Equipment Rack Specifications

Table 3-1 8-Slot Line Card Chassis Component and Power Specifications (continued)

	Note Proper grounding is also required at the site to
	ensure that equipment is not damaged by
	lightning or power surges.
Power Redundancy (2N)
DC	Three “A” battery plant feeds required for one PDU,
	and three “B” battery plant feeds required for the other
	PDU.
AC (Delta or Wye 3-phase)	Two independent Delta or Wye 3-phase power sources
	required, one for each PDU.
