Safe handling precautions
High voltage
Danger of electric shock - high voltages exist within this
equipment. Only an approved and qualified service
engineer is permitted to remove the covers of this
equipment. Failure to comply may result in death or
serious injury.
When servicing, always isolate the mains power supply
and remove all three mains input cables after powering
down the server, thereby removing the danger of electric
shock from the server.
High temperature
Danger of burns - the temperature on the surface of the
power supply module maybe around 48°C (120°F) to
60°C (140°F) depending on the ambient temperature.
Wear protective gloves as needed.
Always take care when handling the server immediately
after it has been powered down, as the covers and chassis
in close proximity to the power supply area may be hot to
the touch.
Heavy weight
Danger of injury - this equipment weighs
approximately 42 kg. Do not attempt to lift the unit
unaided. Seek assistance.
Always seek assistance when lifting the server unit or
removing it from a rack. The server is heavy and requires
special handling.
Electrostatic discharge (ESD)
precautions
This equipment contains electrostatic sensitive devices.
Only qualified persons familiar with appropriate ESD
handling precautions and procedures should remove
the covers or the hard disk drives (HDDs). Failure to
observe these procedures may result in damage to this
equipment.
The server unit contains components (including printed
circuit boards and hard disk drives) that are sensitive and
susceptible to damage from electrostatic discharge (ESD).
Static generated by your body, your clothes, or by work
environment, can cause immediate or latent damage to the
these components, which may subsequently fail. Avoid the
possibility of static build-up by ensuring that you are
earthed at all times. You can do this by using the handling
methods outlined below.
Anti-static handling precautions are recommended:
• when the covers of the server are removed for
servicing and internal components are exposed.
• when replacing any parts on the server, with the power
on or off.
• when inserting or removing a USB memory device
with the server power on.
• when pushing the eject button on the DVD/CD drive
with the server power on.
Anti-static handling
The following methods are recommended to help prevent
damage to the server by ESD:
• use an anti-static wrist or foot strap. Attach the
relevant end of the strap to the server metal chassis or
appropriate earthing point, and attach the other end to
your wrist or ankle. Refer to the instructions provided
with the strap.
• place items on an anti-static mat (or equivalent) . A
permanent anti-static mat, or disposable mat shipped
with replacement parts, must be earthed in the same way
as a wrist strap.
• use an anti-static bag to protect replacement parts for
shipping or handling.
• hold cards by the edges to avoid touching conducting
parts and pcb tracks.
• touch the lid/chassis of the server every 30 seconds or
so, when handling sensitive components.
