Chassis power redundancy modes overview

The
VELOS
 chassis supports these power configuration modes:
No redundancy
The chassis has enough working power supply units (PSUs) to support all installed components.
N+1 redundancy
The chassis has more working PSUs than are required to support all installed components. The system will remain fully functional if a single PSU fails.
N+N redundancy
The chassis has twice as many working PSUs than are required to support all installed components. This configuration is typically used in DC installations with two independent DC power buses. The system will remain fully functional if half of the working PSUs fail (or if one of the facility’s two DC buses fails).
In the event that there is insufficient power to support all installed components, the system provides a warning. These warnings are configurable.

Power redundancy provisioning

CX410 supports one to four AC or DC power supply units (PSUs). Each slot is provisioned to draw up to 400W; therefore, one PSU can support two blade slots with no redundancy. This table shows some of the possible blade and PSU redundancy configurations.

AC power requirements

When working with an AC-powered VELOS platform, it is important to understand the AC power options and requirements.

AC power cables

The power cable supplied with the hardware is a 220V high-line input cable. This type of cable requires a NEMA 6-20R wall outlet or a region-specific equivalent. Region-specific power cables are available from F5.
The power cables included with this unit are for exclusive use with this unit and should not be used with other electrical appliances.

AC power specifications - VELOS CX410 Series

The actual amount of power draw from the AC source depends on the type and number of blades, and the power supply AC source voltage and redundancy configuration.

DC power requirements

When working with a DC-powered VELOS CX410 Series platform, it is important to understand the DC power options and requirements.
The platform supports up to four hot swappable DC power supplies. One power supply powers a chassis that contains zero to four blades, with no redundancy. Four power supplies power a chassis with any blade configuration, with full redundancy.

DC power specifications - VELOS CX410 Series

The actual amount of power draw from the DC power source depends on the type and number of blades and the redundancy configuration.
This table shows several possible configurations, and the typical and maximum power draw measured at the output of the power supply (at an input voltage of 48 VDC).
F5® recommends that you add 10% to the numbers in the table due to conversion loss in power supplies when you are provisioning power and cooling.
