It is not necessary to power down the system.
1. Remove the failed Fibre Channel cable from the GBICs at both ends. If
a replacement cable cannot be connected to the GBICs immediately,
insert dust plug covers into the GBICs to protect them from
contamination.
2. Remove the protectors from the replacement Fibre Channel cable.
3. Insert the cable connectors into the GBIC modules.
The power supply in the RA4000 is hot-pluggable if a redundant power supply
is installed. The power supply can be easily replaced by simply unplugging the
failed power supply, removing it, and plugging in a replacement. The second

Single and redundant systems are described in the following two sections.
Follow the procedure that applies to your system.
