CHAPTER 3: PREPARING THE SITE
3.5 FANS AND AIRFLOW
The EMS10G12 fans support two airflow options—normal and reverse.
Installation of the fans is done as part of the factory install,. The EMS10G12 supports the following configuration:
AC PSU with fan airflow from the I/O to the PSU
For proper ventilation, position the EMS10G12 in an equipment rack or cabinet with a minimum of 5 inches (12.7 cm) of clearance
around the exhaust vents. The fan speed varies based on internal temperature monitoring. The EMS10G12 never intentionally turns
off the fans.
3.6 POWER
To connect the chassis to the applicable power source, use the appropriate power cord with the EMS10G12. An AC power cord is
included with the switch.
When installing AC switches, follow the requirements of the National Electrical Code, ANSI/NFPA 70 where applicable.
The switch is powered-up as soon as the power cord is connected between the switch and the power source.
CAUTION: Always disconnect the power cable before you service the power supply slots.
CAUTION: Use the power supply cord as the main disconnect device on the AC switch. Make sure that the socket outlet is located/
installed near the equipment and is easily accessible.
3.7 STORING COMPONENTS
If you do not install your EMS10G12 and components immediately, properly store the switch and all optional components
by following these guidelines:
Storage location temperature must remain constant. The storage range is from -40 to +149° F (-40 to +65° C).
Store on a dry surface or floor, away from direct sunlight, heat and air conditioning ducts.
Store in a dust-free environment.
NOTE: ESD damage can occur when components are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the switch and its accessories. After you remove the original packaging, place the switch and its components
on an anti-static surface.
