30 Second-Generation Channel Interface Processor (CIP2) Installation and Conﬁguration

CIP2 Hardware Installation

Caution To prevent damaging the PCA connector on the CIP2 by unintentionally disconnecting the

Y cable from the PCA connector, provide adequate strain relief for the heavy bus and tag cables that

attach to the PCA.

CIP2 Hardware Installation

The following sections describe the procedures for installing or replacing the CIP2:

• Removing a CIP2 or an Interface Processor Filler, page 31

• Installing a CIP2, page 34

• Attaching the CIP2 to the Channel, page 35

Caution To avoid unnecessary errors, read the section “Guidelines for Interface Processor Removal

and Installation” before removing or replacing a CIP2.

Before installing a newCIP2, ensure that your system meets the minimum software and microcode

requirements described in the sections “CIP2 Software, Hardware, and Microcode Prerequisites,” on

page 4, and “CIP2 Microcode Overview” on page 6.

While you can remove and install a CIP2 without turning off system power, we do recommend that

you administratively shut down CIP2 interface before insertion and removal. In any case, you must

follow the insertion instructions carefully; for example, failure to use the ejector levers or insert the

CIP2 properly can cause system error messages indicating a card failure.

Each unused interface processor slot contains an interface processor ﬁller (which is an interface

processor carrier without an interface card) to keep dust out of the chassis and to maintain proper

airﬂow through the interface processor compartment.

If you install a new CIP2, select an empty interface processor slot and remove the interface processor

ﬁller. If you replace a CIP2, you can retain the existing interface conﬁguration by removing the

existing interface processor and installing the new one in the same slot; however, the new CIP2 must

have the same channel adapter conﬁguration as the CIP2 you replaced.

Proceed to the section “Removing a CIP2 or an Interface Processor Filler,” on page 31, for

instructions on making an interface processor slot available for the new CIP2, then to the section

“Installing a CIP2,” on page 34, for the installation instructions. After the new CIP2 is secure, follow

the procedures in the section “Checking the CIP2 Installation,” on page 40, to verify that it is

installed and functioning properly.
