Uninterruptible power supply
Also available with a three- year warranty, including batteries, Dell UPS (uninterruptible power supply)
backup systems are available in line- interactive and online models in tower and rack- mount styles.
The Dell UPS protects equipment from downtime, damage and data loss due to power problems.
During a power outage, the Dell UPS backup power supplies allow you to maintain power long
enough to save data and shut down equipment properly. As an added benefit, the systems also
protect against power surges and disruptive line noise.
Each Dell UPS is rated for maximum output power expressed in Watts (W), which describes the total
load that can be managed across all receptacles. All models are built to run at up to a 97% efficiency
rating.
Dell's line- interactive (LI) tower and rack- mount UPSs provides reliable, vital power backup of IT
equipment ranging from 500W to 5600W. LI models regulate voltage by boosting input utility
voltage up or moderating (bucking) it down as necessary before allowing it to pass to the protected
equipment— or resort to battery power.
Dell's online (OL) high- efficiency rack- mount UPSs offer the best combination of power protection
and reliability for backup of critical IT equipment covering 2700W to 5600W by isolating equipment
from raw utility power. These models combine power back- up and power conditioning for
continuous cleaner power and protection against all power disturbances.
The internal batteries in Dell UPSs can run protected equipment for five to ten minutes (depending
on the model) at full load during a power outage, or up to triple that time if the UPS is at half load. In
that time, system administrators can gracefully shut down connected systems or transfer to
generator power. In high reliability environments where it is important to keep systems running
rather than shut them down, an optional external battery module (EBM) can extend battery runtime
three or four times for all but the smaller (500W) Tower UPS and (1000W) Rack UPS models.
Dell UPS systems come with installed management software, an advanced graphical LCD, and tool-
less rack mounting using the Dell ReadyRails interface. The large backlit display, available in nine
languages, allows you to easily view system status and configure UPS parameters and options,
providing a comprehensive view of the UPS status and easy navigation among functions. Remote
monitoring and DMC integration are enabled with the optional network management card, which
supports secure access from anywhere over the company LAN or the Internet, with no additional
software required. With this configuration, you can manage multiple UPSs, control multiple servers
connected to a UPS, and conduct orderly, unattended power shutdown of connected equipment.
Management solutions
Dell rack solutions include Dell keyboard, video, mouse (KVM) console switches and Dell keyboard,
monitor, mouse (KMM) consoles.
Keyboard, video, mouse switches
The Dell KVM console switches enable users to need only one keyboard, mouse, and monitor to
simultaneously access multiple servers. Similar to the Dell servers and UPS, the KVM can be easily
mounted into a 1U space in the front or back of a Dell rack using a tool- less ReadyRails kit. Dell
offers both analog and remote switches, all of which are Trade Agreement Act (TAA)- compliant.
The Dell KVM 1081AD and 2161AD server console switches (SCS) provide KVM functions at the rack
for 8 or 16 devices through one or two local ports. These analog switches offer an optional remote
access key as an upgrade. The SCS easily enables control of multiple servers from a single console.
