Remove DC Input Power from Cisco 4461 or 4431 ISR

This section describes how to remove a DC power supply from Cisco 4461 or 4431 ISR.

Note The Cisco 4431 ISR has redundant power supplies that can be hot-swapped.

To remove a DC power supply from Cisco 4461 or 4431 ISR:

Step 1 If you have redundant power supplies, ensure that the power switch is in the standby position.

Note You do not require to place the power switch in the standby position if you want to hot-swap a single power supply.

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003

Warning To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

Step 2 For Cisco 4461 ISR and Cisco 4431 ISR, unscrew the two terminal block wire connectors (negative and positive) on the unit. See Figure 5-40.

For Cisco 4451 ISR and Cisco 4351, unscrew the three terminal block wire connectors (ground, negative and positive) on the unit. For Cisco 4331 ISR, remove the power supply cable connector (See Figure 5-41) and remove the two screws that secure the power supply module to the chassis.

Step 3 [Only for Cisco 4461, 4431, and 4331 ISRs] Remove the plastic bezel from the router.

Step 4 Press the retaining latch towards the pull handle, grasp the handle with one hand, and pull the power supply out of the slot while supporting the weight of the power supply with the other hand. See Figure 5-37.

Figure 5-37 Remove DC Power Supply

Install DC Input Power on Cisco 4431 ISR

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

This section describes how to install the DC power supply input power leads to the Cisco 4431 Router DC input power supply.

• The color coding of the DC input power supply leads depend on the color coding of the DC power source at your site. Ensure that the lead color coding you choose for the DC input power supply matches the lead color coding used at the DC power source. Verify that the power source is connected to the negative (–) terminal and to the positive (+) terminal on the power supply.
• Ensure that the chassis ground is connected on the chassis before you begin installing the DC power supply. Follow the steps provided in the “Chassis Grounding” section.

Wire the DC Input Power Source

The Cisco 4431 ISR DC power supply has a terminal block that is installed into the power supply terminal block header.

To wire the DC input power source:

Step 1 If you have redundant power supplies, ensure that the power switch is in the standby position.

Note You do not require to place the power switch in the standby position if you want to hot-swap a single power supply.

Step 2 Insert the power supply in the power-supply slot, and gently push it into the slot. When correctly installed:

• For Cisco 4431 ISR, the DC power supply (excluding the extraction handle) is flush with the router.
• For Cisco 4451 ISR and Cisco 4351ISR, the DC power supply (excluding the extraction handle) is recessed from the router bezel.

Step 3 Wire can be stripped and terminated directly to the power supply terminal block, or a crimp style spade terminal lug can be used. If you are using a terminal lug, follow the manufacturer's instructions for terminating the lug to the wire. If terminating directly to the terminal block using bare wire, follow the instructions in the Figure 5-40. Use a wire-stripping tool to strip each of the two wires coming from the DC input power source and strip the wires to approximately 0.39 inch (10 mm) + 0.02 inch (0.5 mm). We recommend that you use 14 AWG insulated wire. Do not strip more than the recommended length of wire because doing so could leave the wire exposed from the terminal block. Figure 5-38 shows a stripped DC input power source wire.

Figure 5-38 Stripped DC Input Power Source Wire

Warning An exposed wire lead from a DC input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC input power source wire extends from the terminal block. Statement 122

Step 4 Identify the positive and negative feed positions for the terminal block connection. The wiring sequence is:

1. Positive (+) lead wire (right)

2. Negative (–) lead wire (left)

Step 5 Remove the router bezel. See Figure 5-39. The bezel is secured with snap latches. To remove the bezel, hold the top and bottom and pull the bezel.

Figure 5-39 Remove the Bezel

This section describes how to install the DC power supply input power leads to the Cisco 4331 Router DC input power supply.

