1. Approach toward Power Saving by ALAXALA Products
1.1 Overview
At present, the efforts toward power saving that have spread throughout society have been also become required
for IT equipment. Especially for networks, non-stop operating environments have become the norm, and thepower consumption of entire systems has been increasing with the rapid increase in communication traffic.
ALAXALA has been attaching importance to taking action to protect the environment and has been promoting
network energy saving since the company was established. As a result, numerous power saving functions areprovided with the AX series.
In general, power-saving measures can be roughly classified into three methods.
- Cutting wasted power: Turning off power to unused parts- Power saving by green operation: Operating only the minimum parts required and stopping the remaining
parts- Introduction of green products: Changing current products to new products which take power saving into
consideration
Cases where these methods are applied to a network are shown in Table 1.1-1
Table 1.1-1 Measures for power saving in networks

- Introduce products with a high allowable operating
temperature, raise the air conditioning temperature, andreduce the power consumption of air conditioning
equipment.

In this document, an outline of the power saving functions that achieve wasted power cutting and power saving
by green operation in the AX series are described in section 1.2, and the operation methods are described in
section 1.3. Configuration setting examples are shown in Chapter 2. Also, the results of measurements taken of
power consumption in the AX series are shown in Chapter 3.

The power saving functions supported by the AX series box-type switches are outlined in (2-1) to (2-5) below.
(2-1) Unused port power feed OFF functionality[AX3830S, AX3600S, AX2500S, AX2200S, AX1250S, and AX1240S]

This functionality can reduce power consumption by stopping the power supply to unused ports.
(Notation in manual: Port power supply OFF and port blocked)(2-2) Link-down port power saving functionality[AX3830S, AX3650S, AX2500S, AX2200S, AX1250S, and AX1240S]

This functionality reduces the power consumption of link-down ports.
An optical port is not treated as an unused port which uses the power saving functionality.
(Notation in manual: Link-down port power saving functionality)(2-3) Sleep functionality[AX3830S, AX3650S, AX2500S, AX1250S, and AX1240S]

This functionality reduces power consumption significantly by putting the Switch into a sleep state for ascheduled time range. The PWR LED blinks in green for a long time while the device is in the sleep state.
All switching functions or remote access functions stop in this case. The sleep state is canceled to start thedevice when the scheduled time range is completed.
(Notation in manual: Device sleep functionality)
AX2500S supports restoration options based on WOL packet reception detection and port link-up
detection, which can restore this Switch remotely from the sleep state.
1. Restoration option based on WOL packet reception detection[AX2500S]
The sleep state is automatically canceled to start the system when WOL packet reception is detectedon the specified port in the sleep state.
2. Restoration option based on port link-up detection[AX2500S]
The device is put into a sleep state when link-down is detected on all specified ports in thescheduled time range. The sleep state is automatically canceled to start the system when link-up is
detected on any of the specified ports.
(2-4) LED luminance setting functionality[AX3830S, AX3650S, AX2500S, AX2200S, AX1250S, and AX1240S]

Through configuration, this functionality can set the luminance of the LEDs to normal luminance,darkening, or OFF. It can also set the timing of automatic operation through configuration and can selectthe setting for changing the three-level luminance automatically.

1.3 Operation of the AX series power saving functionality
The power saving functionality of the AX series enables fixed and dynamic operation (automatic control for
execution and cancelation). Moreover, Automatic control based on scheduled settings and Automatic control
based on traffic amount are available as automatic control.
The power saving schemes to be applied vary depending on how you control the execution and cancelation of
the power saving functionality. Therefore, select a proper scheme. The examples of the corresponding powersaving schemes are shown in Table 1.3-1. The images to be applied are shown in Figure 1.3-1 to Figure 1.3-3.

Operation

Control of power saving
functionality execution andcancelation

Example of corresponding
power saving scheme

Full-time execution of the powersaving functionality

Executes a power saving functionality ina fixed way- Shut down unused ports to savepower.
- To save power, set a standby
module to the cold standby state or
set a standby device to the sleep
state (Figure 1.3-1).
- Execute a power saving
functionality other than one in theautomatic control conditions withthe automatic control set (Figure
1.3-2b).

Automatic
control of thepower saving
functionality
throughexecution andcancelation

Automatic
control basedon scheduled
settings

Controls the execution and cancelationof the power saving functionality
automatically during the specified timeof the specified date (or day of theweek)- Save power during a set time
range, such as midnight or on
holidays, in which a decrease intraffic amount is expected
beforehand (Figure 1.3-2a).
- Specify the time range for when
the power consumption is to be
reduced and reduce the peak
power of all the equipment (Figure
1.3-2b).

Automatic
control basedon traffic
amount#1

Executes a power saving functionality
automatically when traffic amountdecreases continuously; cancels it
automatically when traffic amountincreases continuously- Save power even when the time
range in which traffic decreases
cannot be determined (Figure
1.3-3).

#1 The automatic control based on traffic amount is supported only in AX6700S and AX6600S.
The full-time execution of a power saving functionality can be used in combination with Automatic control
based on scheduled settings or Automatic control based on traffic amount. During the execution of a powersaving functionality by automatic control, the power saving functionality specified for automatic control takes
priority. Automatic control based on scheduled settings and Automatic control based on traffic amount cannot be
used together.
After that, the time range in which the schedule of a power saving functionality is set is called the scheduled time
range. The time range in which no schedule is set and in which the automatic control based on traffic amount is
not performed is called a normal time range.

2. Power Saving Settings in the AX Series
2.1 Preparation for power saving settings
In setting the configuration of power saving measures, pay attention to the following:- Plan the power saving functionality used and its operation through preparation after referring to Table 1.2-1
and Table 1.2-2.
Automatic control based on scheduled settings cannot be used jointly with Automatic control based on
traffic amount.
In Automatic control based on traffic amount, the traffic amount is large at all times. Therefore, apower saving functionality may not be executed depending on the operating conditions.

- When Automatic control based on scheduled settings is used
Specify a command that states a scheduled time range and a command that specifies the operation of apower saving functionality in a scheduled time range.

- When Automatic control based on traffic amount is used
Specify a command that validates Automatic control based on traffic amount and a command thatspecifies the operation of the power saving functionality to be executed due to the decrease in traffic.

- When Automatic control based on scheduled settings or Automatic control based on traffic amount is used
Set the execution or cancelation of all power saving functionality that support the automatic control to
be used.
A power saving functionality operates based on the default setting of each command when aconfiguration setting command is omitted.
To prevent a device from not operating as expected, set all corresponding power saving functionality
explicitly when using automatic control.
The operation of each command when set to default settings is shown in Appendix A.

This measurement differs from the measurement conditions in which the rough standard of a power saving effectdescribed in Chapter 2 was obtained.
Reference achievement rate = (Reference value ÷ Measurement result) ×100 (%)
According to the Law Concerning the Rational Use of Energy (revised in 2009), this applies to a device of within
16 in the maximum supply power rate of the PoE. The Law Concerning the Rational Use of Energy (revised in2009) does not apply to the AX1240S-24P2C because the maximum supply power rate of the PoE is high (22.456).
