Applying Power to the hp server

If you choose to use sleep states in conjunction with the hp server tc2120, refer to “Sleep States (ACPI)” later

in this section and your respective NOS.

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. Slide the switch to change the setting.

Switch is shown in 115 volts position

Figure 1-4. Input Voltage Selection Switch

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 1-4

.

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.

Powering-Up the Server

1. Turn on power to the monitor connected to the hp server. Turning on the monitor first ensures that video output auto-configures properly as the server boots up. For information about connecting the monitor, see

“Connecting Peripheral Devices” in

Chapter 3‚ Installing and Configuring .

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

3. Press the Power button on the lower front bezel. See Figure 1-1

. 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. For details refer to

“Configuring the hp server tc2120” in

Chapter 3‚

Installing and Configuring

and Chapter 6‚ Troubleshooting

.

NOTE When you disconnect the hp server from AC power, the server remembers the current power state (on or off) and returns to this state when you reconnect to AC power.

Powering-Down the Server

1. Make sure that you have exited all applications.

2. Use the shut down command in your operating system.

3. When prompted, press the power button on the hp server. 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.

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

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. Refer to Chapter 9‚

Specifications .

Sleep States (ACPI)

The hp server 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 ACPIcompliant 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. One of these is a “standby” sleep state, which has a short wake-up time.

In this sleep state the Server appears to be off—the monitor appears blank and there is no CD-ROM or internal hard drive activity (IDE or SCSI); however, the power LED displays a blinking green light and the system fan continues to operate.

5


The Server also may support 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 system fan 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 is restored from 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 Server supports certain types of system activity, which are used as wake-up events from these sleep states.

These wake-up events can be generated from the power button, keyboard or mouse activity, and scheduled events.

NOTE The 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

(BIOS) Setup Utility and the power management features provided in the NOS instructions for more information.

The hp server’s power button can be configured to initiate a graceful shutdown or “soft off” 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 ACPIcompliant NOS, the hp server’s power button is capable of an override in case of a non-responsive NOS.

NOTE The 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 for more than five seconds.

CAUTION If the power button override is used, there is a strong possibility of corrupted or lost data.

Refer to the BIOS Setup Utility in

Chapter 3‚ Installing and Configuring

and your NOS documentation for instructions on setting up Sleep States and transitioning into and out of the various states.

Mass Storage

This section describes how to install the internal mass storage devices, including the internal hard disk drives

(IDE or SCSI) and the optional tape backup (DAT) drive. The hp server tc2120 comes standard with one flexible disk drive, one IDE CD-ROM, and at least one SCSI or IDE hard disk drive, depending on the model.

The mass storage cage can hold two hard disk drives. A third hard disk drive may be installed in the fourth drive bay, located behind the upper front bezel.

16


Please refer to the appropriate topics listed in this section according to your server configuration (IDE or SCSI).

Shelf 1 (FDD)

Shelf 2 (CD-ROM)

Shelf 3 (Optional CD-ROM,

DVD Drive, or Backup Tape Drive)

Shelf 4 (3rd Hard Drive—Optional)

Drive Retaining Clips

Shelf 5 (1st Hard Drive—Standard)

Shelf 6 (2nd Hard Drive—Optional)

Figure 3-5. Mass Storage Locations

Mass Storage Guidelines

• General Guidelines o Use care when unpacking and handling the hard disk drives.

The hard disk drives are very susceptible to mechanical shock and can be easily damaged by a drop as short as one-quarter of an inch. If the drop would crack an egg, it will damage the drive.

o Do not stack drives.

o The server is internally limited to 6 mass storage shelves.

The flexible disk drive and CD-ROM drive, which are standard on all models of the hp server tc2120, occupy shelves 1 and 2 respectively. The first four mass storage shelves may also be referred to as common trays, or drive trays. See

Figure 3-5 .

• IDE Devices o The embedded IDE controller is an Enhanced-IDE dual channel controller and provides two connectors

(IDE-1 and IDE-2) for IDE devices.

Refer to

“System Board Layout”

in Chapter 9‚ Specifications .

o The IDE CD-ROM uses one connector on the cable from the IDE-2 connector, leaving one connector for an optional third hard drive or IDE device on the IDE model. The CD-ROM is configured as the master device, unless a third HDD is installed, which should be configured as the master device.

For the SCSI model the second IDE-2 connector could be used for any additional IDE device, such as

IDE hard drive.

o The primary IDE connector (IDE-1) and cable is used for the first or standard hard IDE drive and the second optional hard drive.

17


The bundled IDE CD-ROM and hard disk drive were put on separate IDE connectors to improve performance.

