You have completed the procedure for replacing the Cisco ESP5 or ESP10. Replace the Shared Port Adapters The shared port adapters (SPAs) on the embedded Cisco ASR1000-SIP10 in the Cisco ASR 1002 Router support online insertion and removal (OIR); but the embedded Cisco ASR1000-SIP10 does not support OIR and is not field-upgradeable. Note Cabling information is included with the specific shared port adapter documentation. Before removing any shared port adapter, shut down the interface so that there is no traffic running through the shared port adapter when it is removed. Removing a shared port adapter while traffic is flowing through the ports can cause system disruption. Step 1 Step 2 Step 3 Step 4 Attach an ESD wrist strap between you and an unpainted chassis surface. Disconnect all cables from the shared port adapter. Remove the shared port adapter from the chassis subslot. Grasp the handle and pull the shared port adapter or blank panel from the router. Locate the shared port adapter slot guides inside the Cisco ASR 1002 Router. Caution The shared port adapter must slide into the slot guides under the chassis lid. Do not allow the shared port adapter components to come in contact with the system board or the shared port adapter could be damaged. Step 5 Step 6 Step 7 Step 8 Carefully slide the shared port adapter into the shared port adapter slot until it is firmly seated and then securely tightened the captive screws. When installed, the shared port adapter input/output panel should be flush with the face of the router. Reconnect any cables and place the cables through the cable-management brackets. If the shared port adapter fails to come up, reseat or reinsert the shared port adapter; do not use excessive force. Power on the router by turning the power switch to the on (I) position. Replace a Power Supply in the Cisco ASR 1002 Router This section provides instructions for removing the AC power supply, the -48V DC and +24V DC power supply from a Cisco ASR 1002 Router. This section contains the following topics: • Removing an AC Power Supply, page 41 • Removing the -48V DC Power Supply, page 42 • Removing the +24V DC Power Supply, page 42 Before you begin, make certain the chassis is grounded. Note Two power supplies must be installed in the chassis at all times to ensure sufficient cooling. The system fans are inside the power supply units and must spin for cooling. Because all the system fans can be powered by one power supply, the second power supply unit does not have to be powered on, but it must be installed. Caution If you remove a power supply, the system can run for a maximum of five minutes before the system shuts down. The fans and power elements are independent within the power supply. Therefore, it is not required that the replacement power supply be energized within five minutes. The only requirement is that the power supply be installed in the chassis, which energizes the fans and maintains proper system cooling. 40
