- Page 2 The Cisco 7010 provides three interface slots, and offers the same performance as the Cisco 7000. Figure 2 shows the interface processor end of the Cisco 7000 model, which provides access to the seven processor slots and the removable power supplies. When facing the interface processor end of the chassis, the RP and SP slot are on the far right.
- Page 3 Figure 3 shows the interface processor end of the Cisco 7010 model, which provides access to the five processor slots, the AC input receptacle, the power switch, and a power status indicator. When facing the interface processor end of the chassis, the RP and SP slots are at the top. The three interface processor slots are numbered from the bottom up beginning with slot 0 (the bottom slot) through slot 2 (the center slot).

Page 6: Tools And Parts Required
Prerequisites Prerequisites Before you begin the installation of the SSP, review the tools and parts required, and the safety and ESD-prevention guidelines in this section. Tools and Parts Required You need some or all of the following tools and parts to perform the following procedures. Before you begin, read the entire procedure to determine which tools you need for the installation or upgrade you will perform. - Page 7 Prerequisites Preventing Electrostatic Discharge (ESD) Damage Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. The SSP comprises a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier.
- Page 8 (Cisco IOS) Release 10.0, or later. • The SSP with 2 MB of packet memory requires Cisco IOS Release 10.0(11) or later. Cisco IOS Releases 10.2(7) or later, 10.3(4) or later, and 11.0(1) or later, will provide the best use of the 2-MB SSP.

- Page 16 Installing the SSP Replacing an SSP in the Chassis Ensure that all power supplies are turned OFF (O) before installing the SSP in the chassis. The SSP, RP, and interface processors are all keyed for installation only in the correct slot. (Refer to “SSP Description.”) Install the SSP in the SP slot (see Figure 2 and Figure 3), as follows: Caution Handle the SSP by the handle and carrier edges only to prevent ESD damage.

Page 18: Troubleshooting The Installation
System Power LEDs Cisco 7000 series models have a system power LED that should go on and stay on when the system power is turned on. If the LED does not go on or stay on, there is most likely a problem with the input power or one of the internal DC lines. - Page 19 During normal operation, the CPU halt and boot error LEDs are off, and the normal LED is on. Figure 8 RP LEDs (Horizontal Cisco 7010 Orientation Shown) Silicon Switch Processor (SSP) Installation and Configuration...
- Page 20 By checking the state of the LEDs, you can determine when and where the system failed in the startup sequence. The Cisco 7000 features redundant LEDs on the front of the chassis for the RP normal system status LED and the power LEDs on the power supplies. However, because the states reported by these LEDs are also indicated at the interface processor end of the chassis, these LEDs are ignored in the following procedure.
- Page 21 Installing the SSP When you restart up the system, the system power LEDs (DC OK on the Cisco 7010, and AC power on the Cisco 7000) should indicate the following: The DC OK (Cisco 7010) or power (Cisco 7000) LED goes on. The DC fail LED on the Cisco 7000 power supply remains off.
