below the caution threshold. If one or more sensors exceed this threshold, iLO 2 implements the
recovery policy to prevent damage to server components.
• If the temperature exceeds the caution threshold, the fan speed is increased to maximum.
• If the temperature exceeds the critical temperature, a graceful server shutdown is attempted.
• If the temperature exceeds the fatal threshold, the server is immediately turned off to prevent
permanent damage.
Monitoring policies differ depending on server requirements. Policies usually include increasing
fan speed to maximum cooling, logging the temperature event in the IML log, providing visual
indication of the event using LED indicators, and starting a graceful shutdown of the operating
system to avoid data corruption.
After correcting the excessive temperature conditions additional polices are implemented including
returning the fan speed to normal, recording the event in the IML, turning off the LED indicators,
and if appropriate, canceling shutdowns in progress.
Power
The VRMs/Power Supplies tab displays the state of each VRM or power supply. VRMs are required
for each processor in the system. VRMs adjust the power to meet the needs of the processor
supported. A VRM can be replaced if it fails. A failed VRM prevents the processor from being
supported.
iLO 2 also monitors power supplies in the system to ensure the longest available uptime of the
server and operating system. Power supplies can be affected by the brownouts and other electrical
conditions, or AC cords can be accidentally unplugged. These conditions result in a loss of
redundancy if redundant power supplies are configured, or result in loss of operation if redundant
power supplies are not in use. Additionally, if a power supply failure is detected (hardware failure)
or the AC power cord is disconnected, then these events are recorded in the IML and the LED
indicators light.
iLO 2 monitors power supplies to ensure that they are correctly installed. This information appears
on the System Information page. Reviewing the System Information page and IML will assist you
in deciding when to repair or replace a power supply, preventing a disruption in service.
Processors
The Processors tab displays the available processor slots, the type of processor installed in the slot,
and a brief status summary of the processor subsystem. If available, installed processor speed in
MHz and cache capabilities are displayed.
Memory
The Memory tab displays the available memory slots and the type of memory, if any, installed in
the slot.
NIC
The NIC tab displays the MAC addresses of the integrated NICs. This page does not display add-in
network adapters.
iLO 2 Log
The iLO 2 Log page displays the iLO 2 Event Log, which is a record of significant events detected
by iLO 2. Logged events include major server events such as a server power outage or a server
reset and iLO 2 events such as unauthorized login attempts. Other logged events include successful
or unsuccessful browser and Remote Console logins, virtual power and power cycle events, clear
event log actions, and some configuration changes, such as creating or deleting a user.
iLO 2 provides secure password encryption, tracking all login attempts and maintaining a record
of all login failures. Authentication Failure Logging allows you to configure logging criteria for
