Chapter 3 Installing and Configuring Memory Installation Guidelines The hp server tc2120 uses PC2100 (266 MHz) buffered ECC DDR 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, 512 MB, or 1 GB in any combination. • Supported memory capacity ranges from 128 MB to 4 GB maximum (1 GB x 4 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 4). However, HP recommends loading the DIMMS by size, starting at slot 4 with the smallest DIMM size and filling the slots in reverse order (4, 3, 2, 1). See Figure 3-12 for DIMM slot locations. • Open slots between DIMMs are permitted. • When handling DIMMs, observe anti-static precautions to avoid damage. Installing Additional DIMMs 1. If the system is already installed and working, power off the system. Refer to Chapter 1, Controls and Indicators. 2. Disconnect the power cables and any external cables connected to the system. If necessary, label each one to expedite re-assembly. 3. Remove the side cover and lay it aside. Refer to "Opening and Closing the hp server" earlier in this chapter. WARNING The power supply will continue to provide standby current to the hp server tc2120 until the power cable is disconnected. 4. Lay the server on its side (components showing) for the best access to the DIMM slots. CAUTION The memory modules (DIMMs) are sensitive to static electricity and can be easily damaged by improper handling. Do the following when handling the accessory kit: Leave the memory module in the anti-static container until you are ready to install it. Always use an anti-static wrist strap and a grounding mat. Before you remove a memory module from the anti-static container, touch a grounded, unpainted metal surface on the hp server to discharge static electricity. 5. Locate the DIMM slots and select a DIMM slot for installation. See Figure 3-12. DIMMs may be installed in any combination, in any slot, but HP recommends loading the DIMMS by size, starting at slot 4 with the smallest DIMM size and filling the slots in reverse order (4, 3, 2, 1). 28

Memory Installation Guidelines
The hp server tc2120 uses PC2100 (266 MHz) buffered ECC DDR 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, 512 MB, or 1 GB in any combination.
•
Supported memory capacity ranges from 128 MB to 4 GB maximum (1 GB x 4 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 4). However,
HP recommends loading the DIMMS by size, starting at slot 4 with the smallest DIMM size and filling the
slots in reverse order (4, 3, 2, 1). See
Figure 3-12
for DIMM slot locations.
•
Open slots between DIMMs are permitted.
•
When handling DIMMs, observe anti-static precautions to avoid damage.
Installing Additional DIMMs
1.
If the system is already installed and working, power off the system.
Refer to
Chapter 1‚ Controls and Indicators
.
2.
Disconnect the power cables and any external cables connected to the system.
If necessary, label each one to expedite re-assembly.
3.
Remove the side cover and lay it aside.
Refer to
“Opening and Closing the hp server”
earlier in this chapter.
4.
Lay the server on its side (components showing) for the best access to the DIMM slots.
5.
Locate the DIMM slots and select a DIMM slot for installation.
See
Figure 3-12
.
DIMMs may be installed in any combination, in any slot, but HP recommends loading the DIMMS by size,
starting at slot 4 with the smallest DIMM size and filling the slots in reverse order (4, 3, 2, 1).
WARNING
The power supply will continue to provide standby current to
the hp server tc2120 until the power cable is disconnected.
CAUTION
The memory modules (DIMMs) are sensitive to static
electricity and can be easily damaged by improper handling.
Do the following when handling the accessory kit:
Leave the memory module in the anti-static container until
you are ready to install it.
Always use an anti-static wrist strap and a grounding mat.
Before you remove a memory module from the anti-static
container, touch a grounded, unpainted metal surface on the
hp server to discharge static electricity.
