FCC ID: F8I-DISSMRAA, Partial User Manual, 4 of 4 ADCP-75-136 • Issue 1 • November 2002 3. Connect the DC power cable to the RJ-45 circuit access tool (see Figure 28). 4. Using a DC voltmeter, verify that the DC voltage level is between 34 and 48 Vdc between any set of positive and negative (+/-) terminals at the RJ-45 circuit access tool as shown in Figure 29. Due to source current limiting at the DHU or DEU, low voltage can mean excess wire resistance, low source voltage, or excess remote current. Warning: The DRU uses 48 Vdc power. To avoid electric shock or burns, use extreme care when working near exposed terminals or uninsulated cables. Be careful not to touch exposed terminals or to cause a short between terminals when checking voltage levels. POSITIVE (+) NEGATIVE (-) TEST POINTS TEST POINTS 1, 3, 5, AND 7 2, 4, 6, AND 8 16206-B Figure 29. RJ-45 Circuit Access Tool Pin/Wire Designations 5. Disconnect RJ-45 circuit access tool from the DRU. 6. Use the DC voltmeter to check for open pin connections by checking for voltage between the +/– pairs on the RJ-45 circuit access tool (see Figure 29). 7. Disconnect the DC power cable from the RJ-45 circuit access tool. 8. Re-connect DC power cable to the DRU. 6.5 DHU or DEU Fan Replacement Procedure It is recommended that the fans (catalog # DGVI-100000FAN) be replaced every five years. Replacement of a fan requires that the DHU or DEU be turned off for a short period of time. This will drop all existing calls, cause a temporary loss of service, and generate a major alarm. Use the following procedure to replace the cooling fans within the DHU or the DEU: 1. Before touching the DHU or DEU or handling a fan, slip on an Electro-Static Discharge (ESD) wrist strap and connect the ground wire to an earth ground source. Wear the ESD wrist strap while completing each section of the fan installation procedure. Warning: Electronic components can be damaged by static electrical discharge. To prevent ESD damage, always wear an ESD wrist strap when working on the DHU or DEU and when handling electronic components. 2. Observe the fans (located on right side of enclosure) to determine which fan requires replacement. The faulty fan may be stopped, running at a reduced speed, or the fan bearing may be noisy. Note: Because the Mean Time Between Failures (MBTF) is the same for both fans, it may be more efficient to replace both fans at the same time. Page 53 © 2002, ADC Telecommunications, Inc.

ADCP-75-136 • Issue 1 • November 2002 3. Notify the NOC or alarm monitoring system operator that the system is going offline. 4. Place the DHU or DEU AC power On/Off switch (see Figure 3 or Figure 7) in the OFF position (press O). 5. Remove the six flat-head screws (requires TORX screwdriver with T15 bit) that secure the fan/grill assembly to the side of the enclosure as shown in Figure 30 and save for reuse. 16172-B Figure 30. Fan/Grill Assembly Removal 6. Carefully withdraw the fan/grill assembly from the enclosure until the wiring harness is exposed and the connectors are accessible. 7. Lift the small latch on each wiring harness connector (see Figure 30) and carefully unplug each connector from the circuit board connector. 8. Remove the four plastic rivets that secure the faulty fan to the grill by pushing outward on rivet center post until the rivet can be withdrawn from the grill as shown in Figure 31. 9. Remove the faulty fan(s) from the grill and then locate the replacement fan(s). 10. Use the rivets removed in step 8 to secure the replacement fan to the grill. Orient the fan so the wiring harness is on the top and the arrow on the fan housing faces into the enclosure. 11. Connect the two wiring harness connectors to the circuit board connectors. 12. Secure the fan/grill assembly to the side of the enclosure (see Figure 30) using the six flat-head screws removed in step 5. Page 54 © 2002, ADC Telecommunications, Inc.

ADCP-75-136 • Issue 1 • November 2002 16173-B Figure 31. Removing Fan From Grill 13. Place the DHU or DEU AC power On/Off switch in the ON position (press I). 14. Verify that the fans run properly following power up. 15. Notify the NOC or alarm monitoring system operator that the system is going back online. 6.6 DHU or DEU Modular Optical Transceiver Replacement Procedure The modular optical transceiver should be replaced when testing indicates that the transceiver has failed. Use the following procedure to replace an optical transceiver in a DHU or DEU: Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transceiver of any digital unit or exposure to laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating transceiver or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the transceiver or connector. 1. Put on the IR filtering safety glasses. 2. Slip on an Electro-Static Discharge (ESD) wrist strap and connect the ground wire to an earth ground source such as the grounding stud on the DHU or DEU front panel. Wear the ESD wrist strap while completing the optical transceiver replacement procedure. Warning: Electronic components can be damaged by static electrical discharge. To prevent ESD damage, always wear an ESD wrist strap when handling electronic components. 3. Place the PORT ON/OFF switch for the optical transceiver being replaced in the OFF position (press O).

ADCP-75-136 • Issue 1 • November 2002 Note: The HOST PORT on the DEU does not have an On/Off switch and can only be disabled by placing the DEU AC power On/Off switch in the OFF position (press O). Turning off the power to the DEU will create an alarm condition. If the DEU must be turned off, inform the NOC or alarm monitoring system operator that an alarm will be reported. 4. Disconnect the optical fiber connectors from the optical transceiver and place a dust cap over each connector. 5. Release the optical transceiver from the transceiver socket by pulling outward on the release lever (if type A) or release tab (if type B) as shown in Figure 32.

DHU or DEU Optical Transceiver Removal 6. Remove the optical transceiver from the transceiver socket. 7. For replacement, select an optical transceiver that corresponds to the type of fiber (single- or multi-mode) used in the installation. The color of the transceiver corresponds to the transceiver fiber type (see Figure 32). 8. Remove the optical transceiver from the anti-static packaging and orient for installation as shown in Figure 33. Note: Two types of optical transceivers, type A and type B, are available. Both types provide the same functionality. On the type A optical transceiver, the release lever (see Figure 33) must be closed for installation. Page 56 © 2002, ADC Telecommunications, Inc.