• SCSI Devices o Use only low voltage differential (LVD) SCSI devices.

o Do not use high voltage differential (HVD) SCSI devices in the server or damage to the controller and other devices may occur. o Ensure that the SCSI devices you install do not have terminations installed.

The SCSI drives are connected to a terminated cable and do not require termination on the SCSI drive.

o Use only HP Ultra 160 SCSI LVD (1-inch) low profile 3.5-inch hard disk drives for the hard disk drive cage.

o The optional HP backup tape drive comes with a 50-to-68-pin adapter to connect to the 68-pin SCSI connector on the SCSI cable used for connection of backup tape drive.

The optional HP backup tape drive may slow down access time for the Ultra-160 SCSI hard drives. If this is the case, HP recommends adding another single channel SCSI controller to control the slower backup tape drive.

Boot Priority

The hp server tc2120 is provided in two models, IDE or SCSI, and the model type affects the boot priority. The hp server searches for bootable devices in a specific order, which is set up in the BIOS Setup Utility. The SCSI

Controller in the server scans for a boot device starting at device ID 0 and works up through the ID numbers (0-

15). The SCSI controller board is always SCSI ID 7. The optional backup tape drive will use SCSI address ID 3.

NOTE The boot order can be changed by pressing F8 during the

POST or by using the server’s (BIOS) Setup Utility. Refer to

“BIOS Setup Utility” later in this chapter for more

information. You may also activate the Network Boot by pressing F12 during the POST.

Default Boot Order:

1. CD-ROM drive

2. Flexible disk drive

3. IDE hard drive (if present)

4. SCSI hard drive in any PCI slot (if present)

5. Other bootable devices in any PCI slot

18


Mass Storage Devices

This section provides the configuration of the IDE and SCSI mass storage devices in the hp server tc2120.

IDE Model Controller Configuration

The embedded IDE controller is available for both models (IDE or SCSI) of the hp server. The embedded IDE controller is an Ultra ATA 33/66/100 dual channel controller, which provides IDE-1 and IDE-2 connectors.

Each channel can only control two IDE devices.

The IDE server model uses the IDE-1 for the boot drive and the IDE-2 connector for the IDE CD-ROM. The

BIOS Setup Utility can be used to change the boot order of the flexible disk drive and the IDE devices. Refer to

“BIOS Setup Utility”

later in this chapter for more information.

SCSI Model Controller Configuration

The base SCSI model of the hp server tc2120 has at least one SCSI hard drive (shelf 5) located in the drive cage and connected to the factory installed SCSI controller. The single channel SCSI controller board provided with the SCSI model uses the SCSI Select Utility to control the SCSI controller board settings. If you order the SCSI model, you typically do not need to configure the SCSI controller, because the utility will automatically recognize all SCSI devices connected to it.

Run the SCSI Select Utility to verify or modify the SCSI controller settings, low-level format SCSI disks, or

verify SCSI media. Refer to “SCSI Configuration Utility” later in this chapter for further information.

The single channel Ultra-160 PCI SCSI controller board provided with the SCSI model includes three internal

SCSI connectors and is normally installed in PCI slot 1. Two of the internal connectors are used for legacy products, and the third is used for your SCSI drives. The SCSI cable provided has 5 connectors, (4 for SCSI devices and 1 for the SCSI controller board) and one terminator on the end of the cable.

CAUTION You must not connect high voltage differential (HVD) SCSI devices on the SCSI bus or you will damage the other LVD

SCSI devices.

7. Ensure that the backup tape drive is not terminated and ensure that the SCSI ID jumper is set for address =

ID 3 on the tape drive.

The optional HP SureStore DAT 24i backup tape drive is shipped with the default setting of SCSI address

= ID 3. Refer to the documentation provided with the tape drive.

8. Install the backup tape drive, as described below:

25


a. Place it into the tray and use the screws provided to secure it to the tray. See Figure 3-11

.

The optional HP SureStore DAT 24i backup tape drive is a single-ended drive and normally comes with the 5¼ inch mounting brackets installed on the tape drive. If the brackets are not pre-installed, follow the instructions provided with the tape drive to connect the 5¼-inch mounting brackets to the tape drive before installing the tape drive into the third drive tray.

b. Insert the backup tape drive mounted in the tray into the third shelf.

The tabs should snap into place when the third drive tray is pushed all of the way into the third shelf.

CAUTION

9. Connect the SCSI data and power cables to the rear of the backup tape drive.

The SCSI data and power cables for the tape drive should already be routed to the tape drive. If they are not, locate the free SCSI and power connectors and route them to the tape drive.

NOTE

Install and remove connectors carefully, and avoid displacing any of the pins.

