Installation and initialization of the system require attention to the normal mechanical, power, and thermal precautions for rack-mounted equipment.
The rack mounting holes conform to the EIA-310 standard for 19-inch racks. Take precautions to guarantee proper ventilation in order to maintain good airflow at ambient temperature.
Unless otherwise specified, NVIDIA products are designed to work in an environmentally controlled data center with low levels of gaseous and dust (particulate) contamination.
The operation environment should meet severity level G1 as per ISA 71.04 for gaseous contamination and ISO 14644-1 class 8 for cleanliness level.
The installation procedure for the system involves the following phases:
|
Step |
Procedure |
See |
|
1 |
Follow the safety warnings |
|
|
2 |
Install a 100A DC disconnect switch |
|
|
3 |
Pay attention to the air flow consideration within the system and rack |
|
|
4 |
Make sure that none of the package contents is missing or damaged |
|
|
5 |
Mount the system into a rack enclosure |
|
|
6 |
Power on the system |
|
|
7 |
Perform system bring-up |
|
|
8 |
[Optional] FRU replacements |
Prior to the installation, please review the Safety Warnings. Note that some warnings may not apply to all models.
Before installing the switch system, make sure a DC disconnect switch is available and can be connected to the switch externally via an over-current DC circuit breaker of up to 100A.
The optimal operating voltage range of the switch system is between 48VDC to 60VDC.
The DC disconnect switch must be provided by the customer.
NVIDIA systems are offered with two air flow patterns:
the images are provided for illustration purposes only. The design may slightly vary in different systems

|
All servers and systems in the same rack should be planned with the same airflow direction.
All FRU components need to have the same air flow direction. A mismatch in the air flow will affect the heat dissipation.
The table below provides an air flow color legend and respective OPN designation.

Direction |
Description and OPN Designation |
|
Connector side inlet to power side outlet. Red latches are placed on the power inlet side. OPN designation is “-R”. |

Power side inlet to connector side outlet. Blue latches are placed on the power inlet side. OPN designation is “-F”. |
Before installing your new system, unpack it and check against the parts list below that all the parts have been sent. Check the parts for visible damage that may have occurred during shipping.
The package content is as follows:
1 – System
1 – Rail kit
1 – Power cable for each power supply unit – Type C13-C14
1 – Harness: HAR000028 – Harness RS232 2M cable – DB9 to RJ-45
1 – Cable retainer for each power supply unit
If anything is damaged or missing, contact your sales representative at enterprisesupport@nvidia.com.
By default, the systems are sold with fixed rail-kits. Telescopic Rail-kits are available for some systems, and should be purchased separately. For installation instructions, refer to the relevant links in the following table:
