EISK8M Series
Managed Switching Hub for Automation Systems
Installation Guide
EISK8M managed switches provide capabilities beyond both Plug and Play (PnP) and
configurable switches. Besides conventional PnP features (auto-negotiation, 10/100 Mbps
data rate, half- or full-duplex operation, flow control), the EISK8M adds advanced features
such as RapidRing™, VLAN, Trunking, Quality of Service (QoS), Port Mirroring and
the Simple Network Management Protocol (SNMP).
Each switch provides preamble regeneration with symmetry and amplitude compensation
and retimes signals to eliminate jitter. Digital pre-emphasis compensates for inherent
signal strength roll-off. Link integrity is monitored, verifying that a working adapter or hub
is on the distant end of a segment.
Configuration is done via a web browser from a computer set to communicate on the
same LAN as the switch default IP address of 192.168.92.68.
All ports support flow control using PAUSE for full-duplex links and backpressure for
half-duplex. All RJ-45 ports feature Auto-MDIX for ease of cabling.
Each switch is powered from low-voltage AC or DC sources and redundant power
connections are provided for backup considerations. The front of each unit features a
power LED, a management status LED and bi-colour LEDs for the link status, activity,
and data rate of each port.
The EISK8M features a writeable label for easy identification of the remote device
attached to each cable.
If needed, you can reset factory default settings via an aperture located on the bottom
of the unit.

Power Options
Power Considerations
Voltage in the specified range must deliver current commensurate with power
consumption. The recommended size for solid power conductors is 16–22 AWG; for
stranded conductors, use 16–18 AWG. COM is directly connected to zero volts and the
chassis is isolated from zero volts. Input connections are reverse-polarity protected.
LED Indicators
The ―PWR‖ LED glows solid green when the switch is properly powered. The
behaviour of the ―STAT‖ LED is explained in the Software Manual. To aid in
troubleshooting, each port has two LEDs. The Port 1 LED labelled ―L‖ glows solid if a
link exists, flashes to show activity and shows data rate by colour: green for 100 Mbps
and yellow for 10 Mbps. The LED labelled ―D‖ glows solid green if full-duplex is on or
is unlit when that port is operating in half-duplex mode — but in half-duplex operation it
will flash if a collision occurs. The LEDs of Ports 2–5 are unlabeled but work the same
as the Port 1 LED. The fibre port LEDs glow solid green when a link exists and flash to
show activity.
Reset Switch
If needed, you can reset factory default settings via a hole on bottom of the unit. Use a
paperclip or similar tool to press the recessed button for at least 3 seconds while the
unit is powered. Then release the button and remove power for 3 seconds. Restore
power and the unit will now use its default IP values and User ID and Password which
are both blank.

Network Connections
The switch employs Auto-MDIX technology so that either straight-through or crossover
cables can be used to connect to network interface adapters or to another hub.
