CAUTION
: The PoLRE switch supports a maximum of 2 uplink connections, either both
GbE
ports,
both
Gbic
ports, or one of each. If you want to use one
GbE
port and one
Gbic
port,
the port
numbers must be different
, for example
GbE 1 and Gbic 2
, or
GbE 2 and Gbic 1
. If you connect
through same-numbered ports, for example
GbE 1 and Gbic 1, only the fiber optic connection
(Gbic) will work
.
GbE Port Connection
To connect the PoLRE switch to the uplink network switch or IP PBX using a copper LAN cable:
•
Connect your CAT5e copper LAN cable to port
GbE 1
or
GbE 2
on the front panel of the PoLRE switch.
CAUTION
: Do not connect both ports to the network unless STP/RSTP is enabled. For more
information, see the PoLRE Switch User Guide as well as the 3300/MCD Resiliency Guidelines.
Note
: Both ports can be used. If only one connection will be installed, use the port labeled
GbE 1
.
Gbic Port Connection
CAUTION
: Do not connect a fiber optic cable to a
Gbic
port on the PoLRE switch if a legacy analog
or digital phone is still connected at any endpoint in the system. The default configuration of the
PoLRE switch provides power to all ports on boot-up, and the presence of legacy phones at the
endpoints could cause transient, low-end noise in the network.
Before you can connect a fiber optic cable to a
Gbic
port, you must install an SFP transceiver module that
matches the requirements of your environment. The PoLRE switch supports 1000 Base-
TX/SX/LX/EX/ZX/LHX, depending on which SFP transceiver module you install. The SFP modules must be
ordered from Phybridge Inc.
