Getting started

For a new customer and the person on site who receives the sensors. It covers unpacking, powering on, placement, the decisions to make before go-live and signing in to the portal.

The sensors

Model	Connects by	What it is for
ModelB	Wired Ethernet or Wi-Fi	Tests the service path from the office: application response, DNS, the network path and Wi-Fi link and signal
ModelC	As ModelB, plus a Wi-Fi 7 adapter	As ModelB, for sites with Wi-Fi 7 access points
ModelA	Wi-Fi only (Wi-Fi 6, 2.4 and 5 GHz)	A small probe that measures Wi-Fi where people sit

Each sensor carries a Device ID on a label at the back. Your administrator uses it to assign the sensor to a site and floor, so keep a note of which Device ID goes where.

What's in the box

ModelB and ModelC

A CNA ModelB sensor: a black finned enclosure with an L-shaped bracket screwed to one end and the white power cable held against it by a cable clip. — A ModelB sensor with a bracket and cable clip fitted.

The sensor
A power supply with a USB-C cable (output 5.1 V, 3 A)
Two L-shaped brackets
An R-type cable clip
Two hex socket button-head screws, 4 mm and 8 mm long
A 2 mm hex key
Two wood screws
A small piece of self-amalgamating tape, for the cable grip

[PLACEHOLDER: confirm whether the ModelC kit differs, and how its Wi-Fi 7 adapter is supplied and fitted]

The white UK-plug power supply with its coiled USB-C cable. — Power supply, USB-C.

A black L-shaped mounting bracket with a screw hole in each arm. — L-shaped bracket (two supplied).

A black R-type cable clip with a single screw hole. — R-type cable clip.

Mounting and powering on

Fit the brackets. Screw the two L-shaped brackets to the sensor with the hex key. They let you fix the sensor under a desk or table, or on a wall or panel, using the wood screws.
Connect the network (ModelB and ModelC on a wired desk). Plug the sensor into a live port on the user network.
Connect the power. Plug the USB-C cable into the sensor and the power supply into the mains.
Secure the cable. Hold the power cable against the sensor with the R-type cable clip, wrapping a little self-amalgamating tape round the cable for grip, so it can't be pulled out by accident. If you fit the cable clip together with a bracket, use the longer 8 mm screw.
Record the position. Note the Device ID and the desk on your floor plan. Your administrator needs it for the floor map.

Status lights

The back of a CNA sensor: the CNA Device ID label, and a green and a red status light at its bottom right. — The status lights sit under the Device ID label, at the bottom right.

Light	When it is on
Red	At start-up, and if a critical system error occurs
Green	At start-up, and during processor activity

If the red light comes on after start-up, the sensor has hit a critical error: contact support with its Device ID.

Where to place sensors

The aim is for sensors to experience the network the way your staff do: at their desks, spread across the floor, including the worst spots.

ModelB on a wired desk. Choose a desk with a live port on the user network, mid-row or mid-room, and mount the sensor under it.
ModelA where people sit. At desk height, on every other desk, staggered across back-to-back rows. Not inside metal pedestals or cabinets.
Cover the edges, not just the centre. Include row ends, room corners and the desks furthest from access points.
Don't cluster under access points. A sensor directly beneath one reports best-case Wi-Fi. Spread sensors across each area.
Record every position. Mark each sensor and its desk on the floor plan when you install it. The floor maps depend on it.
Keep each group in one zone. Keep the sensors that work together within one room or desk row, so results map cleanly to a place.

How many sensors a floor needs depends on its layout: see Sensors.

Five decisions before go-live

Your administrator sets these up in the portal, normally in this order. The first three place the sensors; the last two decide what they test and who hears about problems. Gather the information early.

Step	What you decide	What to have ready
1. Sites	Each office being monitored	A short site code, the address and the public IP address of each internet or WAN circuit (up to two per site)
2. Sensors	Which sensor goes where, and how it connects	Each Device ID with its site, floor and desk; the Wi-Fi networks and security type, or the wired network details
3. Wireless maps	Where each sensor sits on each floor	A floor plan image for each floor, ideally showing desks, wired ports and access points
4. Applications	What the sensors test	The applications your people can't work without, with a URL for each
5. Alerts	Who is told, and when	The people or mailboxes for each alert, and what "too slow" means for each application and site

Step by step: IoT administration.

Signing in to the portal

[PLACEHOLDER: portal sign-in address, provided at onboarding]

Single sign-on. If your organisation signs in through its identity provider, such as Okta or Entra ID, use your usual work account. Your password is managed there, not in CNA.
CNA account. Otherwise, sign in with the user name and password you were given, and change the password from your profile.

If your organisation has restricted the portal to its own network or VPN, sign in from there.