The slower speed of the tape drive may slow disk access time for the Ultra-160 SCSI drives. You should install an additional

SCSI controller board to control the backup tape drive separately from the Ultra-160 SCSI drives. You may use the internal SCSI cable provided with the second SCSI controller board to connect to the tape drive.

10. Replace the upper bezel and the left side cover.

11. Replace the external cables, power cord, and then restore power to the server.

The SCSISelect Utility automatically detects the new SCSI backup tape drive, but you should check the

SCSISelect settings and make changes as necessary.

Accessory Boards

The system board in the hp server tc2120 provides five PCI slots (P1 through P5), 64-bits at 33 MHz bus speed.

Four of the slots support 3.3 volt cards; the fifth (blue) slot supports a +5 volt card. Some PCI slots may come with pre-installed boards. The SCSI model requires the first slot, (P1) for the SCSI controller board.

35


Tested PCI Boards

For a list of tested PCI boards, check for compatibility in the Hardware Tested Products list for the hp server tc2120 under the Technical Support topic for the specific NOS used in the server at HP’s web site at: http://www.hp.com/

CAUTION Some accessory board outputs may exceed U.S. National

Electrical code (NFPA 70) Class 2 or limited power source limits and must use appropriate interconnecting cabling in accordance with the National Electrical Code.

NOTE All Hewlett-Packard accessory boards comply with the U.S.

National Electrical code (NFPA 70) Class 2.

Tools Required

These tools may be needed for preparing the accessory boards for installation in the server:

• Torx T-15 screwdriver

• ¼-inch flat blade screwdriver

• An anti-static service kit (3M 8501/8502/8503 or equivalent). This kit includes a static-dissipating work surface, a chassis clip lead, and a wrist strap.

Guidelines

The following sections provide the guidelines necessary to install the PCI accessory boards into the server.

NOTE Some full-length PCI boards may need a plastic “handle”

(board extension) on one end to stabilize the board in the server. If the board requires one and it is not installed, you may need to install the handle on the board, before installing it in the hp server. See

Figure 3-23 .

IRQ Settings

The IRQ settings are automatically assigned and do not require user intervention. The hp server uses the Plugand-Play feature of the PCI boards to correctly assign its resources automatically.

Boot Priority

The server’s boot priority (BIOS search order for a boot drive) should be considered when selecting a PCI slot on the system board. This is especially important if you are installing a board that requires an early number in

the boot order. The accessory board’s boot priority is set by its slot location in the boot order. See Figure 3-19

.

If the single SCSI controller board is used to control internal SCSI drives (SCSI model), it will be early in the boot order. The single SCSI controller board has two SCSI connectors, but only one SCSI connector can be active at a time. The server scans the active SCSI connector for a boot device starting at device ID 0 and works up from there.

36


By default the server searches for boot devices in the following order depending on the server model:

Default Boot Order:

1. CD-ROM drive

2. Flexible disk drive

3. IDE hard drive (if present)

4. SCSI hard drive in any PCI slot (if present)

5. Other bootable devices in any PCI slot)

NOTE The boot order can be changed by pressing F8 during the

POST, or by using the server’s (BIOS) Setup Utility. For more

information, refer to “BIOS Setup Utility” later in this

chapter. You may also activate the Network Boot by pressing

F12 during the POST.

Installing an Accessory Board

Use this procedure to install accessory boards and observe the installation guidelines listed earlier.

1. If the server is already installed and working, power down the server.




3. Remove the side cover and lay it aside.



WARNING The power supply will continue to provide standby current to the server until the power cable is disconnected.


4. Lay the server on its side (components showing) for the best access to the accessory board slots.

5. Read the documentation included with the accessory board and follow any special instructions.

6. Identify the accessory slot number to be used. See Figure 3-19

.

The SCSI model should already have the SCSI controller board installed in PCI slot P1.

4 Diagnostics

When the server boots, a series of tests are displayed on the screen. The number of tests displayed depends on the configuration of the server. The following are the types of errors you might get with the hp server.

• Built-in diagnostic error messages.

• BIOS and other error messages. These are errors detected by the system BIOS outside the built-in diagnostics or application errors.

To see the Power On Self-Tests (POST):

• The hp server must be functionally able to run the diagnostics.

• The video system must be functional.

• The keyboard must be functional.

NOTE The BIOS ROM version number is displayed on the monitor screen during power-up.

WARNING Always turn off the power and disconnect the power cord to the server before attempting to remove the cover and touch the internal components. Failing to do so can expose you to electric shock and damage the server’s components. The power switch does NOT turn off standby power; you must disconnect the power cord to turn off standby power.

