Q.
How is the switch designed for high availability?
A.
The switch is designed as follows for high availability:
•
Power system
—2+2 redundancy on an S7504E-XS switch and 1+1 redundancy on other S7500E-XS
switches.
•
Power modules and fan
trays
—Field replaceable.
•
Software
—Failure locating, detection, and isolation.
All module designs are verified in environment simulation tests and HALTs.
