Static electricity can damage the chassis and other electronic devices. To avoid damage,
keep static-sensitive devices in their static-protective packages until you are ready to
install them.
CAUTION:
Before plugging a cable into any port, be sure to discharge the voltage stored on the cable
by touching the electrical contacts to ground surface.

Blade replacement task guide
This section contains a guide to more complete, detailed steps in this section for installing or replacing
CP blades when the device is running (hot swap) or must be powered off (cold swap). References are
provided to the more detailed blade removal and installation steps for further information.
Replacing CP blade (hot-swap)
For hot-swap replacement, the chassis continues to operate while a CP blade is being replaced if the
redundant CP blade is active and a failover does not occur. You can prevent failover by entering the
haDisable command. You can replace one blade or both blades one at a time using these steps. Follow all
steps for one blade, and then repeat the same steps to replace the other blade.
1. Prepare for replacing the blade by following all steps under "Preparing for replacement" on page 138.
2. Remove the blade from the slot by following all steps under "Removing a blade" on page 140.
3. Install a new blade into the empty slot by following all steps under "Installing a blade" on page 141.
4. Verify and synchronize firmware on both blades by following all steps under "Verifying and
synchronizing firmware on blades" on page 142.
