4.5 LED’s
PWR:
Illuminates GREEN, steady on when power applied.
ERROR:
Indicates the self-test at power up was not successful
SPEED:
Per port, ON = 100Mbps; OFF = 10 Mbps (when LINK is made)
LINK/ACT:
Per port, steady ON for LINK with no traffic, blinking indicates port is
transmitting and receiving.
F/H:
ON = Full-Duplex and Link, OFF = Half-Duplex and/or no Link.

Uplink Port #1 or 1SW
The switches have one manual crossover (MDIX uplink) switch, port 1SW, located on the
front. This port can operate either full/half duplex mode.
The uplink (or crossover) on the #1 or 1SW port allows its RJ45 cable to connect for cascading
to another hub or switch port. This allows repeater-to-repeater connections without a special crossover
cable. Port #1 works the same as regular ports for 10Mbps or 100Mbps speed auto-sensing
connections.
Cascaded connections may be operated at either 10 or 100Mbps. The ES-FUTP-8 even
supports cascaded connections of both 10Mbps and 100Mbps at the same time on different ports.
When attaching a 10Mbps hub or switch, the Ethernet configuration rules (hop count limits, etc.) for
10Mbps domains are in effect. When the cascaded connection is operated at 100Mbps speed,
because of its full duplex and switched port capability does not need any PDV calculation for
distances. Two ES switches cascaded using RJ45 ports will auto-negotiate to operate the connection
at 100Mbps.
4.7
Use with Media Converters
Where an additional fiber connection (beyond the built-in fiber port as in the ES-FUTP-8
model) may be desired, a media converter may be used. For the ES-FUTP-8, the first two switched
ports can be set to FDX manually, making typical 100Mbps media converters (which can be
troublesome with auto-negotiating ports, defaulting to 100Mbps half-duplex) usable in either HDX or
FDX mode as set by the user.
For the ES-CUTP-8, the switched port #2 at “F” position supports only 100Mbps fixed full
duplex.
5.0 TROUBLESHOOTING
All Waters Network Systems’ Ethernet switching products are designed to provide reliability
and consistently high performance in all network environments. The installation of ES-FUTP or ES-
CUTP switches is a simple procedure (see Section 3.0, INSTALLATION); operation is easy and is
described in Section 4.0, OPERATION.
Should problems develop during installation or operation, this section should help to locate,
identify and correct such problems. Please follow the suggestions listed below prior to contacting
your supplier. However, if you are unsure of any procedure described in this section, or if the
switches are not operating as expected, do not attempt to repair or alter the unit. Contact your
supplier or Waters’ Customer Service at
800-328-2275
or
for assistance.
5.1
Before Calling for Assistance
1.
If difficulty is encountered when installing or operating the switch refer back to Section 3.0,
Installation and Section 4.0, Operation. Check to make sure that the various other components
of the network are operable.
2.
Check the cables and connectors to ensure that they have been properly
connected and
the cables/wires have not been crimped or in some way impaired during installation. (About
90% of network downtime can be attributed to wiring and connector problems.)
3.
Be certain that the AC power cord is plugged into a functioning electrical outlet. Make sure that
the AC power cord is properly plugged into the switch. Use the PWR LED to verify the unit is
receiving proper power.