• The color coding of the DC input power supply leads depend on the color coding of the DC power source at your site. Ensure that the lead color coding you choose for the DC input power supply matches the lead color coding used at the DC power source and verify that the power source is connected to the negative (–) terminal and to the positive (+) terminal on the power supply.
• Ensure that the chassis ground is connected on the chassis before you begin installing the DC power supply. Follow the steps provided in the “Chassis Grounding” section.

Wire the DC Input Power Source on Cisco 4331 ISR

The Cisco 4331 ISR DC power supply supports 12V/21A output with the DC input range from 24 to 60 VDC.

Note The input current should be less than 6.3 A at 48 VDC. It is recommended to use slow blow fuse and have the input fuse value less than or equal to 25 A.

The Cisco 4331 ISR DC power supply has a terminal block that is installed into the power supply terminal block header.

To wire the DC input power source:

Step 1 Ensure that the power switch is in the standby position.

Step 2 Insert the power supply in the power-supply slot, and gently push it into the slot.

Step 3 Wire can be stripped and terminated directly to the power supply terminal block, or a crimp style spade terminal lug can be used. If you are using a terminal lug, follow the manufacturer's instructions for terminating the lug to the wire. If terminating directly to the terminal block using bare wire, follow the instructions in the Figure 5-37. Use a wire-stripping tool to strip each of the two wires coming from the DC input power source and strip the wires to approximately 0.39 inch (10 mm) + 0.02 inch (0.5 mm). It is recommended that 14 AWG insulated wire be used. Do not strip more than the recommended length of wire because doing so could leave the wire exposed from the terminal block. Figure 5-38 shows a stripped DC input power source wire.

Figure 5-43 Stripped DC Input Power Source Wire

Warning An exposed wire lead from a DC input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC input power source wire extends from the terminal block. Statement 122

Step 4 Identify the positive and negative feed positions for the terminal block connection. The wiring sequence is:

1. Positive (+) lead wire (right)

2. Negative (–) lead wire (left)

Warning Care should be taken while removing the power supplies and power inverters (especially in boost mode of operation). If the total power consumption is higher than can be supported by one power supply alone and in this condition a power supply is removed, the hardware can be damaged. This may then result in the system being unstable or unusable.

The following messages are displayed as expected when you try to reload or insert a PoE supply in a router with Ethernet Switch Network Module:

Upon PoE converter power supply insertion, the inline power supply restores automatically in the router. After the insertion, resets are needed for the switch modules in the router for the PoE supply to work properly.

If there are two PoE supplies, the power supplies can operate in a boost mode or redundant mode. In a boost mode, the total power supplied is a sum of the two power supplies capacity. In a redundant mode, if one of the PoE supply fails, the other PoE supplies power.

Before Hot-Swapping a Fan Tray

Before hot-swapping a fan tray, read the safety precautions below.

• Read the entire procedure and have the required tools available.
• Do not attempt the hot-swap in ambient air temperature above 90°F (32°C).
• Do not attempt the hot-swap at an altitude above 6000 feet (1829 meters).
• When the router is being operated, we recommend to change the fans in the router within 2 minutes to ensure the router does not overheat:

Replace Fan Tray

Note If hot-swapping the fan tray, we recommend to complete the operation within two minutes to ensure the router remains within operating temperature.

Note We recommend that you change the air filter every 3 months. However, examine the air filter once a month (or more often in dusty environments) and replace it if it appears to be excessively dirty or damaged. To comply with Telecordia GR-63-Core standard air filter requirements for NEBS deployment, the air filter must be replaced, not cleaned.

Prevent Electrostatic Discharge Damage

CF memory cards are sensitive to electrostatic discharge (ESD) damage, which can occur when electronic cards or components are handled improperly. ESD results in complete or intermittent failures.

To prevent ESD damage, follow these guidelines:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
• Connect the equipment end of the strap to an unfinished chassis surface.
• Place CF memory cards on an antistatic surface or in a static shielding bag. If the card is to be returned to the factory, immediately place it in a static shielding bag.
• Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages on only the body; ESD voltages on clothing can still cause damage.
• Do not remove the wrist strap until the installation is complete.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).
