10.4. Battery Backup
An external USB battery can be used to maintain uptime for the manageability of the iBoot-PDU during power
outages. Using a battery, in co
njunction with a voltage alarm and email sequence provides a ‘Call-For-Help’
function that alerts personnel when there is a power failure at the facility.
To properly size the battery, the following guidance is provided
Power draw on USB-B port when the iBoot-PDU is not on battery: 7mA max. Estimate 9.5 days on a 1600mAh
battery that is not being recharged.
Power draw on USB-B port when the iBoot-PDU is on battery: 250mA max. Estimate 6.4 hours on 1600mAh
battery.
Please Note.
When the iBoot-PDU goes onto battery power, the USB-A ports will be disabled to prevent
excessive draining of the battery. Resumption of A/C power requires a manual restart of the USB ports to resume
their operation. Select the Reboot function on the iBoot-PDU to restart the USB-A ports if they are being used.
