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.
