I/O punching
The LAN cable is punched onto an information outlet (keystone jack) at the wall or floor box. That I/O is the data point you plug a patch cord into at the desk, printer, camera or WiFi access point.
LAN punching on site, near you
This page is for termination work: punching the cable you already have, or a short extra run, so the point actually works. Full office cabling, racks and switches are quoted separately as LAN and structured cabling.
A common call is a desk, cabin, camera or access point where the LAN cable is in the wall but the I/O was never punched, the RJ45 head is broken, the faceplate is loose, or the rack end was never punched on the patch panel. TRULINK comes to the address, terminates the link, labels it, and tests it before leaving.
Jacks, RJ45 plugs, faceplates, gang boxes, patch panels and extra cable are quoted if they are not already on site. Labour is quoted after we see the points and the rack.
What we punch
RJ45 connector punching
An RJ45 (8P8C) plug is crimped on Cat5e or Cat6 cable for a patch cord, camera tail or short fly lead. Pair order is kept consistent and the cord is checked with a tester.
Faceplate and gang box fitting
The gang box is fixed in the wall or on the surface, then the modular faceplate is fitted so the I/O sits flush and the cable is not hanging from a loose jack.
Patch panel punching
The rack end of each run is punched onto the patch panel, dressed and labelled, then patched to the switch. That is how a structured LAN stays tidy when you add or move points later.
How to punch a LAN cable
A punched link has the same wiring scheme at both ends, pairs that stay twisted close to the contacts, and a tester pass before handover. TRULINK does this on site. The steps below are what the technician follows.
How to punch an I/O (keystone jack)
I/O punching terminates the wall end of a Cat5e or Cat6 run onto a keystone jack. The jack then clicks into the faceplate.
- Leave slack in the gang box. Strip about 25 mm of jacket. Do not nick the pairs.
- Pick T568A or T568B to match the other end. The A and B colour rows are printed on most Cat6 jacks.
- Untwist each pair only as far as the IDC slot. Seat every conductor in its colour.
- Punch each wire into the IDC so the tool cuts the excess. Fit the dust cap if the jack has one.
- Snap the jack into the faceplate from the rear, then test the link.
How to punch an RJ45 connector
RJ45 punching (crimping) puts an 8P8C plug on a patch cord, camera tail or fly lead. Pass-through or standard plugs both need a full crimp so the contacts bite the copper.
- Strip about 25 mm of jacket. Fan the pairs into T568A or T568B order.
- Flatten the eight wires, then trim them even so the jacket will sit inside the plug strain relief.
- Slide the wires in until they reach the front of the plug. Check the colour order through the plastic.
- Crimp fully. The pins should pierce the insulation and the bar should clamp the jacket.
- Test continuity and pair order before the cord is used.
How to fit a faceplate and gang box
The gang box holds the cable slack. The faceplate holds one or two I/O jacks so the point sits flush on the wall.
- Fix a concealed or surface gang box at the desk, camera or AP location.
- Feed the LAN cable in with enough slack to punch the jack without pulling on the run.
- Punch the I/O, then clip each jack into a single-gang or dual-gang plate.
- Screw the plate to the box so the jacks are not hanging on the cable.
A dual plate is used when two data points share one box. The plate type must match the keystone size.
Faceplate types
Modular plates take the same keystone I/O used at the punch-down. One port for a single desk drop, two ports when a PC and a phone, printer or camera share the box. Shuttered plates keep dust out of unused jacks.
How to punch a patch panel
The rack end of each horizontal run is punched on the patch panel. Patch cords then go from the panel to the switch, so ports stay labelled and spare.
- Dress cables to the rear of the panel. Keep the same port number as the wall I/O.
- Strip a short jacket length. Seat pairs on the panel IDC in the same T568A or T568B scheme as the I/O.
- Punch down each conductor. Trim and add strain relief or Velcro so the bundle does not pull the IDC.
- Label the panel port. Patch to the switch. Test wall jack to panel port, then confirm the switch port comes up if the switch is live.
