Remove

 

items

 

from

 

your

 

shirt

 

pocket,

 

such

 

as

 

pens

 

and

 

pencils,

 

that

 

could

 

fall

 

into

 

the

 

server

 

as

 

you

 

lean

 

over

 

it.

 

v

   

Avoid

 

dropping

 

any

 

metallic

 

objects,

 

such

 

as

 

paper

 

clips,

 

hairpins,

 

and

 

screws,

 

into

Handling

 

static-sensitive

 

devices

 

Attention:

  

Static

 

electricity

 

can

 

damage

 

the

 

server

 

and

 

other

 

electronic

 

devices.

 

To

 

avoid

 

damage,

 

keep

 

static-sensitive

 

devices

 

in

 

their

 

static-protective

 

packages

 

until

 

you

 

are

 

ready

 

to

 

install

 

them.

 

To

 

reduce

 

the

 

possibility

 

of

 

damage

 

from

 

electrostatic

 

discharge,

 

observe

 

the

 

following

 

precautions:

 

v

   

Limit

 

your

 

movement.

 

Movement

 

can

 

cause

 

static

 

electricity

 

to

 

build

 

up

 

around

 

you.

 

v

   

The

 

use

 

of

 

a

 

grounding

 

system

 

is

 

recommended.

 

For

 

example,

 

wear

 

an

 

electrostatic-discharge

 

wrist

 

strap,

 

if

 

one

 

is

 

available.

 

Always

 

use

 

an

 

electrostatic-discharge

 

wrist

 

strap

 

or

 

other

 

grounding

 

system

 

when

 

working

 

inside

 

the

 

server

 

with

 

the

 

power

 

on.

 

v

   

Handle

 

the

 

device

 

carefully,

 

holding

 

it

 

by

 

its

 

edges

 

or

 

its

 

frame.

 

v

   

Do

 

not

 

touch

 

solder

 

joints,

 

pins,

 

or

 

exposed

 

circuitry.

 

v

   

Do

 

not

 

leave

 

the

 

device

 

where

 

others

 

can

 

handle

 

and

 

damage

 

it.

 

v

   

While

 

the

 

device

 

is

 

still

 

in

 

its

 

static-protective

 

package,

 

touch

 

it

 

to

 

an

 

unpainted

 

metal

 

surface

 

on

 

the

 

outside

 

of

 

the

 

server

 

for

 

at

 

least

 

2

 

seconds.

 

This

 

drains

 

static

 

electricity

 

from

 

the

 

package

 

and

 

from

 

your

 

body.

 

v

   

Remove

 

the

 

device

 

from

 

its

 

package

 

and

 

install

 

it

 

directly

 

into

 

the

 

server

 

without

 

setting

 

down

 

the

 

device.

 

If

 

it

 

is

 

necessary

 

to

 

set

 

down

 

the

 

device,

 

put

 

it

 

back

 

into

 

its

 

static-protective

 

package.

 

Do

 

not

 

place

 

the

 

device

 

on

 

the

 

server

 

cover

 

or

 

on

 

a

 

metal

 

surface.

 

v

   

Take

 

additional

 

care

 

when

 

handling

 

devices

 

during

 

cold

 

weather.

 

Heating

 

reduces

 

indoor

 

humidity

 

and

 

increases

 

static

 

electricity.

Removing

 

the

 

cover

 

Important:

 

Before

 

you

error

 

code

 

is

 

displayed,

 

indicating

 

that

 

an

 

operating

 

system

 

was

 

not

 

found

 

but

 

the

 

server

 

is

 

otherwise

 

working

 

correctly.
