eX-1CM110-TB Managed Fast Ethernet Extender Module. 1 port 10/100Base-TX (RJ-45). 2-pin Terminal Block Interlink ( VDSL2 ) connector. Installed in the MCR200 or MCR1900 Modular Chassis System, Perle Ethernet Extender Modules enable data transmission up to 10,000 feet ( 3 KM ). Use single twisted pair ( CAT5/6/7 ), coax or any existing copper wiring previously used in alarm circuits, E1/T1 circuits, RS-232, RS-422, RS-485, CCTV and CATV applications. These Managed Modules are designed for environments where the LAN is being extended and network security is critical. By using them in conjuction with an MCR-MGT Management Module installed in the chassis, support is enabled for all authentication, authorization and accounting (AAA) security services used in corporate networks, including TACACS+, RADIUS, LDAP, Kerberos, NIS and RSA. And, to further protect ID''s and passwords from someone ''snooping'' on the network, Perle Managed Ethernet Extenders provide secure management sessions by supporting SSH, SNMPv3, Telnet and HTTPS.