T568A and T568B wire order
Both ends of one link must use the same scheme. Mixing A and B on a single run is a straight-through vs crossover mistake and the tester fails. T568B is the usual choice in Gurgaon offices when the site has no existing standard.
| Pin | T568A | T568B |
|---|---|---|
| 1 | White/Green | White/Orange |
| 2 | Green | Orange |
| 3 | White/Orange | White/Green |
| 4 | Blue | Blue |
| 5 | White/Blue | White/Blue |
| 6 | Orange | Green |
| 7 | White/Brown | White/Brown |
| 8 | Brown | Brown |
When this service helps
Cable in the wall, no working point
The installer left a Cat6 tail in the box but never punched the I/O, so there is nothing to plug a laptop or camera into.
Broken RJ45 or intermittent link
A crushed plug, a split pair or a poorly crimped head drops speed or drops the link. The connector is re-punched and tested.
Loose faceplate or missing gang box
The plate is hanging, the box was never fitted, or a dual-gang plate is needed for two data points at the same desk.
Rack cables not on the panel
Runs reach the rack but sit as a bundle of untidied tails. Punching them on the patch panel lets the switch ports stay labelled and spare.
What to share before the visit
Call or WhatsApp +91 96258 62001 with:
- The site address in Gurgaon, Gurugram or nearby Delhi NCR
- Whether you need I/O punching, RJ45 crimping, a faceplate and gang box, a patch panel, or a mix
- How many points, and whether the cable is already in the wall or rack
- Whether you already have jacks, plugs, plates or a panel on site
Access to the wall boxes and the rack or switch location is required so the technician can punch both ends of each link.

Common questions
Do you do LAN cable punching near me in Gurgaon?
Yes. TRULINK punches I/O points, RJ45 connectors, faceplates, gang boxes and patch panels at homes, shops and offices in Gurgaon (Gurugram) and nearby Delhi NCR. Share the address on a call or WhatsApp so the visit can be booked.
How do you punch an I/O (keystone jack)?
Strip a short length of jacket, keep the pairs twisted, seat each wire in the T568A or T568B colour slots on the jack, punch them into the IDC, trim the excess, then clip the jack into the faceplate. Both ends of the link must use the same scheme.
How do you punch or crimp an RJ45 connector?
Arrange the eight wires in T568A or T568B order, trim them even, slide them into the RJ45 plug so the jacket sits in the strain relief, then crimp until the contacts bite through the insulation. Test the cord before it is used.
What is I/O punching?
I/O punching is terminating a LAN cable onto an information outlet (keystone jack) at the wall or floor box. The eight wires are seated in the jack so a patch cord can plug in at the desk, printer, camera or access point.
Do you crimp RJ45 connectors on site?
Yes. We punch and crimp RJ45 (8P8C) plugs on Cat5e or Cat6 cable for patch cords, camera tails and short fly leads, then check the pair order with a cable tester.
Can you fit a faceplate and gang box?
Yes. We fit the gang box (concealed or surface) and the modular faceplate that holds the I/O. Single-gang and dual-gang plates are used to match the point count at that location.
Do you punch a patch panel in an existing rack?
Yes. Horizontal cables are punched onto the patch panel at the rack, dressed and labelled, then patched to the switch. If the rack or panel is missing, that material is quoted before work starts.
Do you follow T568A or T568B?
We match the wiring scheme already used on the site so new points stay compatible. If the site has no existing standard, T568B is the usual choice in Gurgaon offices. Both ends of a link use the same scheme.
What tools are used to punch a LAN cable?
A punch-down tool (110) for I/O and patch panels, an RJ45 crimp tool for plugs, a cable stripper, and a pair tester. TRULINK brings these on the visit.
Is the visit charge separate from punching labour?
Yes. On-site visits are charged by distance from the TRULINK shop in Gurgaon: ₹399 up to 7 km, ₹499 up to 10 km and ₹999 up to 15 km. Jacks, RJ45 plugs, faceplates, gang boxes, patch panels, cable and punching labour are quoted separately.
Can you also pull new LAN cable?
Yes. Short extra runs are often done in the same visit. A new office layout, a rack install or a full floor of points is quoted as LAN and structured cabling after a survey.
