• The power connector accepts a standard power cable to connect the HP Server tc2100 with the site
power source.
• The input voltage selector switch is used to adapt the power supply to the input line voltage. The two
switch settings are 115 volts or 230 volts, and 230 volts is the default setting.
• The mouse port accepts a standard mouse with a PS/2 connector.
• The keyboard port accepts a standard keyboard with a PS/2 connector.
• Two USB ports are provided for printers, external modems, a keyboard and a mouse, but these features
are NOS dependent.
• The COM 1 port is a standard serial port.
• The Parallel Port is a standard parallel printer port, which supports Extended Capabilities Port
(ECP)/Enhanced Parallel Port (EPP).
• The Monitor Port (SVGA) interface specifications are listed in the following tables "HP Server
Hardware Specifications" and "Video Display Modes" of Chapter 1, "Specifications."
• The COM 2 port is a standard serial port.
• The SCSI model has an external SCSI port for external SCSI devices provided by the single channel
SCSI controller board, but can only be used when no SCSI devices are connected internally.
• Keylock mechanism provides mechanical security for the left side panel to prevent access to the internal
components.
13
Chapter 2 Controls, Ports, and Indicators
• The LAN port is included as an embedded controller based on Intel's 82559 10/100 BaseT Fast Ethernet
Controller. It has a RJ-45 LAN connector on the rear panel. The LED on the front panel is used to
indicate LAN activity.
• System Fan is a variable speed fan controlled by thermal sensors on the system board. The system fan
speed can also be controlled by the fan speed settings in the (BIOS) Setup Utility.
Applying Power to the HP Server
Powering-Up the HP Serv er
NOTE Turn on power to the monitor connected to the HP Server before you power-on the HP
Server. This allows proper auto-configuration of video output of the Server as it boots up.
CAUTION To prevent damage to the power supply, check the Input Voltage selector switch before
connecting the Server and its power cord to a voltage source.
1. Ensure the Input Voltage selector switch is set for the correct input voltage, before connecting the power
cord to a voltage source. See Figure 2-4.
Power
Connector
(Switch show n in
11 5 vol t s position.)
2. Ensure the HP Server's power cord is connected to the power source. See Figure 2-4.
3. Press the Power button on the lower front bezel. See Figure 2-1.
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
Chapter 8, "Configuring the HP Server" and Chapter 9, "Troubleshooting."

o Schedule the power down for a time when the fewest users will be affected by the Server's
downtime.
o If you will be doing any kind of hardware or software upgrade , be sure your Server's data has been
backed up.
2. Follow instructions in your network operating system (NOS) documentation to gracefully shut down all
networking software and applications.
3. Press the power switch on the HP Server's control panel when prompted by the operating system.
Normally this completes the power down procedure.
Chapter 2 Controls, Ports, and Indicators
NOTE The power supply will continue to provide standby current to the Server until the power
cable is disconnected from the rear panel.
Multiple-Server Configurat ions
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 and the power cord is plugged into AC
power). The inrush current is much greater than the Server's normal operating current and general ly, 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. See "Power Specifications"
in Chapter 1.
Sleep States (AC PI)
The HP Server supports the ACPI (Advanced Configuration and Power Management 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 a steady orange and the fans are operating.
The Server may also 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 tha n 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 sleep states.
These wake-up events can be generated from the power button, keyboard and 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 respective NOS is ACPI-compliant, refer to the (BIOS) Setup Utility and
the power management features described in the instructions provided 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 ACPI-compliant 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 when the power button is pressed and held in excess of
four seconds.
15
Chapter 2 Controls, Ports, and Indicators
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 8, “Configuring the HP Server” and your NOS documentation for
instructions on setting up Sleep States and transitioning into and out of the various states.

