SAFETY PRECAUTIONS

Observe the following safety precautions before performing any installation or break/fix procedures involving

disassembly or re-assembly:

Turn off the system and any attached peripherals.

Disconnect the system and any attached peripherals from AC power, and then remove the battery.

Disconnect any telephone or telecommunications lines from the system.

Use a wrist grounding strap and mat when working inside any computer system to avoid electrostatic

discharge (ESD) damage.

After removing any system component, carefully place the removed component on an anti-static mat.

Wear shoes with non-conductive rubber soles to help reduce the chance of being shocked or seriously

injured in an electrical accident.

Standby Power

Dell products with standby power must be completely unplugged before opening the case. Systems that

incorporate standby power are essentially powered while turned off. The internal power allows the system to be

remotely turned on (wake on LAN), suspended into a sleep mode, and have other advanced power management

features. After unplugging the system, allow the charge to drain from the circuits by waiting approximately 30 to 45

seconds before removing components.

ESD

ESD is a major concern when handling components, especially expansion cards and system boards. Very slight

charges can damage circuits in ways that may not be obvious, such as intermittent problems or a shortened

product lifespan.

WARNING: Do not use an ESD grounding strap when working on the internal parts of a monitor, like the

CRT, because the stored voltage is extremely harmful.

To prevent static damage, do the following:

Use an ESD wrist strap that is properly grounded.

If a strap is not available, discharge static electricity from your body before you touch any of your


6 of 92 09/01/2011 10:10 PM

computer's electronic components, by touching an unpainted metal surface on the computer chassis.

Periodically touch an unpainted metal surface to remove any static charge your body may have

accumulated.

Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor pads and

workbench pads.

When handling static-sensitive components, grab them by the sides, not the top. Avoid touching pins and

circuit boards.

When unpacking a static-sensitive component from its shipping carton, do not remove the component from

the anti-static packing material until you are ready to install the component. Before unwrapping the

anti-static packaging, be sure to discharge static electricity from your body.

Before transporting a static-sensitive component, place it in an anti-static container or packaging.

Lifting Equipment

CAUTION: Do not lift greater than 50 pounds independently. Always obtain assistance from a second

person or utilize a mechanical lifting device.

Adhere to the following guidelines when lifting equipment:

Get a firm balanced footing. Keep your feet apart for a stable base, and point your toes out.1.

Bend your knees. Do not bend at the waist.2.

Tighten stomach muscles. Abdominal muscles support your spine when you lift, offsetting the force of the

load.

3.

Lift with your legs, not your back.4.

Keep the load close. The closer it is to your spine, the less force it exerts on your back.5.

Keep your back upright, whether lifting or setting down the load. Do not add the weight of your body to the

load. Avoid twisting your body and back.

6.

Follow the same techniques in reverse to set the load down.7.

SYSTEM MEMORY

The memory architecture featured in the Dell PowerEdge 2850 is DDR2 PC3200 240-pin SDRAM memory. The

memory is also registered, error-checking and correction (ECC), 72-bits wide and operates at 400-MHz, regardless

of host bus speed.

Single and Dual-Rank DIMMs

Determining if a DIMM is a single-rank DIMM or a dual-rank DIMM is difficult upon visual inspection. A single-rank

DIMM may have memory chips on both sides of a DIMM. The best way to decide if the DIMM is a single-rank

DIMM or a dual-rank DIMM is to look at its attached label. The following image contains the labeling convention

used to determine the exact specifications of the DIMM.


72 of 92 09/01/2011 10:10 PM

NOTE: In this example, 2R represents a dual-rank DIMM.

Error Checking and Correcting

Error Checking and Correcting (ECC) is remains the standard technology for basic data resiliency. ECC memory

uses registered DIMMs and all error correction occurs at the memory controller.

Spare Bank

Bank 3 can be used as a spare bank of memory in the event of a DIMM failure in bank 1 or 2. Memory bank 3

acts as a failover bank and is only active in the event of a failover. All DIMMs must be the same size and rank

type for the spare bank failover to work effectively. Total system memory size will be the reported memory

amounts for banks 1 and 2. This feature can be enabled or disabled in the BIOS.

Memory Mirroring

The Dell PowerEdge 2850 supports Memory Mirroring that enables the second bank of memory DIMMs to mirror

(similar to RAID-1) the active memory bank. This memory is not hot-swappable, but does allow the server to

continue operating in the event of a DIMM failure. Only banks 1 and 2 are active in the mirroring of data. This

feature can be enabled or disabled in the BIOS.

Chipfail

Chipfail technology detects multi-bit memory errors and then rewrites the data from the failing memory chip to a

different chip. The failing chip is then disabled. This does not affect the total size of memory available for the

DIMM.

Memory Configurations

The system can operate with only one DIMM installed. If more than one DIMM is used, the memory bank must be

filled with the same type of memory. For example, when two 512MB DIMMs are installed in Bank 1, both DIMMs

must be either singe-rank DIMMs or both must be dual-rank DIMMs.


The system can operate with only one DIMM installed. If more than one DIMM is used, the memory bank must be

filled with the same type of memory. For example, when two 256MB DIMMs are installed in Bank 1, both DIMMs

must be either singe-rank DIMMs or both must be dual-rank DIMMs.

Use the following table to determine the correct DIMM configurations.

6GB 1GB 1GB 1GB 1GB 1GB 1GB





The PowerEdge 2850 supports four ranks per memory channel. Therefore, when banks one and two are fully

populated with dual ranked DIMMs, bank three DIMMs are not actually used for determining the available amount

of system memory.

BEEP CODES

The initial POST sequence may not have a any video displayed and a pattern of beep codes may be heard. For

example, one beep, followed by a second beep, and then a burst of three beeps (code 1-1-3) indicates that the

computer was unable to read the data in non-volatile random-access memory (NVRAM).

If the system loses power and beeps constantly when you turn it back on, the BIOS is probably corrupted.

LCD MESSAGES

The system's LCD can identify when the system is operating correctly or when the system needs attention. When

the bezel indicator signifies an error condition, open the bezel to see further information provided by the LCD. The

LCD can display two lines of alphanumeric characters. The display codes are presented in two color combinations:

White characters on a blue background - Information only; no action is required.

Amber characters on a black background - The system needs attention.

For faults associated with sensors, such as temperature, voltage, fans, and so on, the LCD message is

automatically removed when that sensor returns to a normal state. For example, if temperature for a component

goes out of range, the LCD will display the fault; when the temperature returns to the acceptable range, the

message is removed from the LCD display. For other faults, you must take some action to remove the message

from the display:

Clear the system event log - You can perform this task remotely, but you will lose the event history for the

system.

Chassis intrusion - When you remove the cover, the system assumes that you are servicing the bad

component; the LCD clears when you replace the cover.

Power cycle - Turn off the system and disconnect it from the electrical outlet; wait approximately 10

seconds, and then connect the power cable and restart the system.

Any of these actions will remove fault messages and return the status indicators and LCD colors to the normal

state. Messages will reappear under the following conditions:

The sensor returns to a normal state but fails again, resulting in a new system event log entry.

The system is reset and new error events are detected.

A failure is recorded from another source that maps to the same LCD message.

The table below lists the LCD status messages that can occur and the probable cause for each message.
