13.3.7 Connectors
Table 13-12 summarizes all of the connectors on the ShoreGear voice switches. Diagrams
showing where these connectors are located are provided later in this chapter. Power Cabling
Each ShoreGear voice switch comes equipped with a standard 110 VAC modular power
cord. A localized modular power cord can be ordered from ShoreTel. ShoreTel recommends
that every ShoreGear voice switch, as well as the ShoreWare server, be connected to an
uninterruptable power supply (UPS). Ethernet Cabling
Each ShoreGear voice switch has two RJ-45 connectors that provide an auto-sensing 10/
100M Ethernet interface. These are connected to the local area network using standard
Category 5 cabling.
ShoreGear voice switches come with two network interfaces, LAN1 and LAN2, allowing for
a network fault tolerant deployment. You can connect to either or both connectors; there is
no primary/secondary relationship. When both are connected, only one will be active at
any time. If the currently active interface loses the link, the alternate interface becomes
active. Both interfaces will use the same MAC Ethernet address, and IP address.
There are two levels of fault tolerance. To protect against Ethernet switch failure, connect
LAN1 and LAN 2 to separate Ethernet switches. To protect against port or cable failure,
connect LAN1 and LAN2 to separate ports on the same Ethernet switch.
10 Base-T and 100 Base-T can typically support up to 100 meters.
