Verifying power supply module operation
4.
Make sure that the latch snaps into place in the chassis.
5.
Reconnect the power lugs to the power supply unit by connecting the -48V wire to the negative terminal and the 0V wire to the
positive terminal.
NOTE
The DC return must be isolated from the device ground (DC-I) when making connections to the power supply.
6.
Replace the safety cover.
7.
Reattach the power cord to the power source.
8.
Verify that the power LED on the power supply displays a steady green light.
NOTE
This equipment installation must meet NEC/CEC code requirements. Consult local authorities for regulations.
Verifying power supply module operation
To verify operation of a power supply assembly, perform the following procedure.
1.
Check the LEDs on the power supply module front panel. For information about interpreting LED patterns, refer to
power supply module LEDs
2.
Enter the following commands and note any error conditions:
•
show environment power - Displays the current status of the power supply.
•
show system - Displays information of each component in the system.
High Voltage Power Supply Unit supporting AC and
DC Voltages
The SLX 9850-4 supports High Voltage Power Supply Unit (PSU). It is a single PSU that can operate both High Voltage AC (HV AC)
and High Voltage DC (HV DC) in the ranges shown below:
TABLE 25 HV PSU Rating
Type
High Voltage DC (HVDC)
High Voltage AC (HVAC)
Similar to the AC PSU that is already supported and released, the HV PSU have an integrated fan in it and therefore will need to match
airflow of the PSU fan to the base chassis airflow. There is only one air direction version and it will intake air from the port side and
exhaust to the non-port side. This PSU is offered to match airflow of the chassis. In summary, following are two HV PSU offerings made
available for SLX 9850-4 .
