Alarm input (DI) |
The system detects exceptions of the connected device based on the input voltage changes on the alarm input connection. · State: ¡ 1: +13 to +30 V ¡ 0: –30 to + 3 V · Max. input current: 8 mA |
|||
|
Alarm output (DO) |
Uses a relay for output, with a current carrying capacity of 1 A @ 24 VDC. The relay outputs alarms by opening or closing the contact. |

Enables or disables link aggregation on XGE 1/0/25 and XGE 1/0/26 |
Enables or disables RRPP on XGE 1/0/29 and XGE 1/0/30 |
When DIP switch 1 is on, flow control is enabled on all ports. When DIP switch 1 is off, the status of the flow control feature depends on the configuration. For more information about flow control, see Ethernet interface configuration in the configuration guides for the switch.
When DIP switch 2 is on, broadcast suppression is enabled on all ports. When DIP switch 2 is off, the status of the broadcast suppression feature depends on the configuration. For more information about broadcast suppression, see Ethernet interface configuration in the configuration guides for the switch.
When DIP switch 3 is on, the system creates Layer 2 aggregation group 1 and adds the two uplink Ethernet ports to the group. When DIP switch 3 is off, the status of the link aggregation feature depends on the configuration. For more information about Layer 2 link aggregation, see Ethernet link aggregation configuration in the configuration guides for the switch.
When DIP switch 4 is on, RRPP is enabled. When DIP switch 4 is off, the status of the RRPP feature depends on the configuration. For more information, see RRPP configuration in the configuration guides for the switch.

LSWM2EC |
|
|
Description |
The LSWM2EC EPS scanner module scans network-wide endpoints as instructed by the EPS server for port type and operating system type automatically and sends scanning results to the EPS server. Upon receiving the port information, the EPS server provides a baseline management over the endpoints that access the network system. By using this module on a switch, you can save hardware resources, increase the number of endpoints that can be scanned, and perform incremental scanning. |
