System Software; Jumpers; Leds; Serial Ports - Cisco 7000 Series Hardware Installation And Maintenance Manual

System Software

The Cisco 7000 series routers support downloadable system software and microcode for most Cisco
IOS and microcode upgrades, which enables you to remotely download, store, and boot from a new
image. Flash memory contains the default system software. An erasable programmable read-only
memory (EPROM) device contains the latest microcode version, in compressed form, for each
interface processor. At system startup, an internal system utility scans for compatibility problems
between the installed interface processor types and the bundled microcode images, then
decompresses the images into running dynamic random-access memory (DRAM). The bundled
microcode images then function the same as the EPROM images.

Jumpers

There are no user-configurable jumpers on the RSP7000.

LEDs

The two LEDs on the RSP7000 indicate the system and RSP7000 status. The normal LED is on
when the system is operational. During normal operation, the CPU halt LED should be off. The CPU
halt LED goes on only if the system detects a processor hardware failure.

Serial Ports

Two asynchronous serial ports on the RSP7000, the console and auxiliary ports, allow you to connect
external devices to monitor and manage the system. The console port is an Electronic Industries
Association/Telecommunications Industry Association (EIA/TIA)-232 receptacle (female) that
provides a data circuit-terminating equipment (DCE) interface for connecting a console terminal.
Note
standard by the Electronic Industries Association (EIA) and Telecommunications Industry
Association (TIA).
The auxiliary port is an EIA/TIA-232 plug (male) that provides a data terminal equipment (DTE)
interface; the auxiliary port supports flow control and is often used to connect a modem, a channel
service unit (CSU), or other optional equipment for Telnet management.

7000 Series Chassis Interface (RSP7000CI)

The RSP7000CI, shown in Figure 1-11, works with the RSP7000, and consists of a printed circuit
board attached to a metal carrier. The RSP7000CI has no user-configurable jumpers or switches, and
its faceplate contains no LEDs. The RSP7000CI is distinguishable only by the label on its faceplate,
which reads 7000 Series Chassis Interface. (See Figure 1-11.) The RSP7000CI provides the
environmental monitoring and power supply monitoring functions for the Cisco 7000 series chassis.
The RSP7000CI isolates the CPU and system software from chassis-specific variations.
Caution
ON to the chassis. The RSP7000CI does not support online insertion and removal (OIR). You must
install the RSP7000CI in the 7000 CI slot (slot 4 in the Cisco 7010).
EIA/TIA-232 was known as recommended standard RS-232 before its acceptance as a
To prevent system problems, the RSP7000CI must not be removed or installed with power
