Reduced air Flow – Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
To prevent fires, and damage to rack equipment and supply wiring, make sure that the
rated load of the power branch circuit is not exceeded. Equipment nameplate ratings
should be used when addressing this concern. For more information on installation and
wiring of power-related facilities, contact your electrician or local power company.
To prevent electrical shock, connect all rack and rack support equipment to the same
electrical circuit of the building wiring. If you are unsure, check the building wiring to
avoid remote earth conditions.
For safe operation, only connect the equipment to a building supply that is in accordance
with current wiring regulations in your country. In the USA those wiring standards are
regulated by Underwriter Laboratories (UL); in the U.K. by the Institution of Electrical
Engineers, (IEE) and in Canada by the Canadian Standards Association (CSA).
Some locations within the server have high voltage and therefore are very
dangerous. To avoid risk of electric shock, turn off all server power and
disconnect power cables before working inside the server unit.
The main power of your server is turned off by turning off the power source to the
server or removing the power cable.
Before touching the parts in the server, wait for at least 10 to 15 seconds until
residual voltage is discharged.
Online maintenance – During and after servicing, do not leave the server door open
unless necessary to perform servicing.
