QSSC-S4R Technical Product Specification System Overview

NOTE: Refer to Tables below for maximum DC loading for both AC redundant and AC non redundant
configurations.
INSTALLATION REQUIREMENTS FOR AC REDUNDANT CONFIGURATIONS
The minimum AC redundant configuration is with one PSU plugged into a main AC source, and the second PSU
plugged into a separate AC source (e.g. UPS).
The maximum AC redundant configuration is with two PSU plugged into a main AC source and two other PSU’s
plugged into a separate AC source (e.g. UPS)
Table 26. Maximum DC Loading Requirements
1 +1 (2 PSU) 830W Yes DC Redundancy
2+2 (4 PSU) 1580W Yes DC Redundancy
INSTALLATION REQUIREMENTS FOR AC NON REDUNDANT CONFIGURATIONS
For systems not requiring AC redundancy, the power supply subsystem can be installed with up to 4 PSU’s. The PSU’s
can be connected to a single or multiple AC sources.
Table 27. Maximum DC Loading Requirements
1+0 (1 PSU) 830W No DC Redundancy
2+0 (2 PSU’s) 1580W No DC Redundancy
1+1 (2 PSU’s) 830W Yes DC Redundancy
3+0 (3 PSU’s) 2300W No DC Redundancy
2+1 (3 PSU’s) 1580W Yes DC Redundancy
3+1 (4 PSU’s) 2300W Yes DC Redundancy
NOTE: Quanta does not validate 1+1 (2 PSU) or 2+1 (3 PSU) with DC Redundancy scenarios. ONLY 2+2 or
3+1 (4 PSU) is supported for DC Redundancy.
Three power supply module are capable of handling the maximum power requirements for a fully configured QSSC-
S4R Server System, which include the following:
x Four processors
x 512GB of memory
x Eleven PCIe add-in cards (including the SAS RAID riser)
x Eight hard disk drives
x One optical drive
x One tape drive
