9 Chapter 1: General information
— Duplicate domain IDs - One or more domain ID conflicts are
detected.
— Incompatible zoning configurations - zoning configurations
for the switches are not compatible.
— Build fabric protocol error - A protocol error is detected
during the process of forming the fabric.
— No principal switch - No switch in the fabric is capable of
becoming the principal switch.
NOTE: At least one director or switch in a multiswitch fabric must be set to
either principal or default, making it capable of becoming principal switch. If
all directors and switches are set to never principal, all ISLs will segment
(Reason code 05).
— Unresponsive switch - Each switch in a fabric periodically
verifies operation of all attached switches. An ISL segments if
the attached switch does not respond to a verification request.
— ELP retransmission failure timeout - A switch that exhibits a
hardware failure or connectivity problem cannot transmit or
receive Class F frames. The director did not receive a response
to multiple exchange link protocol (ELP) frames, did not
receive a fabric login (FLOGI) frame, and cannot join an
operational fabric.

This section lists the physical characteristics, storage and shipping
environment, operating environment, and service clearances for the
