3-28 SHUB8 Installation
Chapter 3 - Installation
LEDs
The SHUB8 has a Power LED and LAN connector LEDs. Each LAN connector has a green
LED indicating Link and activity and a yellow LED indicating Link speed (ON for 100Mbs,
OFF for 10Mbs).
Remote Power Switch
Each switch port of the SHUB8, except the "UPLINK" port can provide a 48VDC feed over
the LAN employing pin pairs 4 & 5 (+) and 7 & 8 (-) of the RJ-45 connector. Power feed is
controlled by the eight-position DTE POWER FEED dip switch; in the ON position power is
supplied. These switches should be placed in the OFF position until all system wiring is
complete. Once complete, the individual ports serving an IP Keyset can be turned ON
using the corresponding switch position (1-8), refer to
Figure 3-20.
Wiring Connectors
Before wiring any of the Modules, first connect the screw on the back of the Module to a
known earth ground, refer to
“Module Grounding” on page 3-14.
On the front of the SHUB8 are the "UPLINK" and eight switched "1X-8X" connectors, each
an RJ 45 type. These connectors should be wired to the appropriate LAN points as
discussed in
“LAN Connections” on page 3-15 and “LAN Wiring Structures” on page 3-16. If
cascading is necessary, refer to
“LAN Wiring Structures” on page 3-16.
 Wire the "UPLINK" port to the corporate LAN router or switch. A SHUB8 can be
used to form the
Telenium
IP
Zone.
 Wire each "X" port to an RJ-45 wall/floor jack at an IP Keyset or VoIP terminal
location, or to the "LAN" port of another IP KTS Module.
 Tag or number wiring for maintenance.
AC/DC Adapter
Assure the AC/DC Adapter is plugged into a live AC outlet and the Module Power jack.
Caution: The power feed provided by the SHUB8 will cause damage to other LAN
devices. Prior to switching any of the dip switch positions ON, assure that only an IP
keyset or a DSS console is connected to the SHUB8 switched LAN port.
