| Warning
Read the installation instructions before you connect the system to its power source. |
| Warning
Only trained and qualified personnel should be allowed to install or replace this equipment. |
| Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. |
| Warning Ultimate disposal of this product should be handled according to all national laws and regulations. |
| Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. |
| Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Both LAN and WAN ports may use RJ-45 connectors. Use caution when connecting cables. |
| Warning Hazardous network voltages are present in WAN ports regardless of whether power to the router is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first. |
| Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. |
| Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity. |
| Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is OFF and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. |
Follow these guidelines when working on equipment powered by electricity:
If an electrical accident occurs, proceed as follows:
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur when printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the router chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To guard against ESD damage and shocks, the wrist strap and cord must be used properly. If no wrist strap is available, ground yourself by touching the metal part of the chassis.
 | Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohm). |
The equipment described in this document generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco's installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
You can determine whether your equipment is causing interference by turning it OFF. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.
To install a fan-speed controller in a Cisco 3620 router, you need the following tools and equipment (some of which are not included in the fan-speed controller kit):
This section describes how to remove the cover. You must remove the chassis cover to gain access to the power supply and fan connectors.
Take the following steps to remove the cover:
Step 1 Turn OFF power to the router and unplug the power cable.
| Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. |
Step 2 Remove all network interface cables from the rear panel.
Step 3 Position the router so the front panel is facing you. Remove the three screws located on top of the cover near the front edge. (See Figure 1.) Set the screws aside in a safe place.
Step 4 Lift the front edge of the cover until the cover clears the front of the chassis.
(See Figure 1.)
Step 5 Pull the cover toward you until the metal tabs on the rear edge separate from the chassis bottom. (See Figure 2.)
Step 6 Lift the cover free and set it aside.
When you are ready to replace the cover, see the "Replacing the Cover" section.
This procedure describes how to install the fan-speed controller in the router:
Step 1 Unplug the fan connectors from the power supply connectors. (See Figure 3.)
Step 2 Remove the two screws, located near the power supply, from the motherboard. (See Figure 4.) Save these screws for later reinstallation.
Step 3 Connect the two fan connectors to the two fan-speed controller connectors. (See Figure 5.)
Step 4 Connect any one of the two power supply connectors to the single fan-speed controller power connector. (See Figure 5.)
Step 5 Position the fan-speed controller bracket so that the card is on the top side, and the holes in the bracket and motherboard are aligned. (See Figure 5.)
Step 6 Secure the bracket to the motherboard with the screws removed in Step 2. (See Figure 5.)
This section describes how to replace the router cover:
Step 1 Position the router so the front panel is closest to you.
Step 2 Hold the cover so the tabs at the rear of the cover are aligned with the chassis bottom.
(See Figure 6.)
Step 3 Push the cover toward the rear, making sure that the cover tabs fit under the rear panel of the chassis, and the chassis tabs fit under the top cover.
Step 4 Lower the front of the cover onto the chassis, making sure that the tabs on the side of the cover fit inside the chassis side panels, and the tabs on the side of the chassis fit under the cover side panels.
Step 5 Fasten the cover with the three screws you set aside in Step 3 of the "Removing the Cover" section.
Step 6 Reinstall the chassis on a rack, desktop, or table. (See your router installation and configuration guide for installation procedures.)
Step 7 Reinstall network interface cables.
If the router does not power on, see your router installation and configuration guide for troubleshooting procedures.
