CHAPTER 3: PREPARING THE SITE
3.5 FANS AND AIRFLOW
The EMS100G-32 fans support normal airflow (from the I/O side to the PSU side).
Fans
Installation of the fans is done as part of the factory install based on stock keeping units (SKU) type. The EMS100G-32 supports
the following configuration:
AC PSU with fan airflow from the I/O to the PSU
NOTE: Use a single type of airflow fan in your switch. Do not mix reverse and normal airflows in a single EMS100G-32 chassis.
For proper ventilation, position the EMS100G-32 in an equipment rack or cabinet with a minimum of 5 inches (12.7 cm) of clearance
around the exhaust vents.
3.6 POWER
To connect the chassis to the applicable power source, use the appropriate power cord with the EMS100G-32. 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 EMS100G-32 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 +158° F (-40 to +70° 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 and 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.
