HP BladeSystem c-Class Site Planning Guide

Power requirements and considerations 45
• N+N redundant, 5kVA enclosure configuration with 24A single-phase PDU
HP BladeSystem c7000 Enclosure three-phase AC configuration
To cable the enclosure using a three-phase AC configuration:
1. The AC power cables are already attached to the enclosure.
2. Connect the AC power cables to the AC power source.
3. Turn on the AC circuit breakers that power the power cables installed in the enclosure.
When the enclosure powers up for the first time, it might take up to 5 minutes before all server blades are
initialized and recognized by the Onboard Administrator. The time it takes to complete initialization
depends on the number of server blades configured in the enclosure. For example, a full enclosure of 16
server blades might take 5 minutes to power up, while an enclosure with fewer server blades might take
less time.
