The “chassis manual” download for SC811i-300B (http://www.supermicro.com/products/chassis/1U/811/SC811i-300.cfm) only lists SC811TQ-520 SC811TQ-280, SC811S-520, SC811S-280, SC811i-520 and SC811i-280. I didn’t see the -300 part number listed. Is this the correct documentation? If not could you send me a link to the correct documentation?
Yes, actually it is the same series chassis (TQ for SATA/SAS hard drive support). The (S for SCSI hard drives support) and the (I version for IDE hard no hot swap hard drive trays support). The only difference is power supply wattages.
