Installing a storage tray - NeXtScale nx360 M4 compute node

Use this information to install a storage tray in a NeXtScale nx360 M4 compute node.

Before you install the compute node in a chassis, read Safety and Installation guidelines.

To install the storage tray to compute node, complete the following steps:

Hard disk drive fillers must be installed by referring the following table when the hard disk drives are not fully populated.

Table 1. Hard disk drive configuration for storage tray.

Internal storage node	HDD quantity	7	6	5	4	3	2	1	0
	Drive bay 0	HDD	HDD	HDD	HDD	HDD	HDD	HDD	Filler
	Drive bay 1	HDD	HDD	HDD	HDD	HDD	HDD	Filler	Filler
	Drive bay 2	HDD	HDD	HDD	HDD	HDD	Filler	Filler	Filler
	Drive bay 3	HDD	HDD	HDD	HDD	Filler	Filler	Filler	Filler
	Drive bay 4	HDD	HDD	HDD	Blank	Blank	Blank	Blank	Blank
	Drive bay 5	HDD	HDD	Blank	Blank	Blank	Blank	Blank	Blank
	Drive bay 6	HDD	Blank	Blank	Blank	Blank	Blank	Blank	Blank

If a hard disk drive fails, it is recommended to keep the failed hard disk drive in the storage tray until installing a new hard disk drive or a filler.

Carefully lay the storage tray on a flat, static-protective surface, orienting the storage tray with the release latch near your right hand side.
Connect the configuration cable, the hardware RAID (signal) cable, and the mini-SAS cable to the storage tray.
Install the easy-swap hard disk drive #6 (see Installing a 3.5-inch hard disk drive).
Orient the storage tray so that the posts on the inside of the storage tray slide into the slots on the compute node.
Note: Before you install the storage tray, make sure that the air baffles and all components are installed and seated correctly and that you have not left loose tools or parts inside the compute node.
