Dell EMC VEP4600 - Configure BIOS and boot into DiagOS

Rack mounting
When you prepare your equipment rack, ensure that the rack is grounded.
Ground the equipment rack to the same ground point the power service in your area uses. The ground path must be permanent.
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 VEP4600 installation.
Fans and airow
The VEP4600 supports an AC normal fan unit with fan airow from the I/O to the PSU.
Fan combinations
For proper ventilation, position the platform in an equipment rack or cabinet with a minimum of 5 inches (12.7 cm) of clearance around the
exhaust vents. When you install two VEP4600 platforms near each other, to permit proper airow, position the two platforms at least 5
inches (12.7 cm) apart. The fan speed varies based on internal temperature monitoring. The VEP4600 never intentionally turns o the fans.
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.
Processor power on/o button
The processor power on/o button is on the I/O-side of the platform.
• To turn on the processor, hold the button down for one second.
• To turn o the processor, hold the button down for ve seconds.
CAUTION
: Always turn o the processor correctly. For the processor to boot up correctly after a platform turn o, hold the
processor power on/o button down for ve seconds.
NOTE: Before you unplug the platform power cable, either turn o the processor using the software console or hold the
processor power on/o button down for ve seconds.
