mm|
|Maximum weight at full configuration (including mounting ears)||35 kg|
Power supply specifications of the MA5800-X15 service subrack
|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|
|Typical Configuration||Static power consumption||Maximum power consumption||Typical power consumption||Board configuration|
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.
- In the case of Access device, power consumption is generally transformed into heat consumption. Hence, heat consumption (BTU/h) and power consumption (W) can be converted to each other in the formula: 1 BTU/h = 0.2931 W
