GS716Tv3, GS724Tv4, and GS748Tv5 Smart Switches Green Ethernet Detail Use this screen to view detailed per-port Green Ethernet information and to enable or disable Green Ethernet settings on a single port. Using the Green Ethernet features allows for power consumption savings.  To configure Green Ethernet mode settings for a port: 1. Click System > Management > Green Ethernet > Green Ethernet Detail. 2. From the Interface list, select the interface to configure. 3. Enable or disable the Green Ethernet features for the port: • Auto Power Down Mode: When this mode is enabled and a port link is down, the PHY will automatically go down for short period of time, and then wake up to check link pulses. This will allow performing auto-negotiation and saving power consumption when no link partner is present. • EEE Mode: When this mode is enabled and the send and receive sides of a link are lightly loaded, the port can transition to low-power mode. The EEE and the Short Cable modes are not supposed to be active simultaneously. 4. Click the Apply button. The Local Device Information table displays information about the Green Ethernet status and statistics on the port. Table 9. Green Ethernet local device information Field Description Cumulative Energy Saved on this port due The energy savings per port, per hour. to Green Mode(s) (Watts * Hours) Operational Status The Green Mode Energy Detect operational status, either Inactive or Active. Reason The reason the Green Mode Energy Detect operational status is active or inactive. Rx Low Power Idle Event Count The number of times the local interface has entered a low-power idle state. Rx Low Power Idle Duration (uSec) The amount of time (in 10 microsecond increments) the local interface has spent in a low-power idle state. Tx Low Power Idle Event Count The number of times the link partner has entered a low-power idle state. Tx Low Power Idle Duration (uSec) The amount of time (in 10 microsecond increments) the link partner has spent in a low-power idle state. Tw_sys_tx (uSec) The value of Tw_sys that the local system can support. This value is updated by the EEE DLL Transmitter state diagram. Tw_sys_tx Echo (uSec) The remote system's transmit Tw_sys that was used by the local system to compute the Tw_sys that it wants to request from the remote system. Configure System Information 51

Green Ethernet Detail
Use this screen to view detailed per-port Green Ethernet information and to enable or disable
Green Ethernet settings on a single port. Using the Green Ethernet features allows for power
consumption savings.
To configure Green Ethernet mode settings for a port:
1.
Click

Enable or disable the Green Ethernet features for the port:
Auto Power Down Mode
: When this mode is enabled and a port link is down, the
PHY will automatically go down for short period of time, and then wake up to check
link pulses. This will allow performing auto-negotiation and saving power consumption
when no link partner is present.
EEE Mode
: When this mode is enabled and the send and receive sides of a link are
lightly loaded, the port can transition to low-power mode. The EEE and the Short
Cable modes are not supposed to be active simultaneously.

low-power idle state.
Rx Low Power Idle Duration (uSec)
The amount of time (in 10 microsecond increments) the
local interface has spent in a low-power idle state.
Tx Low Power Idle Event Count
The number of times the link partner has entered a
low-power idle state.
Tx Low Power Idle Duration (uSec)
The amount of time (in 10 microsecond increments) the
link partner has spent in a low-power idle state.

The value of Tw_sys that the local system can support.
This value is updated by the EEE DLL Transmitter state
diagram.
Tw_sys_tx Echo (uSec)
