Decode a fan failure error message. 

Error message:
" SIM[]: bootos.c() % Fan has failed." 

If a SecureStack cooling fan fails, the condition is reported in the syslog, logging buffer, serial console, and current.log (10819).
It is also reported as a generic fanFail trap (13323). 

With lower firmware (C3/B3 f/w and lower, C2 f/w and lower, B2 f/w and lower, A2 f/w all) 

Here is an example of such an error message:

<162> MAR 20 15:00:36 SIM[243378128]: bootos.c(1515) 298 %%
Fan 2 has failed.

The failing stack unit number is represented by the last digit of the '<IP_address>-x' string (unit 5, in this case), and the failed fan instance on that unit is represented by the 'Fan x' designation (instance 2, in this case). 

For this example; stack unit 5 (5780), fan instance 2 (10819) has failed. 

With higher firmware (C3/B3 f/w and higher, C2 f/w and higher, B2 f/w and higher) 

Here is an example of such an error message:

<162> Aug 30 05:35:48 SIM[204096992]: edb_bxs.c(1230) 571 %%
Unit 3: Fan 1 has failed.

The stack unit number of the manager unit issuing the message is represented by the last digit of the '<IP_address>-x' string (unit 1, in this case), and the failing stack unit number and failed fan instance (unit 3's fan 1, in this case) are both now explicitly stated.
