Redundant Power Supplies
The VSU-10000 includes redundant power supply modules. If one fails, the
second power supply instantly takes over, without disrupting the operation of the
unit. Concurrently, an audible alarm sounds, the green status LED indicator on
the power supply subsystem goes off.
The power supply modules are hot-swappable and can be replaced without
interrupting services by powering down the defective module. Refer to
Chapter 4, Troubleshooting, for instructions on replacing a defective power
supply module.
Dual Cooling Fans
System reliability is increased by hardware redundancy of the main cooling
system, so a failure of either fan does not prevent the safe operation of the unit. If
the fan speed falls below the threshold value, a warning message is sent to the
console port, an SNMP trap and a syslog message are sent to all configured
SNMP trap targets and configured syslog server targets respectively (e.g., the
workstation on which the VPNmanager resides, a third-party network
management station like HPOpenView, or Unix-based syslog server).
