Function

Description

Power redundancy

The BAT-4AHA battery can be installed in the battery slot at the rear of an S5700-LI-BAT switch to provide power redundancy. When the external power supply system fails, the battery powers the switch to ensure uninterrupted services.

Protection

The BAT-4AHA battery provides various protection functions, including charge overvoltage protection, charge overcurrent protection, discharge overcurrent protection, undervoltage protection, and short-circuit protection.

Alarm reporting The BAT-4AHA battery can report alarms on low-power state, low/high temperature, battery failures, and power supply time.
Command line configuration You can configure the power supply time alarm threshold for the BAT-4AHA battery and turn off the battery using commands.

Overtemperature protection

The battery enters the overtemperature protection state when the charge temperature is out of the range of -5°C to +55°C or when the discharge temperature is out of the range of -10°C to +65°C. The battery restores to the operation state when the charge temperature restores to the range of 0°C to 50°C or the discharge temperature restores to the range of -5°C to +60°C.

Visualized management

You can use the web-based management system to check the battery status and manage the battery.

In-service software upgrade In V200R005C00 to V200R010C00 versions, the lithium battery software can be upgraded using the upgrade battery-app command.
Hot swapping The battery is hot swappable.

4: Battery switch button

NOTE:
  • The switch button is invalid when the battery is not installed in the switch.
  • If the switch is powered by an AC power supply system, you do not need to turn on the lithium battery by holding down this button after installing the battery in the switch. The lithium battery works in backup mode automatically after it is installed.
  • If the switch is not connected to an AC power supply system, install the lithium battery, and then hold down this button for 1s to turn on the battery so that the battery starts to power the switch.
  • You can hold down this button for 1s to turn off the lithium battery only when the switch has no AC power input.

Table 6-3 describes the indicator on the BAT-4AHA battery panel.
