Summary
Restores or enables wired network connectivity by patching a labeled wall jack to an available switch port in the correct
Communications Equipment Room (CER), then documenting the patch cord and setting the intended network assignment in IRIS.
Symptoms / Problem Statement
- User reports no network connectivity when plugged into a specific wall jack.
- Newly installed or newly requested wall jack has no active network connection.
- Wall jack is labeled, but the corresponding patch panel port is not patched to a switch port.
- Physical patch exists, but IRIS does not reflect the jack-to-port mapping and/or the correct network assignment.
Applies To
- On-premises wired Ethernet wall jacks that terminate to a patch panel in a CER
- CER patch panels and access switches managed/tracked in IRIS
- IT staff responsible for physical layer patching and IRIS documentation
Environment
- Campus/building wired network infrastructure (wall jack → patch panel → access switch)
- CER containing the patch panel and associated access switch
- IRIS (web): https://iris.techservices.illinois.edu/
Prerequisites
- Physical access to the room (wall jack) and the correct CER (patch panel and switch)
- Wall jack identifier (exact label from the faceplate)
- Patch cable of appropriate type/length for the rack and cable management materials (as needed)
- IRIS access with permissions to view ports and update Patch Cords
- Confirmed desired network assignment for this jack (per request/standard)
Assumptions to review (update to match local standards):
- Wall jack labeling correctly maps to the patch panel port labeling.
- The switch located below/associated with the patch panel is the correct access switch for the jack.
- Desired network refers to the network assignment option available in IRIS (for example, a VLAN/network profile).
Resolution / Steps to Resolve
-
Identify the wall jack in the room.
- Record the jack label exactly as shown on the faceplate.
-
Locate the CER that houses the patch panel for that jack.
- Use building documentation/labeling and confirm you are at the correct rack and patch panel.
-
Identify the patch panel port that corresponds to the wall jack.
- Match the jack label to the patch panel labeling.
-
Identify the switch below that patch panel.
- Confirm the switch identity (label, rack position, or IRIS inventory mapping).
-
Find free ports on the switch using IRIS.
-
Connect a patch cable between the jack (patch panel port) and the selected switch port.
- Patch from the correct patch panel port (for the wall jack) to the chosen free switch port.
- Use proper cable management per local standards.
-
Update IRIS to document the patch and set the network assignment.
- In IRIS, go to Patch Cords.
- Locate the patched switch port.
- Set the desired network.
- Enter the wall jack name/label in the Jack Field.
- Click Overwrite Name.
-
Verify connectivity (recommended).
- Confirm link/activity on the switch port (lights and/or port status in IRIS/tools).
- If possible, test at the wall jack with a known-good device to confirm connectivity on the expected network.
Triage Questions
- What is the exact wall jack label (as printed on the faceplate)?
- Which building and room is the jack located in?
- Which CER serves this room/jack?
- Is there an existing IRIS record for the jack, patch panel port, or switch port?
- What is the desired network assignment for this jack?
- Is this a new activation request or a previously working jack that stopped working?
Troubleshooting Notes / Common Issues
-
Jack label does not match patch panel labeling
- Re-check the wall jack label and confirm you are in the correct CER and at the correct patch panel.
- Check for alternate labeling conventions (panel position vs. printed jack ID).
-
No free ports available on the switch
- Confirm you selected the correct switch in IRIS.
- Escalate per local process for capacity expansion or port cleanup.
-
IRIS shows the port as in-use but it appears physically free
- Confirm switch and port identity before making changes.
- Update IRIS only after verifying the physical state and any dependencies.
-
Patched correctly but no connectivity
- Confirm the desired network is correct in IRIS.
- Try a known-good patch cable.
- Test the endpoint device and wall jack (swap device, use a cable tester if available).
-
Cannot update fields or overwrite fails in IRIS
- Confirm your IRIS permissions.
- Refresh the session and retry after reloading the switch/port record.
Additional Information
Frequently Asked Questions
Q: Where do I enter the wall jack label in IRIS?
A: In IRIS, go to Patch Cords, locate the patched switch port, enter the label in the Jack Field, then click Overwrite Name.
Q: Should I update IRIS before or after patching the cable?
A: Patch first, then update IRIS to match the confirmed physical connection.
Q: What if I don’t know the desired network?
A: Do not guess. Use the request details, local standards for that location, or escalate to the network team for the correct network assignment.