4 Maintenance Guidelines
Introduction
This chapter provides the HP Tower Server tc2100’s maintenance guidelines when removing or replacing the
mass storage devices, DIMM memory, accessory boards, and processors.
Mass Storage
The HP Server tc2100 comes standard with one IDE CD-ROM and one flexible disk drive with various
possible configurations of SCSI or IDE hard disk drives, depending on the model (SCSI or IDE). The Server
is limited to six internal mass storage devices (including a tape back up drive), four in the front shelves (or
common trays) and two in the removable drive cage accessed from the side of the Server.
Mass Storage G uidelines
• 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
tc2100, occupy shelves 1 and 2 respectively. The first four mass storage shelves may also be referred
to as common trays, or drive trays.
o If a backup tape drive is used, it occupies shelf 3, leaving only three mass storage devices available
for shelves 4-6, and at least one is required for the boot drive.
• 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 1, "Specifications."
o The IDE CD-ROM uses one connector on the cable from the IDE-2 connector, leaving one
connector for the optional third hard drive on the IDE model. The CD-ROM is configured as the
master device, unless a third HDD is installed, which should be configured for 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, but this cable is not provided for the SCSI model.
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 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.
23
Chapter 4 Maintenance Guidelines
o Use only HP Ultra-160 SCSI LVD (1-inch) low profile 3.5-inch hard disk drives for the removable
hard disk drive cage.
o Only use an HP Ultra-160 SCSI LVD drive as the optional third drive.
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.
o 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 tc2100 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 Utility.
IDE Model Boot Order:
1. Flexible disk drive
2. IDE CD-ROM drive
3. IDE hard drive (boot drive)
4. PCI slot P1 (32-bit slot)
5. PCI slot P2 (32-bit slot)
6. PCI slot P3 (32-bit slot)
7. PCI slot P4 (32-bit slot)
8. PCI slot P5 (32-bit slot)
SCSI Model Boot Order:
1. Flexible disk drive
2. IDE CD-ROM drive
3. IDE hard drive (if boot drive)
4. SCSI devices
5. PCI slot P1 (32-bit slot)
6. PCI slot P2 (32-bit slot)
7. PCI slot P3 (32-bit slot)
8. PCI slot P4 (32-bit slot)
9. PCI slot P5 (32-bit slot)
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 using the Server's (BIOS) Setup Utility and the SCSISelect
Utility.

Chapter 4 Maintenance Guidelines
IDE Mass Storag e Device s
This section provides the configuration of the IDE mass storage devices, if you have selected an IDE version
of the HP Server tc2100.
IDE 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 DMA33/66/100 E-IDE 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
Setup Utility (BIOS) can be used to change the boot order of the flexible disk drive and the IDE devices.
Refer to Chapter 8, "Configuring the HP Server," for more information.

SCSI Mass Stor age Dev ices
This section provides the configuration of the SCSI mass storage devices, if you have selected a SCSI version
of the HP Server tc2100. The base SCSI model configuration has at least one SCSI hard drive (shelf 6)
located in the removable drive cage and connected to the factory installed SCSI controller.
SCSI Controller Configuration
The single channel SCSI controller board provided with the SCSI model uses the SCSISelect 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 SCSISelect 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 Chapter 8, "Configuring the HP Server," in the HP Server tc2100 Installation
Guide for further information.
CAUTION You must not connect high voltage differential (HVD) SCSI devices on the SCSI bus or
you will damage the other LVD SCSI devices.
The single channel Ultra-160 PCI SCSI controller board provided with the SCSI model includes two SCSI
connectors and is normally installed in PCI slot P1. 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.
• 1 internal 68-pin connector – This internal connector is used to control the internal SCSI drives; up to a
total of four SCSI devices.
25
Chapter 4 Maintenance Guidelines
• 1 external 68-pin connector – This external SCSI connector is only used for external SCSI devices and
requires no additional internal cabling or switch settings. This connector supports up to 15 devices
connected to it externally.
NOTE Only one 68-pin connector on the SCSI controller board can be used as the active SCSI
connector. Therefore, you can not connect external SCSI devices to the external connector
when there are active internal SCSI devices connected to the internal SCSI connector.
The HP Server tc2100 will support an HP NetRAID 1M controller board, separate from the SCSI controller
board.

