Power failure
Due to frequent power failures,
PCs are hardly used, and user
terminals with backup power
supplies or batteries are commonly
used, such as laptops, tablet PCs,
and smart phones.
Power failures for minutes to
hours are frequent in areas
including India, Africa, and the
Middle East.

Core and aggregation layers: UPSs are
deployed as backup power supplies for
switches and servers in equipment rooms to
allow the devices to work upon a mains power
failure.
Access layer: A large number of access
devices are widely deployed on each floor of
buildings. High-quality UPSs as backup power
supplies cost high and occupy much space,
while low-cost UPSs or external lead-acid
batteries have low reliability and security,
occupy much space, and have a short service
life.

Huawei Solution to Frequent Power
Failures at the Access Layer
Huawei S5700-LI-BAT series battery LAN
switches (S5700-LI-BAT for short) are the
industry's first switch series to support built-in
batteries. If the mains power fails, batteries are
automatically used to provide power, ensuring
uninterrupted services. After the mains power
is recovered, the mains are used to provide
power and charge the lithium batteries. In this
manner, devices at the access layer are
provided with power when the mains power
fails at the access layer.

Industry's first internal battery design: The
highly integrated battery slot saves space and
facilitates battery installation.
Intelligent power management, prolonging the
standby time: Intelligent power management and
energy-saving technologies are adopted to prolong
the standby time to 11 hours.
Visualized management on battery status and
predictable battery service life: Battery status
can be displayed and managed on a web page.
The standby time alarm function allows you to
replace a battery before the battery service life
ends. You do not need to replace all batteries on
the entire network. Built-in batteries save the cost
by higher than 50% compared with the cost using
external UPS.
High battery reliability: Battery LAN switches
support various battery protection technologies and
the alarm function.

Uses external storage batteries or UPSs that occupy much
space, require power cables, and have low reliability.
Requires power cables, making the installation and

Status of the battery and switch can be
displayed on a web page, simplifying
management.
 The parameters status, capacity, and
type of the battery are displayed.
 Batteries on the entire network can
be managed in a unified manner,
and the battery service life is
predictable. When the standby time of
a battery is shorter than the threshold,
an alarm is generated, allowing you to
replace the battery before the battery
service life ends. You do not need to
replace all batteries on the entire
network. Built-in batteries save the
cost by higher than 50% compared
with the UPS solution.

High Battery Reliability
Battery Protection and Alarm
Multiple battery protection
functions such as overtemperature
protection are supported to protect
batteries. When the ambient
environment of a battery does not
meet the requirement, proper
measures are taken to protect the
battery, ensuring secure running of
the battery and preventing
damages to the battery.
 Six alarms such as the internal
battery fault alarm are supported
so that battery faults are reported
in a timely manner, simplifying
battery O&M and replacement.
