Bonding

All structural sections of the HP POD 240e NA are bonded by connecting all metallic, non-current carrying items throughout the HP POD 240e NA to protect from electric shock. If all steel-to-steel areas are bonded to one another, each object then has the same electrical potential which ultimately dissipates any high voltage or shock across the entire HP POD 240e NA, minimizing any effects from a lightning strike, per NFPA 70 in accordance with NEC (NA) and IEC (EMEA and APJ).

Lightning protection

The HP POD 240e NA structure and internal components are all bonded together. A common grounding electrode conductor connection point is provided. Proper bonding and grounding of the HP POD 240e NA minimizes the effects of a lightning strike. A surge protection device is provided on the HP POD 240e NA input connection to protect the HP POD 240e NA electrical system from voltage transients. If your site is in an area that is subject to frequent lightning strikes, the HP POD 240e NA must be protected in accordance with NFPA 70 (NA) and IEC (EMEA and APJ). HP recommends that you contact a certified lightning protection consultant.

Capacities

Each HP POD 240e NA is unique and the specific power and cooling capacities vary for each POD that uses Adiabatic cooling. For specific capacity information, see your HP Performance Optimized Datacenter 240e NA Customized Supplement.
