Left and Right Chassis Fan Removal and Replacement

Purpose

Provides instructions to:

1. Remove Left and Right Chassis Fans from Panther Systems below Serial # 00281.
2. Install Left and Right Dual Chassis Fan Assemblies, which were cut-in on Panther Systems above Serial # 00280.

Parts and Materials Required

• Proper PPE
• Diagonal cutters (small)
• 8 Inch cable-ties (as needed)
• 4 mm Allen wrench
• Nitrile gloves
• Dual chassis fan, left

  

• Dual chassis fan, right

  

Preparation

1. Put on proper PPE.
2. Prepare the system for service.
3. Power down the Panther System.
4. Open both side panels of the system.
5. Pull open the Service drawer and leave it fully extened for the entire procedure.
6. Read the rest of this procedure before starting it.

Procedure

Removing and Replacing the Right Chassis Fan Assembly

1. Unplug the 4-pin fan connector from the PCB (shown unplugged).

   

2. Pull the fan cable through the chassis of the system.

   

3. Remove the chassis fan from the bracket by sliding the rubber mounts up.

   

4. Using a 4 mm Allen wrench, loosen but do not remove the 2 M6 bracket mount screws on the back side of the bracket. (Screw location approximated by red arrows.)

   

5. Slide the bracket up to remove it from the system.
6. Using a 4 mm Allen wrench and the same mounting screws from the original bracket, install the new dual right chassis fan assembly [P/N 902976].

   NOTE—Make sure the bracket is pushed all the way down before tightening the mounting screws.

   

7. Route the fan cable through the cable routing openings in the chassis.
8. Replace all removed zip-ties in the same fashion as the original fan assembly.
9. Plug the 4-pin connector into the circuit board.
10. Test the Waste Drawer opening & closing for cable snags & obstructions. Adjust as needed.
11. Close the right side door panel.

Removing and Replacing the Left Chassis Fan Assembly

1. Unplug the 3-pin fan connector from the COP circuit-board.

   

2. Unclip the wire-clips identified and feed the fan cable through the chassis of the system.

   NOTE—Make sure to remove any cable-ties holding the fan cables prior to pulling the fan cable.

   

3. Using a 4 mm Allen wrench, loosen, but not remove, the 2 M6 bracket screws and slide the bracket towards the back of the system to remove it from the system.

   

4. Using the same mounting screws used with the original bracket, install the new dual left chassis fan assembly [P/N 903165].

   

5. Route the fan cables through the cable routing openings in the chassis and cable-clips.
6. Replace all removed cable-ties in the same fashion as the original fan assembly.

   

7. Plug the 3-pin connector into the COP circuit board.

   

8. Test the Service Drawer opening & closing for cable snags & obstructions, adjust as needed.
9. Close the left side door panel.
10. Proceed to Verification.

Verification

1. Initialize the system by using one of the following methods:
1. Method 1:
1. Launch Panther Software and allow the system to initialize.
2. Select Shutdown when in setup status
2. Method 2:
1. Launch Service Software and
2. Initialize by inputting the following hex command into the Service Software command terminal:
   
   02 48 00 00 1E 00 10 02 02 1D 00 10 00 00 00 80 00 00 00 00 B0 04 00 00 00 00 00 00 00 00 00
2. Verify that the dual chassis fan, right, is properly connected by turning the fan ON and OFF by inputting the following hex commands in the Panther Service Software command terminal:
1. Turn Dual Chassis Fan, Right, ON:
   
   18 08 00 00 0E 01
2. Turn Dual Chassis Fan, Right, OFF:
   
   18 08 00 00 0E 00
3. Verify that the dual chassis fan, left, is properly connected by turning the fan ON and OFF by inputting the following hex commands in the Panther Service Software command terminal:
1. Dual Chassis Fan, Left, ON:
   
   04 08 00 01 00 01
2. Dual Chassis Fan, Left, OFF:
   
   04 08 00 01 00 00
4. Verification is complete.
