Getting Started
This chapter describes how to set up your server and get st arted.

Make sure you have everything
Make sure you have everything
Be sure to check the contents of the package against your purchase
order . If any items are missing or damaged, please notify your
T oshiba dealer i mmediately.
NOTE: The purchase order provides a listing of all standard
accessories and their quantities. If you purchased the server
with optional devices, the optional devices are also
deliveredwith the standard accessories listed. In such a case,
however, it is possible that the quantities of some
accessories, e.g., brackets, do not agree with those specified
on the list, because they have already been used to fix the
optional devices. In contrast, if an expansion slot cover etc.
has been removed from the server to install an optional
device instead, the removed expansion slot cover is delivered
with the server as an accessory.
[Example]
If you purchase the server with a built-in DAT (Digital Audio
Tape) deck, all accessories of the DAT deck are also
delivered with the server as additional accessories, while the
device bay spacer, which was removed from a 5.25-inch slot
to install the DAT deck, is delivered as an accessory.

Before connecting the power cable to your serv er , remo ve the
front door panel and the side panel to ensure that all components
are installed correctly.
See “Removing and replacing the server panels” on page21.

Installing optional internal devices
Installing optional internal devices
Install all optional device s, if any, before setting up the server.
See “Installing and removing optional de vices” on page 42.
If you have no experie nce installing or remo ving computer
hardware devices, or if the job seems dif f icult, always consul t
T oshiba Technical Support or your T oshiba dealer . (You will be
charged a service fee).

Installing the server
Environmental considerations
WARNING: If debris or liquid gets in to the server, shut it
down immediately, turn off the power button, and unplug the
power cable from the AC outlet. Failure to do so could result
in a fire or shock. Contact Toshiba Technical Support or your
Toshiba dealer to ask for service.
Do not install the server on an unsteady or slanted surface,
otherwise the server may fall over, causing injury.
Do not install the server in a dusty place. Dust can cause
short circuits that could lead to fire or smoke damage.
Do not install the server where it can be exposed to rain or
mist. Rain and mist could cause a fire or shock hazard.
Do not install the server in a poorly ventilated place. Blocking
air vents or installing the server where heat from the server
cannot be discharged will cause the temperature inside the
server to rise, causing risk of a fire.
Do not install the server where it can be exposed to corrosive
gases or salty air, this could cause the server to produce
smoke.
CAUTION: Do not install the server where it can be exposed
to vibration or shock, this could cause the server to topple
over, causing injury.
Do not install the server where the temperature can rise, for
example, exposure to direct sunlight or near to a heater, this
can cause the temperature inside the server to rise, causing
the possibility of fire in the worst case.
Getting Started
Installing the server
$
Install the server in a clean, dust-free, and well- ventilated
place.

- Near any devices that generat e a strong magnetic f ield or
produce radio frequency noise, such as a radio, TV, large
motor, high-fr equency electric apparatus, air conditioner ,
large fan, or loudspeaker.
- Where the temperature and humidity change constantly, near
an air-conditioning vent, cooling fan, heater or heat source.
- Near liquids or corrosiv e chemicals.

Operate the server under the follow ing temperature and
humidity conditions:
- Ambient temperature: 10 to 35°C (50 to 95°F)
- Relative humidi ty: 30 to 80%Rh (no condensation)
CAUTION: To avoid damage from condensation when the
room temperature is too high or too low, switch on the server
about an hour after the room temperature falls within a range
of 10 to 35
Avoid exposing the server to condensation during use and
storage.
