Chapter 2: Battery installation and removal
Battery usage and storage conditions
■
The life expectancy of your battery should be several years, provided that it was
purchased from an approved source.
■
Your battery goes through a calibration procedure when it is first installed or replaced.
This procedure can take up to 72 hours to complete and is repeated every six months.
■
If your battery becomes fully drained during a power outage, the calibration procedure
will need to be repeated.
■
The battery should be installed in your telephony modem at all times.
■
Do not store the battery separately from your telephony modem for a prolonged period
of time.
Battery disposal guidelines
To ensure compliance with current and future rechargeable battery take-back laws, ARRIS
has joined Call2Recycle, a collection program for rechargeable batteries throughout North
America. US and Canadian customers should visit
to properly recycle
your lithium-ion battery backup units (BBUs).
Getting battery status
To assess if the battery needs to be replaced, your telephony modem charges, discharges,
and recharges the battery pack as part of a battery test. Your telephony modem re-tests
the battery periodically, usually every 180 days. The battery LED and the Registration Status
screen indicate the status of the battery. Your telephony modem will transmit a two-second
stutter tone when the battery level is low.
To view the Registration Status screen:
1. Using a web browser, access
192.168.100.1
.
You may have to manually adjust your computer's IP address, for example,
192.168.100.6 to access the HSD pages.
2. Click the
CM State
link below the ARRIS banner.
3. Scroll down to see the Power Supply Telemetry and Battery Test State information at the
