3.2 Powering On the Indoor Device
This topic describes how to power on the indoor device to ensure that each board is supplied with power in the normal state.
Prerequisite
l The installation check and the power-on check must be performed on the device.
l All the input power and the output control switches of the DC PDU must be turned off.
Procedure
Step 1 Turn on the input power of the DC PDU.
Step 2 Turn on the output control switches of the DC PDU.
----End
Result
The LED of the control board blinks 1s on and 1s off repeatedly.
3.3 Powering On the Outdoor Device
This topic describes how to power on the outdoor device to ensure that each board is supplied with power in the normal state.
Prerequisite
l The installation check and the power-on check must be performed on the device.
l The power switch of the lightning arrester, the input/output switches of the GEPS4860, and the power switch of the heating panel must be turned off.
Procedure
Step 1 Turn off the AC power input switch to power on the lightning arrester.
Step 2 Turn off the MCB "AC POWER" to power on the GEPS4860.
Step 3 When the device temperature is lower than -25°C, turn on the miniature circuit breaker (MCB) of the heating panel to heat the device components until the device temperature is higher than -25°C. When the device temperature is higher than -25°C, skip this step.
NOTE
When the device starts at the temperature lower than -25°C, use the heating panel to heat all the components to -25°C above, and then the device can be powered on.
Step 4 Turn on the AC input MCB on the GEPS4860 (set the MCB upward). In the normal state, after a short delay, the RUN LEDs on the front panels of all the rectifier units are green after the rectifiers units are started. The RUN LED on the monitoring unit blinks slowly in green, and the ALM LED is on.
Step 5 Turn on all the load MCBs on the GEPS4860 (set the MCBs upward). In the normal state, the ALM LED on the front panel of the monitoring unit is off.
Step 6 Turn on (set the switch upward) the power switch on the GEPS4860 to supply power for the heat exchanger.
Step 7 Turn on (set the MCB upward) the MCB "BATT" on the GEPS4860 to supply power for batteries.
----End
Result
The RUN LED on the control board blinks 1s on and 1s off repeatedly.
3.4 Commissioning the Power System
This topic describes how to commission the reliability of the power supply system so that the system can supply the power to the device in the normal state.
3.4.1 Checking the Power Supply of DC PDU
This topic describes how to check whether each power input which supports mutual backup can supply power to the cabinet independently through the two or four power inputs.
Prerequisite
The two or four power inputs of the DC PDU supply power to the cabinet at the same time
Procedure
l Please implement the following steps when the two independent power supplies works in the normal state for the cabinet:
1. Disconnect power input A of the DC PDU and check the power supply of the cabinet.
2. Restore the power supply of power input A to the cabinet.
3. Disconnect power input B of the DC PDU and check the power supply of the cabinet.
4. Restore the power supply of power input B to the cabinet.
l When the four power inputs supply power to the cabinet in the normal state, usually adopt the mutual backup. That is, A and B mutually backup for each other, C and D mutually backup for each other, please implement the following steps:
1. Disconnect the power supply of power input A and C of the DC PDU and check the power supply of the cabinet.
2. Restore the power supply of power input A and C to the cabinet.
3. Disconnect power input B and D of the DC PDU and check the power supply of the cabinet.
4. Restore the power supply of power input B and D to the cabinet.
----End
Result
After disconnecting the backup power supply of any power input, the power supply and the service of the device board stay unaffected.
3.4.2 Checking the Power Supply of AC Power Module
This topic describes how to check whether other rectifier units can supply power to the cabinet in the normal state when the rectifier unit of the AC power is configured redundantly and one rectifier unit is faulty.
Prerequisite
The AC mode is used in the cabinet for power supply.
Procedure
Step 1 Remove a rectifier unit and check the power supply of the cabinet.
Step 2 Insert the rectifier unit back into the cabinet.
NOTE
Repeat step 1 and step 2 to verify one by one whether other redundant rectifier units are normal.
----End
Result
After removing any rectifier unit, the power supply and the service of the device board stay unaffected.
3.4.3 Configuring the Battery and Checking the Power Supply of the Battery
This topic describes how to configure the battery and verify whether the backup power supplied by the battery to the AC power system is in the normal state.
Prerequisite
The cabinet must adopt the AC power supply and must be configured with the battery.
Context
l Currently, the encapsulated valve regulated lead acid (VRLA) batteries used in the communication industry are all produced in full loading state, that is, the battery has been charged with electricity fully.
l Based on the battery features, automatic discharge will occur due to chemical reaction during the delivery and storage process. In this case, the battery capacity and the open circuit voltage decrease. We refer to this phenomenon as the automatic charge of the battery.
In a certain period, if you use appropriate methods, the voltage and the capacity of the battery can be restored completely.
l To make up the automatic discharge during the idle period, you need to perform the supplementary charge for the battery in long idleness periodically. For this type of situation, refer to "Operation Guide on Battery Supplementary Charge" to complete the
supplementary charge of the battery first, and then perform the following commissioning procedures.
Procedure
Step 1 In global config mode, run the emu add command to add the EMU of the power system.
Step 2 In global config mode, run the display emu command to query whether the status of the power system shows normal.
Step 3 Run the interface emu command to enter the EMU mode to configure the battery parameters.
CAUTION
The battery capacity parameters corresponding with different cabinets are different. You need to configure in correct way. Otherwise, you may damage the battery.
Step 4 In the corresponding power mode, run the power battery command to configure the battery parameters.
Table 3-13 lists the battery capacity of the different cabinets in the UA5000.
Table 3-13 Battery capacity of different cabinets
Cabinet Type Battery Capacity
ONU-F01E200 (Outdoor) 50 AH
ONU-F01E400 (Outdoor) 75 AH
ONU-F01D200 (Outdoor) 80 AH
ONU-F01D500 (Outdoor) 150 AH/184 AH
ONU-F01D1000 (Outdoor) 184 AH
ONU-F02A (Indoor) 100 AH
Step 5 In the corresponding power mode, run the power battery-test command to configure the battery discharging parameters.
Step 6 In privilege mode, run the save command to save the related configuration. When the monitoring module and the UA5000 device communicate with each other in the normal state, the configured data take effect automatically.
Step 7 Disconnect the mains supply, and check whether the cabinet power system can switch to the battery supply mode.
Step 8 Restore the mains supply, and check whether the cabinet power system can switch to the mains
Step 8 Restore the mains supply, and check whether the cabinet power system can switch to the mains
