Product Overview Before replacing the card cage and backplane assembly, read the “Safety Guidelines” Caution section on page 7. The speciﬁc procedures for removing and installing the card cage and backplane assembly might require two people to perform. Product Overview The Cisco 7513, Cisco 7513-MX, and Cisco 7576 card cage holds the processor modules used by the system.

Product Overview To provide a viewable image, slot numbers 0, 1, 2, 11, and 12 are not shown in Figure 2. The Note slot numbering scheme uses color coding to assist in identifying routers and CyBus assignments. Refer to the “Identifying Cisco 7576 Independent Routers and CyBuses” section in the Cisco 7500 Series Installation and Conﬁguration Guide for detailed information on the slot numbering scheme.
Figure 4 shows the location of the Cisco 7576 dual arbiters and chassis interfaces on the rear of the backplane. Figure 4 Dual arbiters Chassis interfaces When you view the rear of the card cage, the dual arbiter and chassis interface on the right Note side are used with router A, and the dual arbiter and chassis interface on the left side are used with router B.
Installation Safety, ESD Precautions, and Tools Required Safety Warnings Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may harm you. A warning symbol precedes each warning statement. This warning symbol means danger. You are in a situation that could cause bodily Warning injury.
Este símbolo de aviso indica perigo. Encontra-se numa situação que lhe poderá causar danos Aviso físicos. Antes de começar a trabalhar com qualquer equipamento, familiarize-se com os perigos relacionados com circuitos eléctricos, e com quaisquer práticas comuns que possam prevenir possíveis acidentes.
Installation Safety, ESD Precautions, and Tools Required In addition, use the guidelines that follow when working with any equipment that is connected to telephone wiring or other network cabling: • Never install telephone wiring during a lightning storm. • Never install telephone jacks in wet locations unless the jack is speciﬁcally designed for wet locations.
Removing and Replacing Processor Modules Before you can replace the card cage and backplane assembly, you need to remove all processor modules installed in the card cage, and then replace them after the new card cage assembly is in place. The term processor module refers to the RSP2, RSP4, or RSP8 and all interface processors. Note Always use the ejector levers when installing or removing processor modules.

Figure 6 Caution To prevent damage to the processor modules, do not stack them on top of each other. Replacing Processor Modules You can replace an interface processor in any of the 11 interface processor slots, 0 through 5, and 8 through 12, from left to right.
Removing Power Supplies Always install blank processor module ﬁllers in empty processor slots to maintain the Caution proper ﬂow of cooling air through the chassis. Use a screwdriver to tighten both captive installation screws on each processor module. Step 7 Attach network interface cables or other devices to the interface ports.
Disconnect the power supply cables from the power supplies. Step 2 • For DC-input power supplies, refer to the conﬁguration note 1200-Watt DC-Input Power Supply Replacement Instructions (Publication Number 78-1899-xx) that shipped with your Cisco 7513, Cisco 7513-MX, or Cisco 7576 chassis equipped with DC-input power supplies.
Removing the Old Card Cage and Backplane Assembly To maintain agency compliance requirements and meet electromagnetic interference Caution (EMI) emissions standards in a Cisco 7513 or Cisco 7576 chassis with a single power supply, the power supply blank must remain in the power supply bay adjacent to the power supply. (See Figure 10.) Replace this blank in the chassis after you replace the card cage assembly.
To remove the card cage and backplane assembly, follow these steps: Turn the power switch on each power supply to the off position (O). Step 1 Step 2 Disconnect the power supplies. • For DC-input power supplies, refer to the conﬁguration note 1200-Watt DC-Input Power Supply Replacement Instructions (Publication Number 78-1899-xx) that shipped with your Cisco 7513, Cisco 7513-MX, or Cisco 7576 chassis equipped with DC-input power supplies.
Exchanging the EEPROM Devices Figure 11 Captive screw Card cage side flange Captive screw Air intake grill With the captive screws loosened, carefully pull the card cage and backplane assembly Step 6 straight out of the chassis until the entire assembly is clear of the chassis sides. (See Figure 11.) The assembly is not heavy but might be awkward to handle.
The new EEPROM device(s) that shipped on your new card cage are blank. Caution Do not perform these steps if you are upgrading a Cisco 7513 to a Cisco 7576. These Note instructions apply only to the replacement of an equivalent card cage. The following procedure requires you to ﬁrst exchange the blank EEPROM device(s) on your new card cage for the old EEPROM device(s) from your old card cage, and then place the blank EEPROM device(s) on your old card cage for return to Cisco.
Installing the New Card Cage and Backplane Assembly Figure 13 Chassis interface board B Note router A and router B. The backplane of the Cisco 7576 includes two dual arbiters, two chassis interfaces, and two EEPROM devices. Figure 13 shows the speciﬁc location and designation of each EEPROM device.
Figure 14 Replacing the Card Cage and Backplane Assembly Captive screw Card cage side flange Captive screw Air intake grill POW ER Caution The electronic components on the rear of the backplane are completely exposed when the card cage and backplane assembly is removed from the chassis. To prevent damaging these components, carefully slide the assembly into the chassis opening.
Replacing Power Supplies Replacing Power Supplies To replace the power supply, follow these steps: To replace a power supply, hold it as shown in Figure 15 and slide it into the power supply Step 1 bay. Push the supply all the way into the chassis until the sides are ﬂush against the chassis frame.
Repeat Step 1 through Step 3 for the second power supply if one is installed, or Step 1 Step 4 and Step 2 for the power supply blank if one is present. Note supply, reconnect the power cable at the power source. This completes the power supply replacement procedure.
