Drive Carrier Module; Leds: J1212/J1224 Expansion Activity States - Seagate RealStor 5005 Series Hardware Installation

The following table provides companion data for the figure above relative to LED states for A/B/C SAS port expansion.
Table 7 LEDs: J1212/J1224 expansion activity states
Condition
No cable present
Cable present: all links up/no activity
Cable present: all links up/with aggregate port activity
Critical fault: Any fault causing operation of the cable to cease or fail to start (e.g.,
over current trip).
Non-critical fault: any fault that does not cause the connection to cease operation
(e.g., not all links are established; over temperature).
IMPORTANT: RBOD/EBOD configurations:
• When the expansion module shown above
storage, its middle HD mini-SAS expansion port ("B") is disabled by the firmware. See also
• The Ethernet port on the expansion module is not used in RBOD/EBOD configurations, and is disabled.

Drive carrier module

The drive carrier module comprises a hard disk held by a carrier.
• Each 2U12 drive slot holds a single low profile 1.0-inch high, 3.5-inch form factor disk drive in its carrier. The disk
drives are horizontal. A 2.5" to 3.5" carrier adapter is available to accommodate 2.5" disk drives.
• Each 2U24 drive slot holds a single low profile 5/8-inch high, 2.5-inch form factor disk drive in its carrier. The disk
drives are vertical.
The carriers have mounting locations for:
• Direct dock SAS drives.
A sheet steel carrier holds each drive, which provides thermal conduction, radio frequency, and electro-magnetic
induction protection, and physically protects the drive.
The front cap also has an ergonomic handle which gives the following functions:
• Secure location of the carrier into and out of drive slots.
• Positive spring-loading of the drive/midplane connector.
The carrier can use this interface:
• Dual path direct dock Serial Attached SCSI.
