If everything matched properly (as they would from the factory), the output of the “show system fans” would
simply be as follows, with no warnings or messages:
ProCurve Switch 6600ml-24G# sh system fans
Fan Information:
Num State AirowDirection Failures
Sys-1 Fan Ok Power To Port 0
ProCurve Switch 6600ml-24G# sh system fan-pref-airow-dir
 Preferredfanairowdirection:PowerToPort
Imagine if someone wanted their ports mounted in the front/cold aisle and they had a warranty replacement of
the fan tray—and they forgot to reverse the fans. This event would pop up because the user had configured the
6600 switch with a power-to-port direction (that is, the air is pulled from the back of the unit [the power] and
ejected out of the front [the ports]). In this instance, the user would receive a warning.
The SNMP MIB object to manipulate the setting of the “Preferred Fan Direction” is:
hpicfDcFan.mib –> hpicfFanUserPrefAirflowDir
6600 LEDs
The LEDs on the 6600 switch are grouped in two columns.
•One set to indicate the status of system components (power supplies, temperature, fan tray, and so on)
•One set to indicate the switch state (Active, Standby, or Down)
Locator LED
The Locator function is enabled through the following CLI command:
ProCurve Switch 6600ml-24G# chassislocate ?
 blink Blinkthechassislocateled(default30minutes).
 off Turnthechassislocateledoff.
 on Turnthechassislocateledon(default30minutes).
ProCurve Switch 6600ml-24G# chassislocate blink ?
 <1-1440> Numberofminutesduration(default30).
<cr>
By indicating a number N after either the “blink” or “on” parameter, the locator LED will extinguish
automatically after N minutes. Without specifying a value, the default is 30 minutes.
The LED indicators are covered in more detail in “Appendix G: troubleshooting” later in this document.
