Matched to its specifications

  • M.2 NVMe SSD. The drive is an M.2 2280 NVMe stick. A larger one is the cheapest upgrade a slow laptop can get.
  • Thunderbolt dock. One Thunderbolt cable to a DIGITUS dock brings screens, network, keyboard and charging to the desk.
  • USB-C hub. A pocket USB-C hub covers the meeting room and the train: HDMI, USB-A and a card reader.
  • Network adapter. This laptop has no network socket. A USB-C to Gigabit Ethernet adapter puts it on the wired network.
  • Network lead. A Cat 6 lead from the desk socket to the dock or laptop. 2 m reaches a floor box under the desk.
  • HDMI cable. A high-speed HDMI cable for the second screen.
  • Laptop stand. A stand lifts the screen to eye level beside the monitor.
  • Monitor arm. A clamp-on arm frees the desk under the screen and sets it at the laptop's height.
  • Under-desk cable tray. A tray under the desktop holds the power strip and dock leads off the floor.

Licences and support

Project guide

A small office runs from one access point and a switch in the cupboard. Each desk then wants a screen, a chair and a short lead, so people can sit down and work. Check PoE power, uplinks and model compatibility before ordering.

What each part does29 parts

Lighting

The long linear LEDs on the ceiling are the lights in this room. Match the colour temperature across the floor so the monitors and the faces are not lit by two different whites. The dot sits on a fitting, not on anyone under it.

Desk

The foreground surface is the desk. A sit-stand desk, preferably an electric Equip desk, is the one to specify when people are at it all day. Cable clips are not a desk, and they are excluded from this search.

Chair

An ergonomic office chair, preferably Equip, belongs at each of these desks. Gaming chairs are a different product and are not what this slot looks for.

Task chair

The chair at the near desk. Choose an ergonomic office chair, preferably Equip, and skip gaming chairs. The base and the back are what you are buying, not a costume.

Side chair

The empty chairs along the row are the same spec as the one at the first desk. One model across the floor is easier to replace than a mix.

Return desk

The desks further down the row. A sit-stand desk, preferably electric and from Equip, is the one to specify when people are at it all day.

Laptop

A laptop on the desk is the machine people carry between the office and a meeting. Check the screen size and the ports before you pair it with a dock.

Windows

Business laptops usually ship with Windows 11 Pro. Buy a licence only for a machine sold without one, or to move from Home to Pro for domain join and BitLocker.

Office apps

Microsoft 365 puts Word, Excel, Outlook and Teams on the laptop and keeps mail and files in one account per person. A one-off Office licence suits a machine that never needs the cloud side.

Laptop memory

Laptops take SO-DIMM modules, not desktop DIMMs. Check that the model has a free slot and whether it takes DDR4 or DDR5 before adding memory; many thin models have it soldered.

Laptop SSD

Most current laptops take one M.2 2280 NVMe drive. A larger SSD is the simplest upgrade; check the length the model accepts and clone the old drive before swapping.

Laptop bag

A bag sized to the screen keeps the laptop from sliding. Match the inch size, and allow room for the charger and a mouse.

Printer

A shared printer at the end of the desk run covers the floor. Put it where the cable and the paper path are clear, not in a cupboard that overheats it.

Desk divider

A privacy screen between neighbouring desks keeps the screens from facing the aisle. Match the height to a seated person so it blocks the glance, not the light.

Access point

Ceiling-mount the access point near the middle of the room, not in the rack and not behind a metal ceiling tile. One Wi-Fi 6 or Wi-Fi 7 access point covers a small office; a second is for a thick wall or a second floor, not for a stronger signal in the same room. Power it from the PoE switch. A spare port on that switch is the cleanest injector you can buy.

PoE switch

The switch lives in the cabinet from the networking setup, or on a shelf in the cupboard, and it powers the access point and the desk phones. An 8-port PoE switch with a 60 to 120 W budget covers one access point and a handful of phones. Add the phone and access-point wattages before you pick the budget. Data-only ports can feed the docks; they do not need PoE.

