When you press and hold the alarm control switch for at least 5 seconds you clear all the
fault codes.
NOTE
The alarm control switch does not affect either the error
condition or the error code. Only correcting the error
condition will clear the error code.
During a controlled power shut down, the alarm control switch functions as an enclosure
power switch. When a controlled power shut down is in affect, you must press the alarm
control switch to restore dc power to the enclosure.
3.2 Setting the PVA Addresses
The front panel of the PVA module is shown in Figure 3–1. Compaq supports enclosure
addresses 2 and 3, only for expansion enclosures. Figure 3–2 defines the SBB device IDs
for these two settings of the PVA SCSI bus address switch. The use of these addresses in
combination depends on the number of enclosures and possible addressing conflicts.
CAUTION
Compaq does not support any enclosure address
combination not listed in Table 3–4.
