P2 - P5 PowerStations: DRAM Replacement
Background
Electrostatic Discharge Precautions
CTC Parker Automation
This document describes the procedure for adding or replacing the DRAM
on P2-P5 PowerStations. All PowerStations use DRAM that is comparable
to what is found in most laptop PCs. The CPU card provides two 144 pin
SODIMM sockets, each of which accepts 8, 16, 32, 64 or 128 MB, 3.3 V
power level SODIMMs.
Note
The CPU card only supports SDRAM SODIMM modules. EDO
SODIMM is not supported.
This procedure requires the following tools:
•
Slotted head (#2) screwdriver
•
Phillips head (#0) screwdriver
•
Quarter-inch nut driver
•
Needle nose pliers
Modern integrated electronic devices, especially CPUs and memory chips,
are extremely sensitive to electrostatic discharges (ESD) and fields. Before
you disassemble the PowerStation, be sure to follow these simple
precautions to protect you and the PowerStation from harm resulting from
ESD.
1. To avoid electric shock, always disconnect the power from the
PowerStation before you remove the back cover or separate the back
cover from the front panel. Do not touch any components of the CPU
card or other cards while the PowerStation is on.
2. Disconnect power before making any hardware configuration
changes. The sudden rush of power as you connect a jumper or install
a card may damage sensitive electronic components.

If you have a P2 PowerStation, continue to the next procedure, Disassembling a P2 PowerStation. If you have a P3, P4, or P5 PowerStation, skip the next procedure and proceed to Disassembling a P3-P5 PowerStation on page 4.

- Page 4 P2 - P5 PowerStations: DRAM Replacement Disassembling a P3-P5 PowerStation 1. Turn off power to the unit. 2. Disconnect the unit from the power source. 3. Remove the unit from its enclosure, if installed. Caution You must wear an ESD wrist strap connected to a good, known, earth ground before completing the next step to avoid damaging the unit.

Protective Cover Fastener Connector and Ribbon Cable 11. Remove the protective cover, carefully sliding it from beneath the remaining ribbon cables.
- Page 6 P2 - P5 PowerStations: DRAM Replacement Removing a DRAM Module Follow these instructions to remove a DRAM module from the CPU card. 1. Locate the DRAM socket(s) on your PowerStation. On the P2, P3 and P5 PowerStations, the DRAM slots are located in a similar position as the DRAM slots on the P4 PowerStation shown below.
- Page 7 CPU card of a P2, P3, P4 or P5 PowerStation. Important The PNY (manufacturer) type DRAM module will not fit properly on a P2 PowerStation. It blocks the Power Supply mounting screws. 1. Carefully insert the DRAM module into its socket at a 30-degree angle.
- Page 8 P2 - P5 PowerStations: DRAM Replacement 7. Turn on the unit. Note If the PowerStation begins to beep when you power up the unit, it means that the DRAM module(s) are not properly seated. If necessary, repeat the procedure and reseat the DRAM module(s). 8.
