NOTE:
It is recommended that high quality CAT5 cables (which work for both 10Mbps and 100Mbps) be
used whenever possible in order to provide flexibility in a mixed-speed network, since the ES
series switch ports are auto-sensing for either 10 and 100Mbps.
3.2.1 Connecting Twisted Pair (RJ45, CAT3 or CAT5, Unshielded or Shielded)
The following procedure describes how to connect a 10BASE-T or 100BASE-TX twisted pair
segment to the RJ45 port. The procedure is the same for both unshielded and shielded twisted pair
cables.
1.
Using standard twisted pair media, insert either end of the cable with a RJ45 plug into the RJ45
connector of the port. Note that, even though the connector is shielded, either unshielded or
shielded cables and wiring may be used.
2.
Connect the other end of the cable to the corresponding device.
3.
Use the LINK LED to ensure proper connectivity by noting that the LED will be illuminated when
the unit is powered and proper connection is established. If this does not help, ensure that the
cable is connected properly and that the device on the other end is powered and is not
defective.
4.
For Port #1 or 1SW, if the LINK LED is not illuminated, slide the switch, which has a crossover
or uplink for linking to another hub or switch.
3.2.2 Connecting Fiber Optic ST-type, “twist-lock”
The following procedure applies to installations using ST-type fiber connectors. This procedure
applies to ports using multi-mode ST fiber connectors.
1.
Before connecting the fiber optic cable, remove the protective dust caps from the tips of the
fiber connectors. Save these dust caps for future use.
2.
Wipe the ends of the dual connectors clean with a soft cloth or lint-free lens tissue dampened in
alcohol. Make certain the connectors are clean before connecting.
Note:
One strand of the duplex fiber optic cable is coded using color bands at regular intervals;
you must use the color-coded strand on the associated ports at each end of the fiber
optic segment
.
3.
Connect the Transmit (TX) port (light colored post) on the fiber port to the Receive (RX) port of
the remote device. Begin with the color-coded strand of the cable for this first TX-to-RX
connection.
4.
Connect the Receive (RX) port (dark colored post) to the Transmit (TX) port of the remote
device. Use the non-color coded fiber strand for this.
5.
The LINK LED on the front of the fiber connector will illuminate when a proper connection has
been established at both ends (and when power is ON in the unit). If LINK is not lit after cable
connection, the normal cause is improper cable polarity. Swap the fiber cables at the fiber
connector to remedy this situation.
3.2.3 Connecting Fiber Optic SC-type, "Snap-In"
When connecting fiber media to SC connectors, simply snap on the two square male connectors
into the SC female jacks of the fiber connector until it clicks and secures.
3.2.4 Connecting Fiber Optic MTRJ-type
When connecting fiber media to MTRJ connectors, simply snap the MTRJ plug into the MTRJ
connector of the port.
3.2.5 Power Budget Calculations for ES-FUTP-8 Fiber Media
Receiver Sensitivity and Transmitter Power are the parameters necessary to compute the power
budget. To calculate the power budget of different fiber media installations using Waters’ ES products,
the following equations should be used:
OPB (Optical Power Budget) = P
T
(min) - P
R
(min)
