If the HP Server Remote Management Card is installed, this LED displays:
• Green (Steady): Normal operation. If two power supplies are installed, it indicates
redundancy.
• Red (blinking at 2 Hz blink rate): A subsystem has a critical problem preventing the
server from powering on.
• Amber (blinking 1 Hz blink rate): The power subsystem has lost redundancy since
the last boot, or a fan has failed in a power supply. Please see LED’s on power
supplies for further diagnosis (See Power Supply Indicator)
If the HP Server Remote Management Card is not installed, the LED behavior
observes the following changes:
• It does not indicate Predictive Failure; it only indicates the “good” and “failed”
states.
• It does not blink; it stays lit.
• There can be up to a 1-minute delay between the occurrence of an error condition
and the corresponding LED indication.
• There can be up to a 1-minute delay between the fixing of an error condition and
the corresponding LED indication.

accessory) changes this LED behavior.
If the HP Server Remote Management Card is installed, this LED displays:
• Green (steady): All components are OK
• Yellow (blinking at a rate of 1 Hz ): An internal component may fail soon (i.e.
system fan speed below threshold, predictive memory fail). Check the internal
diagnostic board or the system event log.
• Red (blinking at a rate of 2 Hz): An internal electrical component has failed or there
is a CPU or DIMM configuration error that prevents the system from booting.
Check the internal diagnostic board or the system event log.
If the HP Server Remote Management Card is not installed, the LED behavior
observes the following changes:
• It indicates the current states of the system fans. If the light is green, the fans are ok.
If the light is red, a fan has failed.
• It does not blink; it stays lit.

configuration error, etc.). Whenever an LED turns on, the HP Server tc4100 notifies you by turning the
System LED (located in the front panel) to amber or red.
•LEDs are powered as long as AC is present (Vstby). They do NOT turn off when the server is powered off.
•LEDs reflecting actual sensors should turn OFF when the sensors return to normal. Note that a system reset
always returns sensors to normal. If the error condition is still present when the system comes back up, the
sensor should go back to the error state within one minute.
Some LEDs are triggered by SEL events (for example, DIMM configuration error) and will only be cleared by
a system reset. After resetting, the LED should be cleared until a new SEL event is logged. These LEDs should
stay lit even if the server is turned off.

Applying Power to the HP Server tc4100
Powering Up the HP Server tc4100
1. Ensure that the HP Server tc4100's power cord or power cords are connected to the power source.
See Figure 1-8.
2. Press the Power button on the front control panel. See Figure 1-5.
NOTEEach time AC power is applied (power cord is plugged in), there is a 15 second delay
(self test) before the front control panel will respond to your actions.
Powering Down the HP Server tc4100
1. Log off all users and, if necessary, back-up files. Follow instructions in your network operating system
(NOS) documentation to gracefully shut down all networking software and applications.
2. Press the power switch on the HP Server tc4100 control panel when prompted by the operating system.
3. Normally, this completes the shutdown procedure.
NOTEThe power supply will continue to provide standby voltage to the HP Server tc4100 until
the power cord(s) is/are disconnected.
14
Chapter 1Control and Indicators
Connecting AC Power to Multiple-Server Configurations
The HP Server tc4100 temporarily draws a large “inrush current,” when first connected to an AC power source.
When the AC Power is turned off, inrush does not occur. However, in “standby mode” the AC power stays on
and the DC power is turned off.
Initially, the inrush current is much greater than the Server's normal operating current and, generally, the AC
power source can handle this normal inrush current. However, if you install several HP Servers on one circuit,
precautions are necessary. If there is a power failure and power is then restored, all the servers immediately
begin to draw inrush current at the same time. If the circuit breakers on the incoming power line have
insufficient capability, the breaker may trip and thus prevent the servers from powering up.
When preparing your site for installation, allow for the additional inrush current. See “Power Specification”
on page 124.
Sleep States (ACPI)
The HP Server tc4100 supports the ACPI (Advanced Configuration and Power Interface) standard, which is a
key component of a NOS's directed power management. The supported features are only available when an
ACPI-compliant NOS is installed on the Server. The term “sleep state” refers to any of several reduced power
consumption states in which normal NOS activity has ceased.
The Server supports several sleep states, including a sleep state with a short wake-up time, sometimes referred
to as “standby” or “suspend” by various operating systems. In this sleep state the Server appears to be off, and
is indicated by no display on the monitor and no activity for the CD-ROM or internal hard drives. However, the
power LED is slowly flashing and the fans continue to operate.
The HP Server has another sleep state with a slower wake-up time, sometimes referred to as “hibernate” by
various operating systems. In this sleep state, the server appears to be off as described earlier, but the fans and
the front panel power LED are also turned off. The unique feature of this sleep state (and the reason for its
slower wake-up time) is that information about the server's NOS state (open applications, screens, and so on)
is saved to disk before the server is placed in the sleep state. Upon wake-up, this information must be restored
from the disk. This method of restoring the server's operation is much faster than a complete rebooting of the
server. It still requires running all the start-up self-tests before starting the NOS, but loading the NOS and all
the previously opened applications is much faster.
The HP Server supports certain types of system activity, which is used as wake-up events from these sleep
states. These wake-up events can be generated from the power button, LAN activity, and scheduled events.
NOTEThe HP Server’s power management policies (transitions between various power states)
and the user options are specific to the particular ACPI-compliant NOS installed on the
server. If your NOS is ACPI-compliant, refer to the power management features in the
instructions provided for more information.
The HP Server’s power button can be configured to initiate a graceful shutdown of the NOS rather than an
immediate shutdown of the power supply. The power button configurations are dependent on the user interface
provided by the ACPI-compliant NOS. While power management is under the control of the ACPI-compliant
NOS, the HP Server’s power button is capable of an override in case of a non-responsive NOS.
NOTEThe HP Server power button will force a power-down without waiting for the NOS to
gracefully shut down the server, if the power button is pressed and held more than four
seconds.
CAUTIONIf the power button override is used, there is a strong possibility that data will be
corrupted or lost.
