5.4Switch Control Processor Replacement

The following procedure explains how to remove an i960 switch control processor (SCP) from a switch fabric and install a new SCP.

WARNING! It is highly recommended that you use the included grounding strap when handling this or any other component.

CAUTION Do not attempt to remove or replace an SCP without ﬁrst removing all connections to the SCP (i.e., serial or Ethernet connections).

1.Loosen the two captive fasteners on either edge of the SCP using a straight screwdriver.

2.Pull ﬁrmly and carefully on the two captive fasteners, removing the SCP from the switch fabric as shown in Figure 3.5.

For example, an OC-3c network module that is removed from slot A of the old switch fabric must be installed in slot A of the new switch fabric. Therefore, it is recommended that you label all network connections and network modules before removing them Hardware Maintenance Procedures 5-17CAUTION Make sure the replacement board is properly aligned in the slot in the next step Hardware Maintenance Procedures 5-18 CHAPTER Software Upgrade Instructionseject device 6.1 Obtaining the Software Upgrade File via DisketteSoftware Upgrade Instructions tar -xvf deviceSoftware Upgrade Instructions foreextract deviceoperation upgrade ? 6.2 Performing the Software Upgrademkdir /tftpboot mv ﬁlename /tftpbootoperation upgrade 169.144.3.54ASX-200BX4.0.01.3 operation upgrade 169.144.3.54asx-scp4.0.01.3Software Upgrade Instructions Reboot the switchy? y Software Upgrade InstructionsSoftware Upgrade Instructions 6.3 Changing between Multiple Versions of Softwarelocalhostoperation reboot Software Upgrade InstructionsAre you sure you want to reboot this switch n? y Software Upgrade Instructions 6.4 Using bootp to Download Software to the Switch6.4.2 Setting Up Your bootp Server 6.4.1 Overview6-10 6.4.3 Adding an Entry for Your Switch in the bootptab FileSoftware Upgrade Instructions Software Upgrade Instructions 6-11The variables in the previous example are deﬁned as follows 6-12 6.4.4 Setting Up a tftpboot ServerSoftware Upgrade Instructions A.1 Adapter Hardware Troubleshooting TroubleshootingAPPENDIX A Figure A.1 -
