1-3 Server Chassis Features
The 1028UX-CR-LL1/1028UX-CR-LL2 is built upon the SC119UTS-R750 chassis.
The following is a general outline of the main features of the chassis.
System Power
The chassis features a redundant 750W power supply consisting of two redundant,
hot-plug power modules, so one may be replaced without powering down the
system.
Hard Drives
The default chassis supports ten hot-swap 2.5" drives bays, which consist of eight
SAS 3.0 drives and two SATA 3.0 drives.
PCI Expansion Slots
Riser cards and brackets are required to install expansion cards. The system has
two pre-installed riser cards to support three PCI expansion cards as follows. The
RSC-R1UW-2E16 riser for two PCI-E 3.0 x16 add-on cards and the RSC-R1UW-
E8R riser for one PCI-E 3.0 x8 add-on card.
Front Control Panel
The chassis front control panel provides system monitoring lights and power control
buttons. See Chapter 3 for details.
Cooling System
The system has an innovative cooling design that features four sets of 4-cm
counter-rotating fans located in the middle section of the chassis. Fan speed may
be controlled by IPMI to respond to fluctuations in system temperature.
