Replacing a GRP
The following sections describe the procedures for replacing a GRP in your system.
Before beginning the procedures, verify that your system meets the minimum requirements as described in the “Preparing for Installation” section on page 10.
When your system meets minimum requirements, proceed to the “Removing a GRP” section on page 14 for instructions on removing the GRP, and then to the “Installing a GRP” section on page 17 for reinstallation instructions.
Caution We recommend that you do not remove a GRP while the system is operating. Removing the installed GRP from a system while the system is operating will cause the system to stop forwarding packets and might cause the system to cease network operation.
Removing a GRP
When you remove a GRP from a slot, be sure to use the ejector levers, which help to ensure that the GRP is fully dislodged from the backplane connector. (See Figure 3.)
