Interior Alarm Cables Overview
The interior alarm cables on Cisco 12010, Cisco 12410, and Cisco 12810 Routers provide the electrical and signaling connections between the system and the external alarm display panel. There are two internal alarm cables, which mate together to form the connection between the system and the external alarm display panel:
•Rear alarm cable (GSR10-DISP-RECBL=) runs up the back of the chassis, under the rear cover. This cable connects to a connector on the lower part of the backplane and runs up the chassis to just below the blower module, where it secures to a cutout in the chassis. (See Figure 1.)
•Front alarm cable (GSR10-ALRM-CBL=) mates with the rear alarm cable inside the chassis, just below the blower module, and is routed out the front of the chassis where it mates with the external alarm display panel. This cable has two grommets, which fit into cutouts in the chassis and act as cable guides. (See Figure 2.)

Interior Blower Cable Overview
The interior blower cable provides the router with electrical and signaling connections between the system and the blower module. In normal operation, the blower cable is concealed under the rear cover. One end of the blower cable provides a bulkhead-mounted connector that the blower module, when it is inserted from the front of the chassis, connects to. The cable is routed down the chassis rear panel where the other end connects to the chassis backplane. (See Figure 3.)

Safety Guidelines
Before you perform any procedure in this publication, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. In addition, review the safety warnings listed in the Regulatory Compliance and Safety Information for the Cisco 12000 Series Internet Router publication that accompanied your router before installing, configuring, or maintaining the router.
The following guidelines are for your safety and to protect equipment. The guidelines do not include all hazards. Be alert.
Safety with Equipment
•Always disconnect all power cords and interface cables before moving the system.
•Never assume that power is disconnected from a circuit; always check.
•Keep tools and assembly components away from walk areas.
•Do not work alone if potentially hazardous conditions exist.
•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
•Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
Safety with Electricity
•Before beginning any procedures requiring access to the interior of the router, locate the emergency power-off switch for the room in which you are working.
•Disconnect all power and external cables before installing or removing a router.
•Never assume that power has been disconnected from a circuit; always check.
•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
•Never install equipment that appears damaged.
•Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
•If an electrical accident does occur, proceed as follows:
–Use caution; do not become a victim yourself. Disconnect power to the router.
–If possible, send another person to get medical aid; otherwise, assess the condition of the victim and then call for help.
–Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.
In addition, observe the following guidelines when working with any equipment that is disconnected from a power source but still connected to telephone or network wiring:
•Never install telephone wiring during a lightning storm.
•Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
•Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
Preventing Electrostatic Discharge Damage
Many router components can be damaged by static electricity. Some components can be damaged by voltages as low as 30V, while static voltages as high as 35,000V can be generated just by handling plastic or foam packing material, or by sliding assemblies across plastic and carpets. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, observe the following guidelines:
•Always use an ESD-preventive antistatic wrist strap or ankle strap and ensure that it makes good skin contact.
Caution
You should periodically check the resistance value of the ESD-preventive strap. The measurement should be between 1 and 10 megohms.
•When removing or installing a component, make sure the equipment end of your antistatic strap leash is connected to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis. (See Figure 4.) Avoid contact between the component and your clothing. The ESD-preventive wrist strap only protects the component from ESD voltages on the body; ESD voltages on your clothing can still cause component damage.
•Always place a card component-side-up on an antistatic surface, in an antistatic card rack, or in a static shielding bag. If you are returning the item to the factory, immediately place it in a static shielding bag.
•When installing a line card or route processor (RP), use the ejector levers to seat the card connectors in the backplane, then tighten both captive screws on the faceplate of the card. These screws prevent accidental removal, provide proper grounding for the router, and help to ensure that the card connector is seated in the backplane.
•When removing line cards, clock and scheduler cards, switch fabric cards, or an RP, use the ejector levers to unseat the card connector from the backplane. Pull the metal card carrier out slowly, placing one hand along the bottom of the carrier to guide it straight out of the slot.
•Handle line cards, clock and scheduler cards, switch fabric cards, or an RP by the metal card carrier edges only; avoid touching the board or any connector pins.
