Overview
Standard Features
The NETSW-EIS6-xM series switches are industrial grade sixport, 10/100 Mbps auto-negotiating switching hubs. Each switch
provides four 10/100 Mbps shielded RJ-45 connectors for twisted
pair (Ethernet) connections and two 100 Mbps fiber ports. The
NETSW-EIS6-MM supports multi mode fiber and uses ST connectors
while the NETSW-EIS6-SM supports single mode fiber and uses SC
connectors.
• 10BASE-T/100BASE-TX/100BASE-FX
Both switches operate on a nominal 24 VDC that can be supplied
from a fire alarm control panel or booster power supply insuring
power is always available. Connections are provided for redundant
power supplies.
• Broadcast storm control
The units feature broadcast storm protection and loop detection
of the network wiring. LED indicators are provided for data rate,
activity/link integrity, power and loop detection. The units can be
mounted with the NETCOM-BRKT mounting bracket in an MFC-A
enclosure.
• 24VDC Operation w/Redundant connections
• Loop detection algorithm
• Industrial Grade
• IEEE 802.3 compliant
• Auto-negotiated data rate and flow control on twisted-pair ports
• Full or half duplex
• Diagnostic LEDs
• UL-508 listed, CE mark

Application
NETSW-EIS6-xM series switches interconnect over a 100BASE-FX
style fiber optic backbone. The use of a fiber backbone makes
these switches ideal for proprietary network applications involving long networking distances. Up 9 miles (15 Km) is supported by
the NETSW‑EIS6‑SM. The fiber backbone also provides immunity to
EMI/RFI and moisture.
The use of network switch technology over a conventional hub
results in improved communications speed and network reliability.
Fire Alarm Monitoring
Considerable thought and care must be used when combining life
safety equipment and LAN technology. Systems that utilize LAN
network technology for information and reporting purposes ONLY
do not face the same network and agency listing restrictions as
systems that use the LAN to transmit control information between
the fire alarm panel and the FireWorks workstation(s). This technology is listed for monitoring applications only. All life safety applications using LAN technology should be fully reviewed with the
Authority Having Jurisdiction.
Technical Details
NETSW-EIS-xM switches segment the Ethernet network into separate collision domains. The switch functions as a “bridge” between
various data links creating a larger network than is achievable using
repeating hubs. Each twisted-pair port automatically negotiates
with its attached device the data rate for that port, either 10 or 100
Mbps. Flow control is also negotiated. Full duplex segments utilize
the IEEE 802.3x PAUSE scheme. Half-duplex segments use the back
pressure approach.
Installation and Mounting
The NETSW-EIS6-MM and NETSW-EIS6-SM are installed in a NETCOM-BRKT, which fits into the cabinet options shown below.
Switches learn the port locations of connected Ethernet devices
by reading complete Ethernet frames and observing the source
addresses. This information is then maintained as a table of source
addresses and corresponding port assignments. After address and
port information is stored, switch traffic is restricted only to those
ports involved in a transmission. This process improves switch
throughput as simultaneous transmissions can now be initiated on
inactive ports. The address and port information is automatically
“aged” facilitating changes in field wiring.
If broadcast, multicast, or unicast transmission to an unknown
destination is received on a switch port, all other ports are flooded
with the transmission. To reduce data latency, cut-through operation may be selected as opposed to store-and-forward operation.
With cut-through operation, frames are forwarded after the first
512 bytes are received. Store-and-forward operation requires a
complete frame be received before forwarding occurs.
