Interface Processor Installation Procedures
• Using the handle to force the interface processor all the way into the slot can pop the ejector levers
out of their springs. If you then try to use the ejector levers to seat the interface processor, the first
layer of pins (which are already mated to the backplane) can disconnect and then remate with the
backplane, which the system interprets as a board failure.
• Using the handle to force or slam the interface processor all the way into the slot can also damage
the pins on the board connectors if they are not aligned properly with the backplane.
• When using the handle (rather than the ejector levers) to seat the interface processor in the
backplane, you might need to pull the interface processor back out and push it in again to align it
properly.
Even if the connector pins are not damaged, the pins mating with and disconnecting from the
backplane will cause the system to interpret a board failure. Using the ejector levers ensures that the
board connector mates with the backplane in one continuous movement.
• Using the handle to insert or remove an interface processor, or failing to push the ejector levers to
the full parallel position, can leave some (not all) of the connector pins mated to the backplane, a
state that will hang the system. Using the ejector levers and making sure that they are pushed fully
into position ensures that all three layers of pins are mated with (or free from) the backplane.
It is also important to use the ejector levers when removing an interface processor to ensure that the
board connector pins disconnect from the backplane in the logical sequence expected by the system. Any
processor module (interface processor or RSP) that is only partially connected to the backplane can hang
the bus. (Detailed steps for correctly installing and removing an interface processor follow in the
“Interface Processor Installation Procedures” section on page 22.)
For additional information, refer to the installation and configuration guide for your interface processor
available online at http://www.cisco.com/univercd/cc/td/doc/product/core/cis7505/interpro/index.htm,
on the Documentation CD-ROM, or as printed documents. Refer to the Cisco 7500 Series Router
Documentation flyer (part number DOC-7812955) that shipped with your interface processor, or view it
at http://www.cisco.com/univercd/cc/td/doc/product/core/cis7505/12955fly.htm.
Interface Processor Installation Procedures
The following sections describe the procedures for removing or installing an interface processor. (See
the “Guidelines for Interface Processor Removal and Installation” section on page 21 before removing
an interface processor while power to the system is on.)
Caution To avoid erroneous failure messages, remove or insert only one interface processor at a time. Also,
after inserting or removing an interface processor, allow at least 15 seconds before removing or
inserting another interface processor so that the system can reinitialize and note the current
configuration of all interfaces.
Note If you install or remove other interface processors in a Cisco 7000 series or Cisco 7500 series router
with a CT3IP installed, you might have to reboot the system after the removal and replacement of
that interface processor. (In general, and to prevent system problems, we recommend you follow the
procedures described in this section and the guidelines described in the “Guidelines for Interface
Processor Removal and Installation” section on page 21.)
