NonStop NS2400 Series Planning Guide

AC Power Feeds
Power can enter the NonStop NS2400 series system from either the top or the bottom rear of the
modular cabinets, depending on how the cabinets are ordered from HP and how the AC power
feeds are routed at the site. NonStop NS2400 series system cabinets can be ordered with the AC
power cords for the PDU installed either:
• Top: Power and I/O cables are routed from above the modular cabinet.
• Bottom: Power and I/O cables are routed from below the modular cabinet.
