If you are using a switch’s SPAN/mirror port, no nTAP is
required. Simply plug any straight-through or Fibre cable
between the SPAN/mirror port and one of the ports on the
Gen2 capture card.
Fibre Channel has auto-negotiation disabled by default. You
must enabled it first, then connect it to the SPAN or mirror
port on your switch.
Now that you have physically connected the cables for the GigaStor,
you must now configure its software. See “Setting the GigaStor’s IP
address” on page 19.
Figure 24 shows the GigaStor cabled to analyze a server. The TAP can
replace the connection between any DCE (Data Circuit-terminating
Equipment) and DTE (Data Terminal Equipment) device or
connection.
