Product Description - General
Waters’ ES family of enclosed switches provides the switching speed and reliability to smoothly
support multiple workgroups at 10Mbps or 100Mbps speed. The optional fiber port is configured and
tested in the factory and is available in all popular fiber connectors.
The ES-FUTP “Future-proof Fiber” models have been designed with one full-duplex 100Mbps
switched fiber port, and seven “N-way” switched RJ45 with full/half-duplex 10/100 auto-negotiating RJ45
ports. The ES-CUTP “Copper” model has been designed with all eight RJ45 switched ports with “N-way”
x half/full duplex capability and functions as 10/100 auto-negotiating ports.
Designed for use in labs, classrooms and in network traffic centers, the ES switches are easy to
install and use. Addresses of attached nodes are automatically learned and maintained, adapting the
switching services to network changes and expansions. Top-mounted LEDs provide status information
on each port. The ES switches provide high performance plug-and-play operation in compact packages.
The ES switches are non-blocking on all ports and include 1MB packet buffers and 16K-node
address table for advanced performance. With store-and-forward switching, the switches filter all faulty
packets to minimize traffic congestion.
2.2.1 ES-FUTP
Switch
The ES-FUTP-8 chassis houses one main PC board. The power supply unit is external. The
front side of the chassis has eight RJ45 twisted-pair ports and one 100Mbps fiber port. Port # 2SW
supports the fiber port only and the RJ45 connector is inoperative at all times. LEDs to indicate
operating status of all ports are mounted on the top. There are power (PWR) and ERROR (self-test at
power up failed) indicators for the unit. For each port, there are Link and Activity (LINK/ACT) LEDs
indicating traffic, and speed (ON for 100Mbps), and full/half (F/H) duplex indicators.
The DC power plug connector or “jack” is in the left rear of the chassis. The external power
supply is 5VDC at 95 - 125vac at 60 Hz.
2.2.2 ES-CUTP-8 with all RJ45 copper ports
The ES-CUTP-8 houses one main PC board and the power supply unit is external. The front
side of the switch has eight twisted-pair switched ports. Port 2SW has manually selectable full-fixed and
auto-negotiation capability. See section 4.4.

full duplex) indicators.
The DC power plug connector or “jack” is in the left rear of the chassis, like the ES-FUTP-8. The
external 5VDC power supply is for 95 - 125vac at 60 Hz.
2.3
Uplink Port 1SW for Cascading
The unit has an uplink Port #1 or 1SW, located on the left-front side of the switch. It enables the
port’s twisted pair cable to cascade to another shared hub or switch. (See Section 4.6 for more details
about uplink). Port #1SW is capable of full- and half-duplex mode auto-sensing, based on the capability
of the connected device. The uplink feature operates the same, whether Port # 1SW is connected to
either 100Mbps or 10Mbps devices. When the uplink port is used to cascade two ES switches, the auto-
sensing feature will cause the connecting link to operate at 100Mbps speed and full-duplex mode.
