What This Guide Helps With
This guide helps troubleshoot the GE Healthcare MAC 5 error Plug in the USB or Connect the Device to the Network and Then Continue the Upgrade Progress. This condition may occur during a manual software upgrade when the USB flash drive is removed, the network connection drops, or the device loses access to the upgrade source before the upgrade process is complete.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Confirm the MAC 5 is not being used for patient ECG acquisition.
- If the device is in a clinical area, remove it from patient use until the software upgrade issue is resolved.
- Use another ECG machine if patient testing is needed.
- Expected: No patient testing depends on a device in an incomplete or interrupted upgrade state.
Verify the Reported Error and Behavior
- Confirm the displayed error is exactly: Plug in the USB or Connect the Device to the Network and Then Continue the Upgrade Progress.
- Determine whether the error appeared during manual software upgrade, after the USB flash drive was removed, after the network connection dropped, after switching between USB and network upgrade sources, or during retry or continuation of upgrade progress.
- Expected: The error is clearly linked to interrupted access to the upgrade source.
- Why it matters: This confirms the issue is not a general boot failure or software corruption complaint, but a loss of access to the upgrade media or network path.
Check Whether the Upgrade Was Started from USB
- Ask the user or check the workflow to confirm whether the upgrade was being performed from a USB flash drive.
- If USB upgrade was used, verify the USB drive is still inserted securely into the MAC 5.
- Remove and reinsert the USB flash drive firmly.
- Expected: The device detects the USB drive and allows the upgrade process to continue or restart.
- Why it matters: The error can occur if the USB flash drive was removed before the manual upgrade completed.
Inspect the USB Flash Drive and USB Port
- Check the USB flash drive for obvious physical damage, bent connector, looseness, or contamination.
- Inspect the MAC 5 USB port for damage or poor fit.
- Try a known-good USB flash drive prepared with the correct upgrade files if available.
- Expected: The USB device remains connected and readable without intermittent disconnects.
- Why it matters: A loose or unreliable USB connection can interrupt the upgrade even if the user did not intentionally remove the drive.
Confirm the USB Contains the Upgrade Files
- Verify the USB flash drive contains the required software upgrade image and related files in the expected location.
- Do not move, rename, or delete files during the upgrade attempt.
- Expected: The USB drive contains the valid upgrade files required for the MAC 5 to continue.
- Why it matters: If the device reconnects to USB but cannot find the expected upgrade content, the upgrade may fail again or display a different upgrade error.
Check Whether the Upgrade Was Started from the Network
- If the upgrade was being performed from a shared network location, verify the MAC 5 is still connected to the network.
- Check for a disconnected LAN cable, loose Ethernet connector, docking or network adapter issue, WLAN disconnection, weak wireless signal, network settings changes, or a shared folder that is no longer reachable.
- Expected: The MAC 5 has a stable network connection before continuing the upgrade.
- Why it matters: The error can occur if the device loses access to the network upgrade source during manual upgrade.
Verify LAN or WLAN Connection
- For wired network use, reseat the Ethernet cable at both the MAC 5 and wall jack or network adapter.
- For wireless use, confirm the device is connected to the correct WLAN and has adequate signal.
- If available, test the network jack or cable with a known-good device, or move the MAC 5 to a known-good network connection.
- Expected: Network access is restored and stable.
Confirm the Network Shared Upgrade Location Is Available
- Verify the shared network path used for the upgrade is still available and correctly configured.
- Confirm the software image and required digital signature files remain in the shared folder.
- Expected: The MAC 5 can access the same network location used at the start of the upgrade.
- Why it matters: Reconnecting the network alone may not help if the shared folder or upgrade files are unavailable.
Continue or Retry the Upgrade
- Once the USB flash drive is reinserted or network connection is restored, continue the upgrade if the device allows it.
- If continuing is not available, restart the upgrade process using the same validated upgrade source.
- Expected: The upgrade resumes or restarts without the same error.
Stop When Resolved
- If reinserting the USB flash drive or restoring the network connection resolves the error, allow the upgrade to complete fully.
- Do not remove the USB drive, disconnect network cables, power off the device, or move the device during upgrade unless instructed by approved service documentation.
- After completion, verify the MAC 5 boots normally and is functional before returning it to service.
- Expected: Device upgrade completes and the MAC 5 is safe for clinical use.
If the Problem Persists
If the error continues after confirming a stable USB source or stable network connection, external and common causes have been ruled out.
Persistent failure may indicate an intermittent USB port issue, unstable network hardware, invalid or unreadable upgrade media, shared folder access issue, software upgrade process failure, or internal device fault requiring bench evaluation.
Remove the MAC 5 from service, label it Out of Service, and send it for repair or further bench evaluation.
Clinical Use Tip
Never troubleshoot a software upgrade problem on an active patient. Move the patient to a backup ECG machine first, maintain testing continuity, and only return the MAC 5 to service after the upgrade status and basic function are verified.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"MAC 5 displayed error 'Plug in the USB or Connect the Device to the Network and Then Continue the Upgrade Progress' during manual software upgrade. Upgrade could not continue after source media or network connection was interrupted."
Cause
What was observed during troubleshooting.
Example:
"USB flash drive was removed or network connection was lost during manual upgrade. External upgrade source connection required verification before continuing."
Resolution
What action was taken.
Example:
"Removed device from service during troubleshooting. Reinserted USB flash drive or restored network connection, verified upgrade source was available, retried upgrade, and confirmed device completed upgrade and booted normally. Returned to service after functional check."
Helpful Details to Include (If Known)
- Alarm behavior or exact error behavior during the upgrade
- Accessories swapped, including USB flash drive, Ethernet cable, or network adapter
- Power behavior during the upgrade attempt
- Environmental factors such as device movement, weak WLAN signal, or unstable network location
- Indicator lights, network icon status, USB detection behavior, or connection status
- Final device status, including whether the upgrade completed and whether the MAC 5 was returned to service or sent for repair
Final Thought
Software upgrade errors should be handled carefully because interrupted upgrades can affect device readiness. Start with patient safety, confirm the exact error, restore the USB or network upgrade source, and only escalate after external causes are ruled out. Clear CCR documentation protects both the repair history and the clinical workflow.
That is successful troubleshooting.
