Intel® RAID Controller RS2BL080 Technical Product Specification 
 
 
Revision 1.0
 
 
Intel order number E64388-001 
18 
Feature 
Intel® RAID Controller RS2BL080 
Serial port 
4-pin serial debug (requires transceiver) 
Compatible devices 
32 physical devices, 64 logical drives, mixed capacity drives, SAS and SATA hard drives, and 
non-disk devices including expanders. 
Firmware 
8 MB in flash ROM 
2.5  Electrical Characteristics  
The PCI Express* Specification requires that the 12-V rail and the 3.3-V rail have a voltage 
tolerance of 8% and 9% respectively. The amount of power that an adapter card can use is also 
limited. 
All power is supplied to the Intel
®
 RAID Controller RS2BL080 through the PCI Express* 3.3-V 
rails and the 12-V rails. The on-board switching regulator circuitry, operating from these rails, 
provides the necessary voltage. The following states determine the typical current consumption 
of the controller: 
ƒ 
State 1: Battery is charging 
ƒ 
State 2: Battery is full 
ƒ 
State 3: Battery is discharging 
The supply voltages are 12 V ± 8 percent from the PCI edge connector only and 3.3 V ± 9 
percent from the PCI edge connector only. The following table lists the power supply for the 
RAID controller for each state at the different voltages:
