Line Cards The Cisco 12012 is shipped from the factory with up to 11 installed line cards that provide a variety of network media types (based on your order). The line cards are installed in slots 0 through 11 in the upper card cage and interface to each other and to the RP through the switch fabric (cards in the lower card cage).
Page 51: Alarm Card
Physical and Functional Overviews Line cards installed in the Cisco 12012 support online insertion and removal (OIR), which means you can remove and replace a line card while the Cisco 12012 remains powered up. Caution To ensure adequate airflow through the upper card cage, empty card slots must have a card blank installed.

Page 53: Switch Fabric
Switch Fabric The heart of the Cisco 12012 is the switch fabric circuity, which provides synchronized gigabit speed interconnections for the line cards and the RP. The switch fabric circuitry is contained on two types of cards, a clock and scheduler card and a switch fabric card, which install in the five slots in the lower card cage.

Page 55 Physical and Functional Overviews Each clock and scheduler card or switch fabric card provides OC-12/STM-4 (622 Mbps) switching bandwidth for the system. By adding three more cards in the lower card cage, the bandwidth is increased to OC-48/STM-16 (2.4 Gbps). Table 1-5 lists the switch fabric bandwidth and the card configurations needed to support the bandwidth.
Page 56: Power Supplies
The power supply bay, located at the bottom of the card cage assembly, can accommodate up to four AC-input power supplies or two dual-width DC-input power supplies. Do not mix power supplies in the Cisco 12012. In multiple power supply system Caution configurations, all power supplies must be of the same type (four AC-input power supplies or two DC-input power supplies).
Page 57: Ac-Input Power Supply
(9.6 cm) wide by 15 inches (38 cm) deep and weighs 18 lb (8.2 kg). (See Figure 1-8.) The Cisco 12012 requires two AC-input power supplies to operate. Installing one or two additional AC-input power supplies provides power supply redundancy and current sharing capability.

Page 73: Lifting Guidelines
Lifting Guidelines A fully configured Cisco 12012 weighs approximately 380 lb (172 kg); it is not intended to be moved frequently. Before you install the router, ensure that your site is properly prepared so you can avoid having to move the Cisco 12012 later to accommodate power sources and network connections.
Page 74: Safety With Electricity
• Always disconnect all external cables before lifting or moving the Cisco 12012. To prevent damage, never attempt to lift or tilt the Cisco 12012 using the handles Caution on the blower modules or on the power supplies. These handles are not designed to support the weight of the Cisco 12012.
Page 75: Preventing Electrostatic Discharge Damage
Safety Recommendations In addition, use the guidelines that follow 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.
Page 76: Laser Safety
1 and 10 megohms. Laser Safety Single-mode style line cards for the Cisco 12012 are equipped with lasers, which emit invisible radiation. Do not stare into open line card ports. Observe the following warning to prevent eye injury.
Page 77: Rack-Mounting Guidelines
Cisco 12012 does not make the rack unstable. Some telco-style racks are also secured to ceiling brackets, if necessary, because of the weight of the equipment in the rack. Make sure that the rack you are installing the Cisco 12012 in is secured to the building structure.
Page 78 When mounting the router in a four-post or telco-style rack, be sure to use all of the screws provided to secure the frame to the rack posts. Figure 2-1 shows the outer dimensions of the Cisco 12012 frame. 2-8 Cisco 12012 Gigabit Switch Router Installation and Configuration Guide...

(If you have not already done this, refer to the sections “Formatting a Flash Memory Card”...
Page 203 Implementing Other Configuration Tasks • The bootable Cisco IOS software image you want to copy to the Flash memory card exists on a TFTP server to which you have access (meaning you know its name and have connectivity to it), and at least one interface is available to access this server To assure access to a TFTP server, you need to configure one interface using the setup command facility.

Running Diagnostics on the Cisco 12012 Field diagnostics are available for the Cisco 12012 GSR to help you isolate faulty hardware to the level of a field-replaceable unit (FRU) without disrupting the operation of the system. After you identify the faulty unit, you can replace it with a spare unit.
Page 232 Diagnostic Test Overview When using Cisco IOS Release 12.0(21)S or 12.0(21)ST, or a later release of 12.0S Note or 12.0ST, the default download method changes from the mbus to the switch fabric. It takes about 1-minute to obtain test results from the switch fabric compared to 15-minutes to obtain test results from the mbus.
Page 233: Using The Diag Command
