5 Port Industrial ethernet switch 
with 4 Poe Injector Ports
EIRP305-T
The EIRP305-T is a five Port Unmanaged Industrial Ethernet Switch with 
four 802.3af (Alternative A) end-point Power-Over-Ethernet injector ports. 
As power sourcing equipment (PSE), these ports can be used to power 
802.3af compliant powered devices (PD). This eliminates the need for a 
separate power line to each end device. 
high-speed transmissions:  The EIRP305-T includes a switch controller 
that automatically senses transmission speed (10/100 Mbps). The RJ-45 
interface also auto-detects MDI or MDI-X, eliminating the requirement for 
a crossover cable. Each port is buffered and supports store-and-forward 
protocol.
dual Power input: To reduce the risk of power failure, the EIRP305-T 
provides two 48 VDC power inputs. If the power fails, the switch will 
automatically use the secondary power input.  Also, if the power goes out 
the corresponding P1 or P2 LED will go out and the Fault LED will light.  
The contacts for the alarm output will also open.
Flexible Mounting: The switch features a space saving IP30 metal 
enclosure that can be DIN or Panel mounted.
transient Protection: The power line input on the EIRP305-T offers 
protection from up to 3,000 V EFT. The Ethernet ports offer up to 6,000 V 
ESD protection. These features make the switch reliable and suitable for 
use in harsh electrical environments.
wide operating temperature: With an operating temperature of -40 
to 75°C (-40 to 167°F), this switch is suitable for use in some of the 
harshest industrial environments that exist.
easy troubleshooting: There are two LED indicators for each port that 
display the link status and transmission speed.  Three LED indicators for 
power (P1, P2 and Fault) show power status. FWD LED’s for each PoE port 
indicate if the switch is providing power to the end-point device. These 
indicators allow you to quickly diagnose and correct problems and ensure 
your network remains reliable.