Network gateway

The gateway connects the office network to its internet service. Choose it with the access point and switch so the network can be managed together. Check the WAN connection, capacity and required licences for the selected model.

Docking station

One USB-C dock per desk replaces the tangle of display, network and power leads. Check the laptop's USB-C port actually carries display and power; a charge-only port will not drive the monitor. A dock with its own power supply is more reliable than one that tries to run a 27-inch screen from the laptop. The network port on the dock is what you patch to the wall socket.

Monitor

A 24-inch 1080p screen is the ordinary desk. A 27-inch is the step up when someone works in two windows all day. Match the dock's output: HDMI or DisplayPort, and a USB-C monitor only if the dock or the laptop can feed it. Two screens need a dock with two video outputs, not a splitter.

Webcam

A webcam on the meeting-room screen, or a speakerphone in the middle of the table, is what the people at the far end actually see and hear. A laptop at the end of the table points at the ceiling. For a huddle room, a 1080p webcam with a wide enough field to take in three people is the useful minimum. Put it at eye height, on the screen, not on the table.

Desk phone

A PoE desk phone needs one cable to the wall socket and nothing else. Pick a phone that matches the PBX you already run; a SIP phone will not register to a system that only speaks a vendor's own protocol. One phone per person who takes calls, plus one in the meeting room if people still dial in rather than join on the laptop.

Cabling

The desk lead is a patch cord from the wall socket to the dock or the phone, usually 2 or 3 m so it can be dressed along the desk and still reach. The run inside the wall is solid cable terminated on a keystone, not a long patch cord buried in the plaster. Label both ends with the panel port. A floor box or a cable tray beats a cord across the walkway.

Wall socket

A surface or flush socket at desk height, with one or two keystones, is the end of the horizontal cable. Two outlets per desk cover a phone and a dock without a desktop switch. The socket has to face the desk, not sit behind a drawer unit. Use the same category of keystone as the cable in the wall.

Motion sensor

A motion or occupancy sensor can drop the linear lights when the floor is empty. It is available alongside the equipment. A headlamp is not a sensor, and the search excludes it.

Keyboard

One keyboard per desk, matched to the dock.

Mouse

A mouse next to the keyboard, not a mouse mat and not a laptop trackpad.

Headset

A wired or wireless headset for the people who take calls at these desks.

Meeting bar

A video bar belongs on the meeting-room screen, at the far end of a room like this, not on a desk in the open floor.

Speakerphone

A speakerphone in the middle of a meeting table is what the far end hears.

A small meeting room off the same switch: an access point if the wall is thick, a screen with a webcam, and a dock so a laptop joins with one cable.

Questions

Where should the access point go?

On the ceiling, towards the middle of the space it has to cover, with a clear view of the room. A metal ceiling tile, a duct, or a rack in a cupboard will shadow an access point. One is enough for a small open office; a second is for another room or another floor.

How many PoE watts do phones and an access point need?

Read the maximum draw, not the idle draw. A Wi-Fi 6 access point is often 15 to 25 W, and a desk phone is often under 10 W. Four phones and one access point can sit inside a 60 to 90 W budget, but only if you add the figures from the datasheets of the models you are buying. Leave headroom for a cold start.

What is the difference between the wall socket and the patch cord?

The cable inside the wall is solid-core, terminated on a keystone in the socket, and it stays there. The patch cord is stranded, and it runs from that socket to the dock or the phone, where it gets unplugged. Do not bury a patch cord in the wall, and do not use solid cable as a desk lead. It breaks at the plug.

Will any USB-C dock run the monitor?

Only if the laptop's USB-C port carries video (DisplayPort Alt Mode) and the dock has the output your screen uses. A port that only charges will not drive a monitor through the dock. Two screens need two video outputs on the dock. A splitter on one output mirrors the same picture.
