Connector Details

CN1: Mini-SAS connector to Host

CN4: Backplane ID setting jumper

CN5: Fan failure/HDD access LED output connector (to LED board)

Jumper Settings

CN4 sets the backplane ID (see illustration below). Each backplane must have a unique ID number and the backplane physically nearest the bottom of the system must have ID #1.

Pin CN4 Backplane ID
1-2	#1
3-4	#2
5-6	#3
7-8	#4
9-10	#5
11-12	#6

LED Module

For configurations using the LED module (part 80H033215-005 VER:A2):

Connect the daisy chain cable to CN5 on each backplane and then to CN2 on the LED module itself.
Ensure that the jumper switch setting on the LED module is set to the defaults as indicated by ** in the table below.


SW-1: DIP1 - DIP4	Function	ON	OFF
1	Monitoring BP Fan Q'ty Setting	5	4**
2	Monitoring Temperature Setting	65° C	55° C**
3	SATA HDD Spin Up	Simultaneously ON	Sequential Spin Up**
4	Fan Alarm Setting	Enable**	Disable

	For 2U RM21508B	ON	OFF
	For 3U RM31212B	OFF	ON
	For 4U RM41416B	ON	ON

Disk Carrier LEDs

The Chenbro 4-drive mini-SAS backplane for RM series includes an SGPIO processor device which manages the backplane LEDs. The RAID controller communicates with the SGPIO device using dedicated signals within the mini-SAS link cable.

Note: Ensure you use a mini-SAS to mini-SAS link cable type which connects the sidebands signals.

Activity LED

SATA drives: LED will illuminate green when the drive is accessed
SAS drives: LED will illuminate green when idle and blink off when accessed (normal SAS drive behaviour)

Drive fault condition

SAS drives: LED is solid amber
SATA drive: LED is solid red

Identify drive (Adaptec Storage Manager)

SAS drives: LED blinks amber
SATA drives: LED brinks red

Adaptec Storage Manager

Adaptec Storage Manager will display each 4-slot mini-SAS backplane as a separate enclosure and will report an Adaptec SGPIO SEP device corresponding to the Chenbro enclosure processor device.

Note: Adaptec Storage Manager displays the first disk slot on the first backplane as “slot 0”.
