Second-Generation Channel Interface Processor (CIP2) Installation and Configuration 13
CIP2 Installation Prerequisites
• When you remove a processor module, place it card side up on an antistatic surface or in a static
shielding bag. Immediately place the module in a static shielding bag if you need to return it to
Cisco Systems.
• Avoid contact between electronic equipment and clothing. Antistatic straps only protect the
equipment from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Caution For safety, periodically check the resistance value of the antistatic strap. The
measurement should be between 1 and 10 megohms.
Guidelines for Interface Processor Removal and Installation
This section describes mechanical functions of system components, emphasizes the importance of
following correct procedures to avoid unnecessary board failures, and is for background only;
specific procedures follow in the section “CIP2 Hardware Installation” on page 30.
You can remove and replace interface processors while the system is operating; you do not need to
notify the software or reset the system power. This functionality enables you to add, remove, or
replace interface processors with the system online, which provides a method that is seamless to end
users on the network, maintains all routing information, and ensures session preservation.
After an interface processor is reinstalled, the system brings on line only interfaces that match the
current configuration and were previously configured as up; all others require that you configure
them with the configure command.
Caution The system can indicate a hardware failure if you do not follow proper procedures.
Remove or insert only one interface processor at a time. Allow at least 15 seconds for the system to
complete the preceding tasks before removing or inserting another interface processor. Disrupting
the sequence before the system completes its verification can cause the system to interpret hardware
failures.
All interface processors have ejector levers that allow you to firmly seat an interface processor in the
interface processor slot. The function of the ejector levers is to align and seat the card connectors in
the backplane.
Caution Always use the ejector levers to remove or install the CIP2. The ejectors help ensure that
backplane connectors on the card are fully seated in, or fully ejected from, the backplane. Failure to
use the ejector levers could result in a partial backplane connection, which can hang the system.
The captive installation screws on the ends of the CIP2 faceplate, when tightened, provide EMI
shielding and also help ensure proper seating in the backplane. After using the ejector levers to
install a CIP2, tighten the captive installation screws to prevent the CIP2 from becoming partially
dislodged from the backplane. These screws must be tightened to meet EMI specifications.
