Installation Instructions

Secure Racking

If Secure Racked units are installed in a closed or multi-unit rack assembly, they may

require further evaluation by Certification Agencies. The following items must be

considered.

1. The ambient within the rack may be greater than room ambient. Installation

should be such that the amount of air flow required for safe operation is not

compromised. The maximum temperature for the equipment in this environment is

60°C. Consideration should be given to the maximum rated ambient.

2. Installation should be such that a hazardous stability condition is not achieved due

to uneven loading.

Input Supply

Check nameplate ratings to assure there is no overloading of supply circuits that could

have an effect on overcurrent protection and supply wiring.

Grounding

Reliable earthing of this equipment must be maintained. Particular attention should

be given to supply connections when connecting to power strips, rather than direct

connections to the branch circuit.

No Serviceable Parts Inside; Authorized Service Personnel Only

Do not attempt to repair or service this device yourself. Internal components must be

serviced by authorized personnel only.

• ShockHazard-DoNotEnter

• LithiumBattery

CAUTION:Dangerofexplosionifbatteryisincorrectlyreplaced.Replace

onlywithsameorequivalenttyperecommendedbythemanufacturer.

Discardusedbatteriesaccordingtothemanufacturer'sinstructions.

Disconnect Power

If any of the following events are noted, immediately disconnect the unit from the outlet

and contact qualified service personnel:

1. If the power cord becomes frayed or damaged.

2. If liquid has been spilled into the device or if the device has been exposed to rain

or water.

Warnings and Cautions

Two Power Supply Cables

Note that some NBB series units feature two separate power inlets and a separate

power supply cable for each power inlet. Make certain to disconnect all power supply

cables from their power source before attempting to service or remove the unit.

15 Amp Starter Cable(s)

If the NBB unit includes a detached, 125 VAC, 15 Amp “Starter” Cable(s,) this allows

you to connect the NBB to power for bench testing and initial start up is adequate for

applications that only require 15 Amps. For 20-Amp power switching applications,

please refer to the WTI Power Cable guide, or use appropriate 20-Amp cables.

Units with Attached Power Supply Cable(s)

For units with fixed power cords, the socket-outlet shall be installed near the equipment

and shall be easily accessible.

1. Introduction

This Hardware Guide covers set-up and installation for our NBB Series Network Power

Switches. NBB Series units are designed to simplify the process of remotely managing

vital network elements located at distant network equipment sites and off-site facilities

by providing secure remote access to power switching and reboot functions at the

remote network equipment site.

Note: For instructions regarding configuration and operation of the NBB Series

Device, please refer to the WTI Firmware Guide.

Model Numbers Covered

This User’s Guide discusses all WTI NBB Series products. Throughout this Hardware

Guide, all of these units are referred to as the "NBB."
