Fsip Configurations - Cisco 7000 Hardware Installation And Maintenance

This completes the SIMM replacement procedure.
Proceed to the section "Removing and Replacing the RP, SP or SSP, RSP7000, or RSP7000CI" to
replace the RSP7000 in the chassis and restart the system for an installation check. Note that the
RSP7000 does not support OIR
If the system fails to boot properly, or if the console terminal displays a checksum or memory error,
check the following:
•
Ensure that all SIMMs are installed correctly. If necessary, shut down the system and remove the
RSP7000. Check the SIMMs by looking straight down on them and then inspecting them at eye
level. The SIMMs should all be aligned at the same angle and the same height when properly
installed. If a SIMM appears to stick out or rest in the socket at a different angle from the others,
remove the SIMM and reinsert it. Then replace the RSP7000 and reboot the system for another
installation check.
•
Each DRAM SIMM bank must contain SIMMs of the same size and speed or the system will not
operate. SIMMs must be 60 ns or faster. The speed is printed along one edge of the SIMM.
If after several attempts the system fails to restart properly, contact a service representative for
assistance. Before you call, make note of any error messages, unusual LED states, or any other
indications that might help solve the problem.
Note
Routers with 128 MB of DRAM will take longer to boot than those with 16 MB of DRAM.

FSIP Configurations

The FSIP supports EIA/TIA-232, EIA/TIA-449, V.35, and X.21 electrical interfaces in both DTE
and DCE mode, and EIA-530 interfaces in DTE mode. The port adapter cable connected to each port
determines the electrical interface type and mode of the port. To change the electrical interface type
or mode of a port, you replace the port adapter cable and use software commands to reconfigure the
port for the new interface. At system startup or restart, the FSIP polls the interfaces and determines
the electrical interface type of each port (according to the type of port adapter cable attached).
However, it does not necessarily repoll an interface when you change the adapter cable online. To
ensure that the system recognizes the new interface type, you must shut down and reenable the
interface after changing the cable. When setting up a new DCE interface or changing the mode of an
interface from DTE to DCE, or when setting up a loopback test, you must also set the clock rate on
the interface. If necessary, you can also use software commands to invert the clock to compensate
for phase shifts caused by circuit delays or variances in cable lengths.
The default configuration for serial ports is DCE mode, NRZ format, and 16-bit CRC error
correction. All serial interfaces support nonreturn to zero inverted (NRZI) format and 32-bit error
correction, both of which are enabled with a software command.
Note
need when installing or changing the configuration of serial interface ports. For complete command
descriptions and instructions, refer to the related software documentation on UniverCD or printed
manuals.
The time required for the system to initialize varies with different router configurations.
