Optics
The transceiver goes in the uplink cage. Match it to the fibre: SR for multimode in the building, LR for single-mode.

Matched to its specifications
- Cat 6 patch leads. One short lead per port: 24 for this switch. Gigabit ports run fine on Cat 6. 0.5 m reaches a panel in the next U.
- 24-port patch panel. A 24-port Cat 6 panel gives every switch port a permanent home for the building cabling.
- Cable manager. A 1U manager under the switch holds the slack of 24 leads so the ports stay readable.
- Hook-and-loop ties. Hook-and-loop ties dress the bundles in the manager and on the tray without biting the cable the way a nylon tie does.
- Blank panel. Blank panels close the empty U around the switch so cold air goes through it, not around it.
Project guide
A rack keeps the office online: building cables land once, and a short patch lead is all it takes to move a port. The switch, the fibre and the cabinet sit together so the floor can grow without a mess of new cable.
What each part does21 parts
Patch panel
The panel is the permanent home of the building cabling. A 24-port panel matches a 24-port switch. Use Cat6A shielded panels when the runs are Cat6A or the path shares a tray with power; Cat6 unshielded is enough for a typical office floor under 10 gigabit and away from electrical noise. Blank modular panels let you mix keystones. Loaded panels are faster if every port is the same category.
Brush panel
A brush strip sits directly under the patch panel because that is where the patch cords leave the switch and need to pass to the side of the rack without a hole you can see a hand through. The bristles close around the cords, so the front of the rack stays covered and the cords can still move when you repatch.
Switch
Put the switch in the next U under the brush panel so every patch cord can be 0.5 m or shorter. Add up the PoE each access point and camera will draw, then pick a switch whose PoE budget exceeds that sum by about a third. A 24-port PoE switch feeding eight access points is a different product from a 24-port switch that only links PCs.
Cable manager
A horizontal manager with fingers or rings holds the slack of those short patch cords so the switch ports stay visible. One manager between the panel and the switch, or directly under the switch, is enough for 24 ports. Vertical managers belong in a wider cabinet, not in a 600 mm wall box.
Keystone jacks
Keystones are the jacks that snap into a modular panel or a wall plate. Match them to the cable: Cat6A shielded keystones on Cat6A shielded cable, Cat6 unshielded on Cat6. Mixing an unshielded jack onto a shielded cable drops the shield at the one place it has to continue. Tool-free jacks are slower to go wrong on a ladder.
Patch cords
Patch cords are the only cables you should see from the front. Buy the length you measured: 0.5 m from panel to switch, 1 m when the manager eats some of the run. A Cat6A cord on a Cat6A channel keeps the rating; a Cat6 cord is the weak link if you do the opposite. Snagless boots matter once the rack is full.
Cable tray
The overhead tray carries every building run from the floor to the top of the rack. A wire-mesh or ladder tray keeps data cable off the ceiling grid and apart from power, and you can add a run later without lifting a tile. Size it at about half full so there is room to grow.
Installation cable
Solid-core installation cable is what runs on the tray from each desk socket to the patch panel. Buy it by the 305 m box in the same category as the panel and keystones: Cat 6A for multigigabit and 10G, Cat 6 for a gigabit floor. Stranded patch cord is for the short leads only.
PDU
The PDU feeds the switch, a small router and any modem from one rack circuit. A basic 1U PDU is right for a comms cabinet. Metered and switched PDUs earn their place when the rack is remote and you need to see load or power-cycle a hung switch. Keep the PDU at the bottom or the rear, away from the copper you are terminating.
Shelf
A fixed cantilever shelf holds the one or two devices that have no ears: a firewall appliance, an ONT, a small UPS that is not rack-mount. Check the depth. A 250 mm shelf in a 450 mm wall cabinet leaves room for the plug behind it; a deep shelf in a shallow cabinet will not close.
Wall cabinet
Count the U you just listed, then add two. A patch panel, brush, switch, manager, shelf and PDU is already 6U before spare space, so a 9U or 12U wall cabinet is the usual small office. Depth decides it: 450 mm fits a patch panel and a short switch; 600 mm is the minimum once a PoE switch is involved. Choose a cabinet with room for the cabling and equipment you plan to add.
Floor cabinet
A floor cabinet is the step up when the patch field, the switch and a UPS no longer fit a wall box. Look for 600 or 800 mm of depth and a glass or mesh door so the link lights stay readable.
Router
The router or gateway sits on the shelf or on the bottom of the cabinet, separate from the patch field. It is the device the switch uplinks to. A firewall appliance with no rack ears uses the shelf; a rack-mount router takes 1U of its own.
UPS
A small rack UPS keeps the switch and the router up for a clean shutdown when the cabinet circuit drops. It is heavier than the patch panel, so it belongs at the bottom of the cabinet.
Velcro cable ties
Hook-and-loop ties dress the cords inside the manager without the permanent bite of a nylon zip tie. They are in the panel when you pull it out, available alongside the equipment. Add them only if you want them in the cart.
Punch down tool
A punch-down tool seats each conductor of the horizontal cable into the keystone or the panel IDC. It is a tool, not something mounted in the rack, so it only appears here when the catalogue actually has one.
SFP+
An SFP+ transceiver is the optic that sits in the switch's uplink cage. Match the fibre you pulled: multimode SR for a short run inside the building, single-mode LR when the run leaves the floor. The switch is the chassis; the optic is a part you add when that uplink needs it.
DAC
A direct-attach copper cable links the switch to a router in the same cabinet, where a fibre jumper would be wasted. Check the connector: SFP+ at both ends for a 10 gigabit uplink. It is available alongside the equipment.
Fibre jumpers
Fibre jumpers connect the patch field to the next device. Match the connector and the polish to the transceiver. They stay optional: opening the panel does not put every jumper in the cart.
Stacking cable
A stacking cable joins two switches of the same family so they behave as one. It only belongs in the build when you are actually stacking, and only when the catalogue has the cable for that switch.
Switch power supply
A spare or redundant power supply is for a switch that has a second bay. It stays out of the cart until you choose it.

Questions
Why use short patch leads?
Building cable stays on the back of the patch panel. A short lead from the front of that panel to the switch is the only piece you change when a desk moves. Open the patch panel or the switch on this page to see the jacks, the ties and the optics that belong with them.
Why does a brush panel sit under the patch panel?
The patch cords leave the front of the panel and have to reach the switch without sticking through an open slot. A brush strip in the U underneath lets the cords pass and closes around them, so the cabinet face stays covered and you can still pull a cord through when a port moves.
Should the keystones be Cat6 or Cat6A?
Match the cable you pulled. Cat6A shielded cable needs Cat6A shielded keystones, or the channel is no longer Cat6A and the shield stops at the jack. Cat6 unshielded keystones are the right pair for Cat6 unshielded runs. The patch panel has to be the same category as the jacks that fill it.
How much PoE budget does the switch need?
Add the maximum draw of every powered device on the switch, not the typical draw. An access point that can take 25 W counts as 25 W even if it usually sits lower. Leave about a third spare so a cold start, when every device boots together, does not trip the budget and drop the last ports.
What depth of cabinet fits a PoE switch?
A patch panel is shallow. A PoE switch usually needs 300 to 400 mm, and the plugs behind it need more. A 450 mm wall cabinet is tight once the switch is in; 600 mm is the depth that still closes with the cables dressed. Measure the switch, then add 100 mm.
