Things to Know – E2600 Controller-Drive Tray
On the E2600 controller-drive tray, each controller has a pair of levers with handles for removing the controller
from the controller-drive tray. One of these handles on each controller is located next to a host connector. The close
spacing between the handle and the host connector might make it difficult to remove a cable that is attached to the
host connector. If this problem occurs, use a flat-blade screwdriver to push in the release component on the cable
connector.
„
The E2600 controller-drive tray supports both the DE1600 drive tray and the DE5600 drive tray for expansion.
„
The maximum number of drive slots in the storage array is 96 (expandable to 192
)
, including the 12 or 24 drive
slots in the controller-drive tray. Exceeding 96 (or 192) drive slots makes the storage array invalid. The
controllers cannot perform operations that modify the configuration, such as creating new volumes.
„
Each controller has one dual-ported SAS expansion connector to connect to the drive trays.

NOTE To maintain data access in the event of the failure of a controller, an ESM, or a drive channel, you must
connect a drive tray or a string of drive trays to both drive channels on a redundant path pair.
ATTENTION Potential damage to equipment (Network Telecommunications Equipment (NEBS) Ethernet
cable installations only)
– The intra-building port(s) (Ethernet maintenance ports) of this equipment is suitable for
connection to intra-building or unexposed wiring or cabling only. The intra-building port(s) of this equipment must
be metallically connected to interfaces that connect to the Outside Plant (OSP) or its wiring. These interfaces are
designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and
require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in
order to connect these interfaces metallically to OSP wiring. The cable shall be shielded Twisted Pair (STP) and must
be grounded at both ends to meet the intra-building lightning requirements from section 4.6.9.2 of GR-1089-CORE,
