hp server tc2110 - applying power


This document addresses applying power to the HP Server tc2110.

Connecting the power cords

WARNING: For your safety always connect equipment to a grounded wall outlet. Always use a power cord with a properly grounded plug, such as the one provided with the equipment, or one in compliance with your national safety standards. This equipment can be disconnected from the power by removing the power cord from the power outlet. This means the equipment must be located close to an easily accessible power outlet.

Setting the input voltage

Remove the warning label covering the power connector, and ensure that the voltage setting is correct for your country. (The voltage is set during manufacture and should already be correct.)

Connecting the power cords

  1. Connect the power cords to the rear of the monitor and the HP Server. (The connectors are shaped to go in one way only.)

  2. Connect the monitor’s power cord and the HP Server’s power cord to a grounded outlet. See Figure 1.

NOTE: Hewlett-Packard does not support power supply upgrades. Power supply installation information is only intended to assist with the replacement of a defective power supply unit. For your safety, only replace your power supply unit with the one provided by HP Support Services.


Turn on the server

  1. Turn on the monitor connected to the HP Server.

  2. Turning on the monitor first ensures that video output auto-configures properly as the server boots up.

  3. Ensure that the Input Voltage selector switch is set for the correct input voltage.

  4. Press the Power button on the lower-front bezel.

  5. When you press the power button on the front bezel, the server powers up and loads the operating system. The system runs a set of Power On Self Tests (POST) during this process.


Turning off the server

  1. Make sure that you have exited all applications.

  2. Use the shut down command in your operating system’s Start menu (for Windows NT ® 4.0 and Windows® 2000, and Windows XP operating systems).

  3. When prompted, press the power button on the HP Server.

    WARNING: The power supply will continue to provide standby current to the server until the power cord is disconnected from the rear panel.

If you want to force the HP Server to shut down (for example, after the operating system has crashed), press and hold down the power button for approximately 5 seconds.

Connecting power to multiple-server configurations

The HP Server temporarily draws a large “inrush current,” when first connected to an AC power source. This also occurs when the server is in a standby mode (power is turned off, but the power cord is plugged into AC power). The inrush current is much greater than the server’s normal operating current and generally, the AC power source can handle the 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.
