Model EIP308 
8-Port 10/100 
Ethernet Switch 
 
 
Description 
ModeI EIP308 is an 8-port 10/100 switch designed for the not-so-friendly industrial environment. The unit is housed in a 
rugged metal enclosure ready to be mounted on a DIN rail or panel. The switch is an unmanaged Layer 2 switch that 
provides auto MDI/MDIX crossover for easy plug-and-play applications. 
 
LEDs indicate power, speed and link/activity for easy visual diagnostics. External power supply is connected to three 2-
position pluggable terminal blocks. A 9-30 VDC is the main power supply input. It also has a redundant 9-30 VDC for 
secondary DC source. If that is not enough, 24 VAC yields the third option for power supply. B&B Electronics’ power supply 
model 12DC1AST (9-30 VDC @ 1000mA) is required, not included.

Applications
 
 
 Building automation 
 
 
 Process control 
 Ethernet I/O 
 
 
 
 Motion control 
 Remote data acquisition   
 
 Environmental control 
 Communications gateway

Connections 
Standard RJ45 female connectors are provided. Standard RJ45 plug cables are all that is necessary to connect your 
devices since the switch supports auto crossover. External power supply is connected using one of the three 2-position 
pluggable terminal blocks for convenience. Table 1 shows the RJ45 pinouts and Table 2 shows the LED indicators.
