Power
To connect the switch to the applicable power source, use the appropriate power cable. An AC power cable is included with
each PSU.
When installing AC or DC switches, follow the code requirements appropriate for your country or region. For example, in the
U.S., follow
National Electrical Code ANSI/NFPA 70 and in Europe follow IEC60364 .
The switch powers-up when the power cable connects the switch to the power source. For more information, see Power
supplies .
CAUTION: To avoid equipment damage, always disconnect the power cables before you service the power supply
slots. The switch has multiple power cables. Before servicing, disconnect all power cables.
CAUTION: On an AC switch, the main power disconnect device is the power supply cable. Ensure that the socket
outlet is located or installed near the equipment and is easily accessible.
NOTE: Redundant AC power requires high-line 200 VAC to 240 VAC. Using low-line 120 VAC does not provide redundancy
for the switch.
NOTE: PSU airflow must match the airflow direction of the fans. The fans ship preinstalled with airflow from the I/O to the
PSU. Optionally, you can order and install fans with airflow from the PSU to the I/O.
NOTE: You do not see module LEDs when the switch power up in ONIE as the software controls the modules.
Storing components
If you do not install your S5448F-ON switch and components immediately, properly store the switch and all components using
these guidelines:
● Storage location temperature must remain constant. The storage range is from -40°C to 70°C (-40° to 158°F).
● Store on a dry surface or floor, away from direct sunlight, heat, and air conditioning ducts.
● Store in a dust-free environment.
CAUTION: ESD damage can occur when components are mishandled. Always wear an ESD-preventive wrist
or heel ground strap when handling the S5448F-ON switch and accessories. After you remove the original
packaging, place the S5448F-ON switch and components on an anti-static surface.