supported by Hewlett-Packard.
** A 50-to-68-pin SCSI adapter is provided with the HP backup tape drive.
*** The single channel SCSI controller c an support up to 15 devices on one connect or at a time; however, there a r e only enough
internal storage shelves for 3 hard disk drives and 1 optional tape backup device. The external connector is only u sed to control
external SCSI devices when th er e are no internal SCSI devices.
External SCSI Connector
The HP Server tc2100, SCSI model, has an external SCSI connector at the rear of the Server. This SCSI port
cannot be used if there are active internal SCSI devices. The SCSI controller provided with the SCSI model
of the Server is a single channel controller and cannot support internal and external SCSI devices at the same
time.
Memory Guidelines
• The HP Server tc2100 only uses 133 MHz (PC133) SDRAM DIMMs, which are electrically different
from the EDO and PC100 SDRAM memory modules used in previous HP Server models.
• DIMMs sizes supported are 128 MB, 256 MB, or 512 MB buffered in any combination.
• Supported memory capacity ranges from 128 MB to 1.5 GB maximum (512 MB per DIMM slot x 3
DIMM slots total). The minimum capacity is 128 MB (one DIMM).
• DIMM sizes may be mixed on the system board and may be loaded in any order (1 through 3).
However, HP recommends starting at slot 1 and filling the slots in order: 1, 2, and 3.
• Empty slots between DIMMs are permitted.
• When handling DIMMs, observe anti-static precautions to avoid damage.
To ensure you have the correct DIMMs before installation, refer to one of the following for a list of qualified
DIMMs:
• HP Order Assistant on the HP web site at:
27
Chapter 4 Maintenance Guidelines
http://www.hp.com/go/Server
• HP Customer Service
The video memory is limited to 4 MB on the system board and cannot be upgraded.
Accessory Board Guidelines
The system board in the HP Server tc2100 provides up to five 32-bit PCI slots (P1 through P5).
Tested PCI Board s
For a list of tested PCI boards, check for compatibility under the Hardware Tested Products list for the HP
Server tc2100 under the Technical Support topic for the specific NOS used in the Server at HP’s web site:
http://Server.hp.com/Server/support/compatibility/compatibility.asp
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 inter-connecting cabling
in accordance with the National Electrical Code. (All HP boards comply with Class 2.)
IRQ Settings
The IRQ settings are automatically assigned and do not require user intervention. The HP Server uses the
Plug-and-Play feature of the PCI boards to correctly assign the resources automatically.
Processor Guidelines
This HP Server supports the Celeron and Pentium III processors and each one should have its own heatsink
and cooling fan.
CAUTION If good contact is not made between the processor and the thermal patch on the heatsink,
the processor will overheat and possible damage may occur.
• Ensure you open the ZIF lever before removing or installing the processor into the socket.
The processor socket uses a ZIF (Zero Insertion Force) lever to secure the processor in the socket.
• The ZIF lever should make a clicking sound when it closes completely.
• Ensure you align Pin-1 of the processor with Pin-1 of the processor socket when installing the
processor, or processor pins will be damaged.
• Each processor requires a heatsink with a cooling fan attached.
The Celeron processors use a slightly different heatsink with a smaller cooling fan than the Pentium III
heatsink-co oling fan a ssembly.
CAUTION To prevent damage to the thermal patch, do not slide the heatsink around on the
processor once it is in place. Rocking it slightly to one side or the other to install both
latches is acceptable.
28
• Each heatsink should have an undamaged thermal patch on the bottom of the heatsink.
The thermal patch provides the thermal bonding between the processor and the heatsink.
• The plastic sheet/tab on the thermal patch must be removed before placing the heatsink on the processor.
Some thermal patches come with a small plastic sheet (with a finger tab) covering the non-adhesive side
of the patch to help protect the thermal material.
Chapter 4 Maintenance Guidelines
• Ensure the front ridge on the bottom of the heatsink fits into the groove between the processor socket
and processor and both ridges should straddle the processor.
The bottom of each heatsink has two ridges, which are used to align the heatsink with the processor.
• Both latches (hook and thumb) on the heatsink must be connected to the processor socket base or the
processor will overheat.
The mechanical latches on the heatsink ensure a good thermal bond between the heatsink and the
processor through the thermal patch.
• If the processor is upgraded to a faster processor speed with a different front side bus (FSB) speed than
the previous processor, the circuitry on the system board detects the change and automatically adjusts to
the faster fron t side bus speed.
• The HP Server tc2100 only supports 100 MHz and 133 MHz FSB speeds.
