What This Guide Helps With
Troubleshooting an Agilia pump not detected by a Link or Link+ docking station due to seating, power, contacts, compatibility, or external damage.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
Do not remove, reseat, or test a pump in the docking station while it is actively delivering medication to a patient.
- Notify the responsible clinical staff.
- Transfer the infusion to another verified pump or approved power arrangement when continued therapy is required.
- Confirm that the medication line remains secured during the transfer.
- Use additional caution with vasoactive, sedating, high-alert, or short-half-life medications.
Expected outcome: Patient therapy continues safely without depending on an uncertain docking connection.
2. Confirm the Exact Recognition Problem
Determine whether:
- The docking station does not indicate that a pump is installed.
- The pump does not receive external power.
- The pump receives power but is not shown on the docking station display.
- The problem occurs in one docking position or every position.
- The problem follows one specific pump.
- An error message, missing slot indicator, or communication alarm appears.
Record the complete message and affected docking position.
Expected outcome: The failure is identified as pump-specific, slot-specific, or docking-station-wide.
3. Verify Docking Station Power
Confirm that:
- The docking station power cord is fully connected.
- The cord and plug have no cuts, bent pins, exposed conductors, or strain damage.
- The docking station is connected to a known-good hospital-grade outlet.
- The outlet has been tested with an approved electrical tester or known-good device.
- The docking station’s power and status indicators illuminate normally.
Do not use an extension cord or unapproved power strip.
Expected outcome: The docking station powers normally and is available to detect installed pumps.
If restoring power resolves the issue, functionally verify the affected position and stop.
4. Inspect the Pump and Docking Position Externally
Remove the pump from service before inspecting it.
Check the pump and docking position for:
- Cracked or damaged mounting surfaces.
- Bent, recessed, loose, or contaminated contacts.
- Dried medication, cleaning residue, dust, or foreign material.
- Damage to the pump’s rear docking interface.
- Obstruction around the locking or retention mechanism.
- Signs that the pump was dropped or forced into the station.
Do not insert tools into connectors or attempt to straighten contacts while the equipment is energized.
Expected outcome: The docking interfaces are clean, dry, unobstructed, and visibly undamaged.
5. Clean Accessible Contact Surfaces
Disconnect docking-station power before cleaning when required by facility procedure.
- Use only a manufacturer-approved cleaning method and product.
- Apply cleaner to a cloth rather than spraying directly into the station.
- Remove visible residue from accessible external contact surfaces.
- Allow all surfaces to dry completely before reconnecting power.
- Do not scrape contacts or use abrasive materials.
Expected outcome: Clean and dry contacts provide a reliable electrical and communication connection.
If cleaning restores recognition, complete functional verification and stop.
6. Reseat the Pump Correctly
Align the pump squarely with the docking position and install it without excessive force.
Confirm that:
- The pump follows the docking guides.
- The pump is pushed fully into position.
- The locking or retention mechanism engages.
- The pump sits level and does not rock or remain partially inserted.
- The appropriate external-power or docking indication appears.
Fresenius Kabi describes Agilia pumps as capable of rack-mounted operation and its Link/Link+ products as pump-centralization systems.
Expected outcome: The pump locks into position and is recognized by the docking station.
If proper seating resolves the issue, test the pump in that position more than once and stop.
7. Test the Pump in Another Known-Good Position
Install the same pump into another verified docking position.
- If the pump is recognized elsewhere, the original position is likely defective.
- If the pump is not recognized in any position, the problem may be associated with the pump.
- Do not repeatedly force the pump into a position that does not accept it normally.
Expected outcome: The test separates a docking-position failure from a pump-interface failure.
8. Test a Known-Good Pump in the Suspect Position
Use another compatible Agilia pump that is known to dock correctly.
- If the known-good pump is also not recognized, suspect the docking position or station.
- If the known-good pump is recognized, suspect the original pump’s docking interface.
- Confirm that both pumps are approved for use with the installed docking-station configuration.
Expected outcome: The failure consistently follows either the pump or the docking position.
9. Verify Pump and Docking-Station Compatibility
Confirm that:
- The pump type is supported by the specific Link or Link+ configuration.
- The pump and docking station are approved for use together at the facility.
- No recent pump replacement, software update, configuration change, or fleet conversion preceded the problem.
- The affected pump is not from a different regional or system configuration.
Do not change service-level configuration without authorization and approved documentation.
Expected outcome: The pump and docking station are confirmed to be compatible.
10. Perform a Controlled Power Reset
Only after removing all active infusions:
- Remove all pumps from the docking station.
- Disconnect the docking station from AC power.
- Wait according to facility procedure.
- Reconnect the docking station to a known-good outlet.
- Allow it to complete startup.
- Install one known-good pump and check recognition.
- Reinstall additional pumps one at a time.
Expected outcome: The docking station completes a normal startup and recognizes each compatible pump.
If recognition returns, verify every affected position before returning the equipment to service.
11. Check for a Capacity or Position-Specific Pattern
When multiple pumps are installed, determine whether:
- Only one position fails.
- All positions after a certain point fail.
- Recognition fails only when the station is fully populated.
- The failure appears after a particular pump is installed.
- Indicators flicker or reset when pumps are added.
Remove the suspect pump and retest the remaining positions.
Expected outcome: The test identifies a defective pump, docking position, connection path, or station-wide loading problem.
12. Complete Functional Verification
Before returning either component to service:
- Confirm stable pump recognition.
- Verify external-power indication where applicable.
- Confirm the pump remains detected when gently checked for secure seating.
- Verify normal docking-station indicators.
- Check every position involved in the complaint.
- Confirm that no communication or power error returns.
- Perform required electrical-safety and operational testing according to facility policy.
Expected outcome: The pump and docking station operate normally and consistently.
Do not return equipment to service based on a single successful connection.
If the Problem Persists
If known-good pumps are not recognized in a specific position, or the original pump is not recognized in any known-good position, common external causes have been ruled out.
The affected pump, docking station, or both should be:
- Removed from service.
- Labeled Out of Service.
- Identified clearly as pump-specific or docking-position-specific.
- Sent for authorized repair or bench evaluation.
- Evaluated using the applicable Fresenius Kabi service documentation and approved test equipment.
Do not open the docking station or pump for board-level troubleshooting unless you are trained, authorized, and following an approved service procedure.
Knowing when to stop is proper troubleshooting.
Clinical Use Tip
Never troubleshoot docking recognition by repeatedly removing an actively infusing pump. Transfer the patient safely first, then test the pump and docking station away from clinical use.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported that an Agilia pump was not recognized when installed in position three of the Link docking station."
Cause
What was observed during troubleshooting.
Example:
"A known-good pump also failed in position three, while both pumps were recognized normally in other docking positions, confirming a position-specific docking-station failure."
Resolution
What action was taken.
Example:
"Removed the docking station from service, labeled it Out of Service, provided a replacement station, and routed the affected unit for authorized bench evaluation."
Helpful Details to Include (If Known)
- Outlet tested
- Docking-station power indicators observed
- Pump external-power indication checked
- Pump reseated correctly
- Contacts inspected and cleaned
- Known-good pump tested
- Alternate docking position tested
- Exact affected position documented
- Displayed error or alarm recorded
- Compatibility verified
- Unusual sounds noted
- Unusual heat or smell noted
- Evidence of fluid ingress or impact noted
- Final pump status documented
- Final docking-station status documented
Final Thought
Safe troubleshooting begins by protecting the patient, then separating pump-specific failures from docking-position and station-wide problems. Logical substitution testing and complete CCR documentation support appropriate repair escalation.
That is successful troubleshooting.
