Control processor blade (CP8)
This section describes how to remove and replace a control processor (CP8) blade. Each DC Director has
two CP8 blades located in slot 6 and slot 7.

the new blade to the active CP blade’s firmware version.
The replacement procedure for the CP blade takes approximately 30 minutes. The following items are
required for the CP blade replacement:
• ESD grounding strap
• Workstation computer
• Serial cable
• IP address of an FTP server for backing up the DC Director configuration
• Phillips #2 screwdriver
• Replacement CP blade. Requires the DC Director CP blade (CP8).
