Left: Ethernet drives. 5 Disconnect the tape drive power cable assembly from the rear panel of the tape drive that sits in front of the failed fan module. 2U Rackmount Component Replacement Guide 23 Chapter 3 Fans Removing a Failed Fan Module 6 Move the tape drive power cable assembly out of the way as follows: a b Gently lift the fan module upward just a little. While holding the fan module up, pull the tape drive power cable assembly through a slot in the fan mounting wall and under the fan module (see figure 18). Note: Be sure to align the power cable connector so that it passes through the slot easily. To avoid personal injury or damaging the power cable assembly or connector, apply only light pressure when pulling the cable through the fan mounting wall. Caution: Figure 18 Tape Drive Power Cable Assembly under Fan Module c d Allow the fan module to return to its original position. Pull the tape drive power cable assembly through the opening in the power supply compartment wall (the opening is near the fan mounting wall) (see figure 19). 2U Rackmount Component Replacement Guide 24 Chapter 3 Fans Removing a Failed Fan Module Figure 19 Tape Drive Power Cable Assembly to Power Supply Compartment e Lay the tape drive power cable assembly on top of the power supply. 7 Disconnect the fan module cabling from the PCBA (see figure 20). 8 Pull the fan module cabling (front to back) through the fan mounting wall and through the power supply retaining wall (see figure 20). Lay the cable in the open area behind the fan module. 2U Rackmount Component Replacement Guide 25 Chapter 3 Fans Removing a Failed Fan Module Figure 20 Disconnecting the Fan Module Cabling from the PCBA 9 Lift the fan module vertically out of the 2U Rackmount. 2U Rackmount Component Replacement Guide 26 Chapter 3 Fans Installing a Fan Module Installing a Fan Module To install a fan module in the 2U Rackmount unit, follow these steps: 1 Lower the fan module vertically into the 2U Rackmount. 2 Push the fan module cabling through the power supply retaining wall and (back to front) through the fan mounting wall. Tech Tip: Before pushing the fan module cabling through the fan mounting wall, bend the cable about 90°, 4 to 5 cm (1. 5 to 2 inches) above the fan module connectors, and then align the connectors in the fan mounting wall opening. 3 Connect the fan module cabling to the connectors on the PCBA. Note: There are six connectors on the PCBA -- choose any two on each side per fan module. 2U Rackmount Component Replacement Guide 27 Chapter 3 Fans Installing a Fan Module 4 Move the tape drive power cable assembly from the power supply compartment to the tape drive rear panel as follows: a Gently pull the tape drive power cable assembly through the opening in the power supply compartment wall (see figure 21).

This chapter describes how to perform these tasks: · Removing a Power Supply · Installing a Power Supply Warning: Electric Shock Hazard. Voltage or current sufficient to cause shock, burn, or death may be present on the power supply. To reduce exposure to electric shock: - Disconnect power from the 2U Rackmount before performing any service. - Replace the power supply unit as a whole. Figure 24 shows the power supply location in the unit. It also shows the location of other unit components mentioned in the procedure. 2U Rackmount Component Replacement Guide 31 Chapter 4 Power Supply Removing a Power Supply Figure 24 Power Supply and Adjacent Walls Power supply Rear retaining bracket Ground wire Front retaining bracket Power Supply Compartment Walls Fan Mounting Wall PCBA Removing a Power Supply To remove a power supply from the 2U Rackmount: 1 Turn off the host computer and all peripheral devices.
