The following table provides companion data for the figure above relative to LED states for A/B/C SAS port expansion.
Table 8 LEDs: J1212/J1224/J1284 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.
Disk drive module
5005/4005 Series supports different disk drive modules for use in 2U and 5U enclosures. The disk drive modules used in
2U enclosures are referred to as drive carrier modules, whereas those used in 5U enclosures are referred to as a Disk
Drive in Carrier (DDIC).
Drive carrier module in 2U chassis
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.
