Switch status policy planning

Fabric Watch monitors the health of the switch under various classes.
overall switch status policy parameters in a switch and identifies the factors that affect their health.
Note that not all switches use the listed monitors.
Use the switchstatusPolicySet command to manually change the policy setting. Refer to the FOS
Command Reference Manual for more information.
NOTE
The default setting for a MARGINAL state is 0, which prevents Fabric Watch from generating
notifications due to missing power supplies. For configurations with a 2+2 power suppy
combination, we recommend you change the default Fabric Watch default setting of 0 to 2 power
supplies (PS), which forces the overall switch status to a MARGINAL state.
Brocade DCX 8510-8 default policy
The default Fabric Watch policy for the Brocade DCX 8510-8 with total power consumption of more
than 2000w does not properly reflect the switch status on the power supply. Fabric Watch users
must manually update their default configuration for the minimum number of power supplies to
three if they have installed more than 256 ports in an 8510-8 chassis.
NOTE
The presence of four or more FS8-18 encryption blades in the DCX Data Center Backbone causes
the Fabric Watch switch status policy for power supplies to assume a policy setting of 2,1.
Brocade 6505 default policy
The default Fabric Watch policy for the Brocade 6505 is one power supply in the left bay with an
optional configuration of two power supplies in both the left and right bay. The default configuration
for the Brocade 6505 is a 2 (DOWN) and 0 (MARGINAL), corresponding to a one power supply
configuration. If converting to a two power supply configuration, use the switchstatusPolicySet
command to manually change the configuration to 2,1 for the power supply and Fan FRU units. If
converting back to a one power supply configuration, use the switchstatusPolicySet command to
manually change the power supply and Fan FRU units to 1,0.

Health factors
Power supply thresholds detect absent or failed power supplies, and power supplies that are
not in the correct slot for redundancy.
Temperature thresholds, faulty temperature sensors.
Fan thresholds, faulty fans.
Faulty WWN card (applies to modular switches).
Switch does not have a redundant CP (applies to modular switches).
Faulty blades (applies to modular switches).
Faulty core blades.
