Configuration Guidelines  
Use the following guidelines to install and cable or reconfigure your StorEdge A3500  
system.  
The part number for the 12 meter SCSI host cable is 530-1886-xx.  
Do not exceed a SCSI bus length of 25 meters (82 feet).  
Make sure that the last StorEdge A3500 controller module in any daisy chain has  
a total of two terminators—one in each SCSI OUT port.  
If you are adding a controller module to an already existing configuration, halt all  
activity on the SCSI bus before removing any SCSI cables.  
Once you finish cabling the devices and powering on, reboot the system by  
typing boot -rat the okprompt before beginning any SCSI bus activity.  
Perform a system check to make sure that SCSI connections are secure. Look for  
fault LEDs on the hardware or error messages in the RAID Manager GUI.  
Note – Refer to your server and rack documentation for instructions on grounding  
the StorEdge A3500 expansion cabinet.

Ultra 2 Host System Power Connection  
Requirement  
You can connect a controller module to an Ultra 2 host system; however, you must  
connect the power cord of the Ultra 2 host to one of the AC power sequencers in the  
expansion cabinet that contains the controller module.  
Note – The RAID Manager 6.22 software does not support Ultra 2 host systems.  
You need to order one of the following power cords depending on the type of power  
sequencer in the expansion cabinet (FIGURE 1-5):  
Ultra Enterprise™ expansion cabinet and StorEdge expansion cabinet—  
part number 530-2197  
1422 mm/ 56-inch Data Center expansion cabinet—part number 180-1189 (United  
States) or 180-1190 NEMA (European)  
Caution – Failure to connect the power cord correctly as described here may cause  
excessive ground current that could damage the system.

See the documentation that came with the expansion cabinet.  
2. Route the power cable from the Ultra 2 host under the expansion cabinet frame on  
the same side as the power sequencer.  
3. Connect the power cord from the Ultra 2 host into the top power connector of  
either power sequencer (FIGURE 1-5).  
The power connectors are located on the other side of the power sequencer from the  
main switch.  
4. Reassemble the expansion cabinet.  
See the documentation that you received with the expansion cabinet.

Configuration Guidelines  
Use the following guidelines to install and cable or reconfigure your StorEdge  
A3500FC system.  
Caution – The onboard SOC+ on the I/ O board is not qualified yet to work with  
the StorEdge A3500FC controller module.  
Caution – At this time, only single port connection is qualified on the dual-ported  
host bus adapter card.  
The part number for the 15 meter FC-AL host cable is 595-3379-xx; the Marketing  
part number is X978A.  
Do not exceed a fiber-optic cable length of 500 meters (1640.5 feet).  
Install 16-bit, differential terminators to both HOST IN connectors on the back of  
the controller module (FIGURE 2-1).

Once you finish cabling the devices and powering on, reboot the system by  
typing boot -rat the okprompt before beginning any SCSI bus activity.  
Perform a system check to make sure that SCSI and fiber-optic cable connections  
are secure. Check for fault LEDs on the hardware or error messages in the RAID  
Manager GUI.  
Note – Refer to your server and rack documentation for instructions on grounding  
the StorEdge A3500FC expansion cabinet.

Note – No other type of fibre channel device should share the same loop or hub  
connected to the A3500FC controller module.  
Each controller that is connected to a hub must have a unique loop ID. Whenever  
you add a second controller to a hub, make sure that the loop ID of the controller  
being connected is different from the loop ID of any other controller currently  
connected to the same hub.  
Refer to Section 2.3 “Setting the Loop ID” on page 2-13 for instructions on setting the  
loop ID of a controller.  
Caution – Ensure that the controller module IDs are set so that each hub is  
connected to A and B controller canisters.

2.3  
Setting the Loop ID  
This section explains how to set the loop ID of a controller that is connected to a  
hub.  
Tools and equipment needed:  
Needlenose pliers  
Jumpers (supplied with the StorEdge A3500/ A3500FC unit)  
Antistatic wrist strap  
Every device attached to a SCSI or FC-AL bus must have a unique controller module  
ID number in order to communicate. The factory default ID settings for controller A  
and B are ID 5 and ID 4, respectively.  
Note – Do not configure more than four controller modules on the same loop.  
1. Locate the 16 pins on the rear of the FC-AL controller module (FIGURE 2-8).  
The eight pins on the right determine the host ID for controller 1(A); the pins on the  
left determine the ID for controller 2(B).  
2. Wearing the antistatic wrist strap, install jumpers on the pins as shown in  
FIGURE 2-8.  
If necessary, use the needlenose pliers to remove the jumpers.

This section contains information about SCSI and power connections for one  
StorEdge A3500 with two StorEdge D1000 disk arrays.  
Note – The 1x2 configuration is not qualified on the A3500FC controller module.  
In the 1x2 configuration, the controller module can be either on top of or below the  
two disk arrays. Both configurations are described in this section.  
Tip – Do not place the controller module at the bottom of the rack because the  
controller board diagnostic LEDs will not be visible.

Connections Between Power Sequencers  
The front and rear power sequencers in the 2x7 expansion cabinet and the 1x8  
expansion cabinet must be interconnected. Make sure an interconnect cable (part  
number 530-2325) is connected between the OUT on the front sequencer in the 2x7  
expansion cabinet and the IN on the front sequencer in the 1x8 expansion cabinet  
(FIGURE 3-22). Make sure that the rear sequencers are likewise connected.

3.5.3  
Connections to AC Power Sources  
Each of the AC power cords connected to the expansion cabinets should be on  
independent circuit breakers.  
To ensure proper redundancy, if independent circuit breaker boxes or AC power  
sources are used, make sure that power cords from the same expansion cabinet are  
connected to different circuit breaker boxes or AC power sources.  
Caution – Ensure that the second rack will not lose power before the first rack loses  
power. Data loss is likely to occur if this happens. Do not configure the 3x15  
expansion cabinets as shown in FIGURE 3-23 and FIGURE 3-24. Consult with an  
electrician if you do not understand the schematics in these figures.
