ATI Graphics Controller
The X7DBU features an integrated ATI video controller based on the ES1000 graph-
ics chip. The ES1000 was designed specifi cally for servers, featuring low power
consumption, high reliability and superior longevity.
Other Features
Other onboard features that promote system health include onboard voltage moni-
tors, a chassis intrusion header, auto-switching voltage regulators, chassis and CPU
overheat sensors, virus protection and BIOS rescue.
1-3 Server Chassis Features
The 6015B-UR/6015B-NTR is built upon the SC815TQ-R650U chassis while the
6015B-U/6015B-NT is built upon the SC815TQ-560U chassis. The following is a
general outline of the main features of both chassis.
System Power
The SC815TQ-R650U features a redundant 650W power supply consisting of two
power modules. The system does not need to be shut down when replacing or
removing a single power supply module. The SC815TQ-560U features a single
560W power supply module. The system must be shut down when replacing or
removing this power supply module.
SATA Subsystem
The SC815TQ-R650U/SC815TQ-560U chassis was designed to support four hot-
swap SATA hard drives. Note: In the 6015B-NTR/6015B-NT, SATA drives are
connected to the onboard SATA ports.
PCI Expansion Slots
6015B-UR/6015B-U: A riser card on the right side of the chassis can support either
one PCI-X 133 card or one PCI-E x8 card. The left side supports a UIO card and
one PCI-E x8 card.
6015B-NTR/6015B-NT: A riser card on the right side of the chassis can support
either one PCI-X 133 card or one PCI-E x8 card. The left side supports two PCI-E
x8 cards. See section 5-6 for details. (Right and left refer to the side when viewed
from the front of the system. The 6015B-NTR/6015B-NT does not support a UIO
card.)
