Safety Warnings

Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may harm you. A warning symbol precedes each warning statement. The following warning is an example of a safety warning. It identifies the warning symbol and associates it with a bodily injury hazard.

---

Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompany this device.

---

Preventing Electrostatic Discharge Damage

Many router components can be damaged by static electricity. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, always use an ESD-preventive antistatic wrist strap (or ankle strap) and ensure that it makes good skin contact.

---

Note You should periodically check the resistance value of the ESD-preventive strap. Ensure the measurement is between 1 and 10 megohms.

---

Before performing the procedures in this guide, attach an ESD-preventive strap to your wrist and connect the leash to the chassis or to another grounded, bare metal surface as shown in Figure 1.

Figure 1 Connecting an ESD-preventive Wrist Strap to the Chassis

Installation Guidelines

Read the following guidelines before removing and replacing a DC PEM or PDU.

DC PEM Guidelines

The DC PEM supports online insertion and removal (OIR), so you can remove and install the PEM while the system remains powered on without presenting an electrical hazard or damage to the system. This feature lets you replace the AC PEM while the system maintains all routing information and ensures session preservation.

---

Caution Although a DC PEM supports OIR and can be replaced without interruption to system operation, do not operate the system without the PEM for more than a few minutes.

---

DC PDU Guidelines

The DC PDU does not support online insertion and removal (OIR) and cannot be replaced while the system is operating. You must power off the router before replacing the PDU.

---

Warning To remove and replace the DC PDU, the system must be powered off. Notify the network administrator and other appropriate personnel that all routing traffic stops while the PDU is replaced.

---

Tools and Equipment

You need the following tools and this equipment to remove and replace the fan tray assembly:

•ESD-preventive strap

•3/16-inch flat-blade screwdriver

•Number 1 Phillips screwdriver

Removing and Replacing a DC Power Entry Module

Refer to Figure 2 and use the following procedure to remove and replace a DC PEM.

---

Step 1 Power off the faulty PEM.

Step 2 Power off the circuit breaker assigned to the DC power source. Verify that all LEDs are off.

Step 3 Loosen the three captive screws that secure the PEM to the chassis.

Step 4 Remove the PEM from the chassis using the finger grips to pull it out.

---

Warning A DC PEM weighs approximately 11.0 lbs. (4.98 kg). Use both hands to remove it from the chassis.

---

Troubleshooting a PEM Installation

Refer to Figure 3 and use the following procedure to troubleshoot a PEM installation.

Figure 3 DC PEM Status LEDs

1	DC PDU	n/a	DC PDU
2	DC PEM	n/a	DC PEM
3	INPUT OK (Green)	On	DC PEM is operating normally in a power-on condition
4	OUTPUT OK (Green)	On	DC power source is present and within specified limit
5	OUTPUT FAIL (Amber)	On	PEM is operating in a fault condition and shutdown has occurred

---

Step 1 If the Input OK and Output OK LEDs are off, or if the Output Fail LED is on, check that the:

•PEM is firmly seated in the bay and the captive screws are tightened securely.

•DC power source circuit breaker is switched on.

•Power switch is set to the on (1) position.

Step 2 If the problem still exists after checking the items in Step 1, replace the PEM.

Step 3 If replacing the PEM does not correct the problem, contact a Cisco service representative for assistance.

---

Removing and Replacing a DC PDU

The DC PDU does not support online insertion and removal (OIR) and cannot be replaced while the system is operating. You must power off the router before replacing the PDU.

---

Warning To remove and replace the DC PDU, the system must be powered off. Notify the network administrator and other appropriate personnel that all routing traffic stops while the PDU is replaced.

---

Refer to Figure 4 and use the following procedure to remove and replace a DC PDU.

---

Step 1 Power off both PEMs.

Step 2 Power off the circuit breakers assigned to the DC power source.

Verify that all status LEDs on both PEMs are off.

Step 3 Loosen the terminal block screws to disconnect the positive, negative, and ground wires from the DC PDU terminal block of the faulty PEM.

---

Caution Before removing wires, be sure to note the color for each type of wire (positive, negative, and ground). Because there is no color code standard for source DC wiring, you must be sure which power wires are connected to the proper positive (+) and negative (-) terminal ports. Typically, green (or green and yellow) indicate a ground wire, while power wire leads may be labeled positive (+) or negative (-). Because this is not always the case, the safest way to indicate the polarity of a wire is to note its color and identify it as described in this procedure.

---

---

Warning When disconnecting source DC power wires, always disconnect the ground wire last.

---

Step 4 Loosen the captive screws securing the PDU and the PEM to the chassis.

Step 5 Remove the PDU/PEM from the chassis using the finger grips to pull it out.

---

Warning A DC PEM and PDU weigh more than 11.0 lbs. (4.98 kg). Use both hands to remove it from the chassis.
