7.6.1 Replacing an MPO-4*DLC Optical Fiber (for 8 Gbit/s
Fibre Channel Interface Module (Eight Ports)/16 Gbit/s Fibre
Channel Interface Module (Eight Ports))
This section describes how to replace an MPO-4*DLC optical fiber.
Impact on the System
During the replacement of an MPO-4*DLC optical fiber, the system switches
services from the fibers (four array ports) to other ports on this controller or on
the peer controller. If available links are unable to bear the current service load,
host latency increases and the system performance degrades. If there are no
redundant links, services carried by the optical fiber will be interrupted.
