Install Guide

Platform ground
Dell EMC recommends you ground your platform. Use the VEP4600 in a common bond network (CBN).
Connect the grounding cables as described in the VEP4600 installation section. .
Fans and airflow
The VEP4600 supports fan units with airflow from front to back.
Fan combinations
The fan speed varies based on internal temperature monitoring. The VEP4600 never intentionally turns off the fans.
Table 5. Ventilation specifications
Ventilation clearance requirements
Horizontal (table top) placement Minimum of 5 inches (12.7 cm) of clearance between the unit's
exhaust vents.
Vertical (rack) placement Minimum of 5 inches (12.7 cm) of clearance from the back of the
vertically racked unit's exhaust vents to a wall or enclosure.
For more information, see Fans.
Power
Connect the platform to the applicable power source using the appropriate power cable. An AC power cable is included with the platform.
When installing an AC platform, follow the requirements of the National Electrical Code, ANSI/NFPA 70, where applicable.
The platform is powered-up when you connect the power cable between the platform and the power source. For more information, see
Power supplies.
CAUTION:
Always disconnect the power cable before you service the power supply slots. The platform has multiple
power cables. Before servicing, ensure that all power cables are disconnected.
CAUTION: Use the power supply cable as the main disconnect device. Ensure that the socket-outlet is located and
installed near the equipment and is easily accessible.
ACPI on/off button
The ACPI (Advanced Configuration and Power Interface) on/off button is on the I/O-side of the platform.
ACPI button options:
• Short push:
○ Sends ACPI power event to the Operating System (OS.)
NOTE:
Response depends on configuration of how the OS is booted-up when it receives a ACPI power event. The
response may ignore the button push or shutdown the system.
• Long push:
○ Sends ACPI power event to the OS and immediately puts the CPU to sleep. When CPU is in sleep state, a short push brings the
CPU out of sleep and reboots the system.
CAUTION:
Always turn off the processor correctly. Hold the ACPI on/off button down for five seconds to boot-up after
a correct processor shutdown.
NOTE: Before you unplug the platform power cable, either turn off the processor using the software console or hold the
ACPI on/off button down for five seconds.
