Leds; Serial Ports; 7000 Series Route Switch Processor (Rsp7000) - Cisco 7000 Hardware Installation And Maintenance

Jumper J2, which is located near the configuration register, provides write protection for Flash
memory. (See Figure 1-8.) The jumper is installed on J2 by default, which allows you to write to
Flash memory. When the jumper is removed, Flash memory is read-only; you cannot write to Flash
memory or erase the contents until you replace the jumper.
Jumpers J3 and J4 are set according to the size of the eight system software EPROMs. You need to
reset these jumpers only if you upgrade the system software by replacing the EPROMs instead of
downloading the new image, and if the size (capacity) of the new EPROMs is greater than those you
replace.
For a detailed description of all jumper functions and settings, refer to the section "RP and RSP7000
Configurations" in the chapter "Maintenance."

LEDs

The three LEDs on the RP indicate the system and RP status. The chassis front panel normal LED
and the RP normal LED are both controlled by the RP and light to indicate that the system is
operational. During normal operation, the CPU halt and boot error LEDs on the RP should be off.
When the system is turned on or restarted, the boot LED goes on for 1 or 2 seconds, then goes off.
The CPU halt LED, which lights only if the system detects a processor hardware failure, should
never be on. For complete descriptions of the LED states, refer to the "Reading LED Indicators"
appendix.

Serial Ports

Two asynchronous serial ports on the RP, the console and auxiliary ports, provide the means for
connecting a terminal, modem, or other device for configuring and managing the system. A data
circuit-terminating equipment (DCE) EIA/TIA-232 receptacle console port on the RP provides a
direct connection for a console terminal. The adjacent data terminal equipment (DTE) EIA/TIA-232
plug 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 of the attached device.
Note
Industry Association (TIA) as a standard, EIA/TIA-232 [or 449] was an EIA recommended standard
(RS) known as RS-232 [or 449].
The two EIA/TIA-232 serial ports on the RP, console and auxiliary, support asynchronous
transmission. Asynchronous transmission uses control bits to indicate the beginning and end of
characters, rather than precise timing. The serial interface ports on the FSIP support synchronous
transmission, which maintains precise clocking between the transmitter and receiver by sending
frames of information that comprise separate clock signals along with the data signals. When
connecting serial devices, ensure that the devices support the proper transmission timing methods
for the respective port: asynchronous for the console and auxiliary ports, and synchronous for the
FSIP serial ports.

7000 Series Route Switch Processor (RSP7000)

The RSP7000 is a new main system processor module for the Cisco 7000 series routers. The
RSP7000 combines all of the switched routing and high-speed switching functions of the separate
Route Processor (RP) and Switch Processor (SP), which are used in the Cisco 7000 series routers,
