5. Installation
(1) Operating Environment
ER-5390P must be installed and operated within the limits of
specified operating temperature and humidity (see previous section
under Specifications). Do not place objects on top of the unit. Do
not obstruct any vents at the sides of the unit. Do not position the
hub near any heating source such as heater, radiator, or direct
exposure to sun. Prevent entering of water and moisture into the unit.
If necessary, use dehumidifier to reduce humidity.
(2) Connecting network devices
Connect one end of the network cable to any of the RJ-45 or
BNC connectors on the rear panel, and connect the other end of the
network cable to the network device with RJ-45 or BNC connector
and the maximum length between the hub and any network devices
UTP is 100 meters (300ft) and BNC is 200 meters (650ft). Once the
network cable is connected on both ends and the attached network
devices are powered on, the Link Status LED should be lit.
(3) Uplink to Another Hub
The Uplink function is designed to extend your segment by
connecting to another hub. Note that the Ethernet Hub’s port 1 can
be switched to an uplink function by switching the sliding switch.
There are two ways for you to connect to another hub:
1) Switch the sliding switch to the uplink mode to convert port 1 to
an uplink and use a straight-through twisted-pair cable to
connect port 1 to another hub.
2)
If you use a crossover cable to connect the two Hubs, then you
can use any port on the Ethernet Hub to connect to any normal
port on the other Hub. Please note: the uplink port must be in
normal mode for the method to work.