Power-On Self Test (POST)

The diagnostics (Power-On Self-Tests, or POST) run automatically each time the server is powered on. These diagnostics, which reside in the BIOS ROM, isolate server-related logic failures and indicate the board or component that needs to be replaced, as indicated by the error messages. Most server hardware failures will be accurately isolated by the diagnostics.

There are two types of error messages:

• Power-on self-test (POST) messages – These text messages display in normal video (white text on black background). If a text message error occurs during the POST, details of the error are displayed. Follow the

instructions on the screen or refer to Table 4-1 in this section for instructions.

• Beep Codes – These are a series of audible beeps, which occur during the boot process before the video display can initialize allowing the visual messages of the POST routines to appear. If you hear a series of audible beeps before the video appears on screen, refer to the beep codes listed in

Chapter 5‚ Error Messages .

Ιf no message appears (screen is blank), listen for the beep codes and refer to

Chapter 5‚ Error Messages

for more information. If no message appears but the server stops after POST, see

“Server Passes POST, but Does

Not Function”

in Chapter 6‚ Troubleshooting

hp server Diagnostics for Windows Utility

The purpose of hardware diagnostic software is to provide tools for checking hardware problems. By design, diagnostic software executes simple tests of each hardware component. Usually such tests confirm that hardware is not the source of server problems, allowing you to focus on other possible sources such as operating system configuration parameters, network connections, and application software configuration parameters.

If hardware problems are confirmed, the diagnostic software program can sometimes detect and diagnose the system or specific server component causing the problem. In addition, diagnostic tools can capture information that allows support personnel to quickly assess the condition of the server.

In order to be effective, diagnostic software tools must be used in the context of a wider troubleshooting procedure.

77


Network Interface Card (Installed) Problems

See the appropriate Network Interface Card documentation.

Symptom:

• The NIC adapter cannot connect to the network.

Action:

1. Ensure the cabling is installed properly.

2. If you’re directly connecting two servers (with no hub or other device), use a “crossover” cable.

Most hub and switch connections require a straight-through cable; but consult the documentation.

3. Verify there are no resource conflicts between the NIC and any other accessories in the server.

4. Check the (BIOS) Setup Utility for resource conflicts.


5. Check the LEDs on the adapter at the back of the server to see if any show activity.

No lit LEDs probably indicate a bad network cable, hub connection, or other network error.

6. Ensure you’re using the latest and most correct drivers.

7. Verify the drivers are intended for this NIC adapter.

8. Ensure the port on the switch or hub (or other device) has the same duplex setting as the adapter.

9. If you configured the adapter for full duplex, make sure the switch port is also configured for full duplex.

Setting the wrong duplex mode can degrade performance, cause data loss, or result in lost connections.

10. Test the adapter as directed in the installation tasks for each operating system.

11. Also check the “README” files on the support disk provided by the NIC adapter vendor.

Installation Problems

To troubleshoot an installation problem, you need to determine if the problem is hardware or software related.

1. Verify all cables and boards are securely plugged into the appropriate connectors or slots.

2. Ensure the server is configured properly.

Most installation problems are the result of incorrect BIOS and SCSI configurations of the server.

a. Verify that the system BIOS is the latest. See

“BIOS Update” earlier in this chapter.

b. Verify the SCSI BIOS configuration. See “SCSI Problems” earlier in this chapter.

c. If the network is not functioning, consult your network operating system manual and its requirements.

To determine if the problem is a hardware error, follow these steps:

1. If necessary, log users off the network and back up the server.

78

Chapter 6

2. Power down the server and disconnect the power cord from the AC power source.

Troubleshooting

WARNING Before removing the left side cover, always unplug telephone cables and disconnect the power cord. Unplug telephone cables to avoid exposure to shock hazard from telephone ringing voltages. Disconnect the power cord to avoid exposure to high energy levels that may cause burns when parts are short-circuited by metal objects such as tools or jewelry.

3. Remove the server’s left side cover.

4. Simplify the hp server configuration to the minimum required:

The minimum configuration would include a monitor, one flexible disk drive, one CD-ROM drive, one hard disk drive, keyboard, mouse, and embedded NIC.

5. Boot the server.

o If the server does not operate properly, consult the troubleshooting steps in “Server Does Not Power

On” in this chapter.

o If you get an error message or beep code, refer to


o If there is no error messages or beep code, refer to

“Server Passes POST, but Does Not Function” earlier

in this chapter.

6. Re-install the third-party options, one at a time, checking the server after each installation (repeat steps 2 through 5).

This allows you to locate the defective option and replace it if necessary. After adding all options, if the problem persists, call your HP Customer Service provider.
