Replace Dc Power Supply Units In H615C And H610S Nodes - NetApp HCI Manual

Replace DC power supply units in H615C and H610S nodes

H615C and H610S nodes support two –48 V to –60 V DC power supply units. These
units are available as optional add-ons when you order H615C or H610S nodes. You can
use the these instructions to remove the AC power supply units in the chassis and
replace them with DC power supply units, or to replace a faulty DC power supply unit with
a new DC power supply unit.
What you'll need
• If you are replacing a faulty DC power supply unit, you have procured a replacement DC power supply unit.
• If you are swapping out the AC power supply units in your chassis with DC units, you have taken into
consideration the downtime for the procedure.
• You have an electrostatic discharge (ESD) wristband, or you have taken other antistatic precautions.
• You have ensured that the power supply requirements are met:
◦ Supply voltage: –(48-60) V DC
◦ Current consumption: 37A (maximum)
◦ Breaker requirements: 40A breaker
• You have ensured that the materials in your environment adhere to the RoHS specifications.
• You have ensured that the cable requirements are met:
◦ One UL 10 AWG, 2 m maximum (stranded) black cable [–(48-60) V DC]
◦ One UL 10 AWG, 2 m maximum (stranded) red cable [V DC return]
◦ One UL 10 AWG, 2 m maximum green/yellow cable, green with a yellow stripe, stranded wire (safety
ground)
About this task
The procedure applies to the following node models:
• One rack unit (1U) H615C compute chassis
• 1U H610S storage chassis
In the case of H615C and H610S, the terms "node" and "chassis" are used

interchangeably because node and chassis are not separate components, unlike in the
case of the 2U, four-node chassis.

You cannot mix AC and DC power supply units in your installation.
Steps
1. Turn off the power supply units and unplug the power cords. If you are replacing a faulty DC power supply
unit, turn off the power source and remove all the cables inserted into the blue connector.
2. Lift the cam handle, and press the blue latch to slide out the power supply unit.
