• Power consumption 45 W typical

Power Block

The NSR AC devices have a single or dual power supply, depending on the selected model. The dual AC model provides power redundancy for the appliance. The power sockets are designed for industry-standard C13 cables. It is recommended that the power cables be affixed to an appropriate cable management solution, observing the minimum bending radius for the cables.

IMPORTANT: The cable-specific requirements, like bending radius, must be confirmed with the cable vendor.

Grounding

The NSR AC devices must be appropriately electrically grounded. The NSR appliance offers two methods for this:

• On the left-hand side of the appliance is the ground/earth screw. AC units use this option.

• DC units should be grounded using the appropriate ground pins from both terminal blocks.

Installation Guide

NSR devices are designed to be installed into a data center rack. Modern racks offer various cable management options, and customers can implement their specific cable management guidelines. This guideline outlines an installation method using traditional cable management options, which use lacing bars to guide and affix cables. One lacing bar is recommended, either mounted directly above or below the NSR appliance.

Guidelines

Customers may decide to implement their guidelines, but the following general requirements should be observed for the installation of NSR AC:

• Observe the minimum bending radius for the used power cables for non-motion. For example, a fire-resistant 4m cable with a 6.6 mm diameter might have a typical non-moving minimum bending radius of 40mm.

• Affix the AC power cables to a lacing bar or other appropriate mounting facility provided by the rack.

• AC power cables should be guided to the left side and console cables to the right, separating power and other passive cabling clearly.

Rackmount

1. Attach ear mounts from the NSR accessory box using the Phillips #2 screwdriver and provided screws to the unit.

2. Install the cage nuts

3. Install the NSR unit with the power outlets and console connection facing the installer.

4. Install the lacing bar below the NSR.

Connect NSR to AC Power Source

1. Make sure both power switches on NSR are turned OFF. The off position is indicated by the flipped power switch to the left.

2. Ensure the power outlet to which the units will be connected is turned off.

3. Starting with Power Supply A:

   • Plug the C13 power cable into the appropriate power socket on the NSR.

   • Run the power cable to the lacing bar, then to the left side of the rack.

   • WARNING: Ensure the cable is not bent too tightly and follows the minimum bending radius.

   • Affix the cable to the lacing bar with Velcro to prevent it from being moved by mistake or accident.

4. Repeat steps 3-6 for Power Supply B for DAC units.

5. Connect the power cables to the power source, starting with Power Supply A, followed by Power Supply B.

6. Connect any other cables to the appliance, such as device console cables, network cables, and a device console cable.

7. Turn on both power sources.

8. The unit will power on and boot up.

9. Connect the console cable to a laptop or other appropriate device.

10. Open a terminal program and connect to the serial console port using 115200,8,N,1,N.

11. The console connection will display the boot process until the unit is fully booted and a login prompt is displayed.

12. The unit is now ready to be configured; see the User Manual for more details at https://docs.zpesystems.com.
    

    Note

    • On the Nodegrid Net Services Router with PoE support, the second power supply specifically powers the PoE feature and does not provide power outage redundancy.

    • When all power supplies are appropriately connected to a power source, power can be turned on.
