ATTENTION ! Prior to servicing a product, management server, or

Installation of products and servers on a public customer intranet can
complicate problem determination and fault isolation.
ATTENTION ! Activating a preferred path can result in receipt of out-of-
order frames if the preferred path differs from the current path, if input and
output (I/O) is active from the source port, and if congestions is present on
the current path.
ATTENTION ! Do not remove a power supply unless a replacement FRU is
immediately available. To avoid product overheating, a removed power
supply must be replaced within five minutes.
