Power supply time of batteries on the S5700-BAT

0

Power supply time (in hours) of batteries on the S5700-LI-BAT:
S5700-28P-LI-BAT
- When the BAT-4AHA battery is used, the power supply time is 2.4 hours if the switch works with the maximum power consumption; the power supply time is 4.1 hours if the switch works in a typical scenario; the power supply time is 5.6 hours if the switch works with the minimum power consumption.
- When the BAT-8AHA battery is used, the power supply time is 4.8 hours if the switch works with the maximum power consumption; the power supply time is 8.2 hours if the switch works in a typical scenario; the power supply time is 11.2 hours if the switch works with the minimum power consumption.
S5700-28P-LI-24S-BAT
- When the BAT-4AHA battery is used, the power supply time is 1.2 hours if the switch works with the maximum power consumption; the power supply time is 2.1 hours if the switch works in a typical scenario; the power supply time is 4.1 hours if the switch works with the minimum power consumption.
- When the BAT-8AHA battery is used, the power supply time is 2.3 hours if the switch works with the maximum power consumption; the power supply time is 4.2 hours if the switch works in a typical scenario; the power supply time is 8.3 hours if the switch works with the minimum power consumption.
Notes:
- In a typical scenario, 70% of interfaces are in Up state, each interface transmits 10% of maximum traffic, and the EEE function is enabled.
- The power supply time shortens when a battery has been used for a long time.

S5700-BAT's support for batteries
S5700-BAT's support for batteries is as follows: An S5700-LI-BAT series switch has a built-in AC power supply unit and can use a pluggable power module or battery for power redundancy. 1. If a battery is configured, the battery can automatically supply power to the switch in cased of a mains power outage, ensuring uninterrupted services. When the AC power supply recovers, the battery automatically turns to the charging state. The S5700-LI-BAT switch supports the following batteries and battery charger module: - BAT-4AHA (chargeable lithium battery) - BAT-8AHA (chargeable lithium battery) - PBB-12AHA (12 AH lead-acid battery charger module connected to an external lead-acid battery with 12 AH of rated capacity) 2. If a power module is configured, the power module can function as a backup of the built-in power supply unit to improve power reliability. The S5700-LI-BAT switch supports the following power modules: - 150 W AC power module - 150 W DC power module To query a switch's support for batteries, see Hardware Query Tool.

How to view the serial number of an S series switch
Serial numbers of S series switches fall into two categories: - Equipment serial number (ESN): indicates the serial number of a switch. The ESN of a modular switch is also called the chassis serial number. - Serial number (SN) of each component: indicates the serial number of a card, subcard, optical module, power supply, or fan module. Select one of the following methods to obtain the ESN or SN of a switch or component: Method 1: View SN labels. Equipment or chassis SN: View the SN label attached to the device panel. (There is a slight difference between label locations on different models. For example, the label can locate on the front, rear, or top of the chassis.) Card serial number: View the SN label on the panel (upper-right or upper-left corner) or PCB (remove and check the card). Method 2: Run a command. Run the display elabel command to view the electronic label of each component. The BarCode field indicates the serial number. Method 3: Through the web system. When the web system is enabled on a device, view the chassis serial number through the web system. EasyOperation web system (supported only in V200R005 and later versions) Log in to a device through the web system and click Monitor on the toolbar to enter the Monitor page. You can view device information, including the chassis serial number. Web system classical version Log in to a device through the web system and click Device Summary on the toolbar to view device information, including the chassis serial number.

How to configure PoE power-on and power-off management on S series switches
A switch supports automatic and manual power-on and power-off modes. Run the poe power-management { auto | manual } slot slot-id command (the slot slot-id parameter is optional for fixed switches) to configure the PoE power management mode. The auto parameter indicates the automatic power management mode, and the manual parameter indicates the manual power management mode. By default, a switch uses the automatic power management mode. You cannot configure the power management mode on the PoE switch S5720-16X-PWH-LI-AC.

In automatic mode, run the poe priority { critical | high | low } command in the interface view to set the power supply priority of a PoE interface. The priorities in descending order are critical, high, and low. By default, the power supply priority of an interface is low. When the available power is insufficient, the device provides power first for the PDs connected to interfaces with higher power supply priorities. In manual mode, run the poe { power-off | power-on } interface interface-type interface-number command in the system view to manually power on or power off the PD connected to an interface. The power-off parameter indicates that the PD connected to an interface is powered off, and the power-on parameter indicates that the PD connected to an interface is powered on.
