Expansion modules
Table3-4 Expansion module description
|
Expansion module model |
Introduction |
Description |
|
LSWM2EC |
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. |
For more information about the module, see H3C LSWM2EC EPS Scanner Module User Manual. |
|
LSWM2-iMC |
The LSWM2-iMC intelligent network management module provides terminal admission network management for small and medium-sized campus networks. The module aims to provide network management solutions that integrate the terminal users, resources, and network services for network administrators. |
For more information about the module, see H3C LSWM2-iMC Intelligent Network Management Module User Manual. |
|
LSWM2FPGAB |
The LSWM2FPGAB NetStream interface module offers unidirectional NetStream and session-based bidirectional NetStream. After the device copies traffic to the LSWM2FPGAB NetStream interface module, the field programmable gate array (FPGA) chip in the module collects and analyzes traffic statistics and creates NetStream entries. This NetStream approach saves ACL resources, improves NetStream entry creation performance, and greatly reduces NetStream impact on the device forwarding performance. |
For more information about the module specifications, see H3C LSWM2FPGAB NetStream Interface Module User Manual. |
|
LSPM6FWD |
The module is a fourth-generation high performance firewall module. It provides features including firewall, VPN, content filtering, content identification, URL filtering, and NAT. By using this module on a switch, you can enhance the switch security capabilities without changing the network topology. |
For more information about the module specifications, see H3C LSPM6FWD Card Manual. |
|
|
NOTE: The LSWM2FPGAB interface module adds 55 mm (2.17 in) to the chassis depth. An interface module of other models (including its handle) adds 75 mm (2.95 in) to the chassis depth. |
4 Ports and LEDs
As a best practice, use H3C transceiver modules and cables for the switch. H3C transceiver modules and cables are subject to change over time. For the most up-to-date list of H3C transceiver modules and cables, contact H3C Support or marketing staff. For information about the specifications and views of H3C transceiver modules and cables, see H3C Transceiver Modules User Guide.
