Finding the Correct Boot Sequence
The correct boot sequence depends on the particular configuration, but the hosts
should usually be booted last. Following are boot sequences that may be tried if
problems are occurring.
Checking the Simple Name Server (SNS)
When the Vixel 9000 Series Switch is running in Fabric Mode or Fabric (Public/
Private) Mode, each connected device logs into the Simple Name Server (SNS) with
identifying information, including its supported protocol (FC-4 Type). You can view
the SNS table to verify that a particular device logged in with the correct FC-4 type.
The SNS table is available through the switch’s Command Line Interface (CLI) and
Web Manager.
To view the SNS table through the CLI, go to the root menu and type: show sns
To view the SNS table through the Web Manager, click Statistics and then click SNS
on the left side menu.

• Make sure the cable used is appropriate
for the transceiver used.
• Make sure that the receive and transmit
ends of the optical cable are correctly
polarized (crossed) into their respective
receive and transmit receptacles, both on
the device end and the switch end.
(Optical cables are not automatically
polarized as copper cables are.) Note: If
the receive and transmit receptacles are
not marked or indicated by bracket
enclosures, cross the printed side of the
wiring with the unprinted side. For
example, at the receive socket in the
device end, plug in the printed side of the
wiring; at the receive socket in the switch
end, plug in the unprinted side of the
wiring.
