Installing Disk DrivesTo remove drives or trays, simply push in the tab on the drive carrier to unlock the drive latch, pull the latch outto the open position as seen in Figure 6 below, and then slide the drive or tray out of the disk drive bay.Figure 6. Array Disk Drive Latch Open PositionTo install a drive or tray in an empty drive bay, simply slide the drive or tray into the empty bay with the drivelatch in the open position until the drive latch catches on the inside edge of the drive bay, then move the latch tothe closed position until it locks into place with a click.While the drive removal and insertion process is simple, there are some general guidelines to keep in mindwhen installing and removing disk drives from the array.Note: All array disk drives should be reseated before the initial startup anytime after the array is transported orshipped with the drives installed.• The disk drives in positions 00, 01, and 02 function as a system drive stripe set and must remainmounted and remain in their original positions for proper array operation.• If disk drives in positions 00, 01, or 02 must be replaced, only remove one drive at any given time.• When installing more than one drive while the system is powered on, only install one drive at a time.Wait until each drive reaches a ready state before installing the next drive.• When replacing failed disk drives, replace each drive with the same drive model.• Use dummy trays in any vacant slots to maintain proper unit air flow.Cable ConnectionsThis section describes the various connection points used for network, storage, and Fibre Channel connectivity.SAS Cable ConnectionsNEC D3/D4 Quick Start Guide 8The array SAS ports are used to connect the base unit with additional disk enclosures to expand storagecapacity. When connecting a disk enclosure to the base unit, use an SAS wide-link cable to connect each DP-IN port on the disk enclosure to the DP0 or DP1 port on the base unit. To connect more than one diskenclosure, connect the DP-IN on the next disk enclosure to DP-OUT on a previously connected disk enclosureas shown in Figure 7 below.
