When we specs in power injector for Cisco Meraki’s access point, we might come across 2 types of power Injector, what the different between MA-INJ-4-UK vs MA-INJ-5-UK? If you remember my earlier post “AIR-PWRINJ5= vs AIR-PWRINJ6=“, this one has not much different from power rating, both support maximum power output of 30 watts, yet MA-INJ-4-UK have input current 0.8A and MA-INJ-5-UK have input current of 1.5A.
Note that this also applicable toward MA-INJ-4-US vs MA-INJ-5-US (US’s power plug), MA-INJ-4-EU vs MA-INJ-5-EU (EU’s power plug), MA-INJ-4-AU vs MA-INJ-5-AU (AU’s power plug).
Differences Between Cisco Meraki Power Injector MA-INJ-4-UK vs MA-INJ-5-UK
In fact, MA-INJ-4-UK is for Cisco Meraki Access Point (AP) which requires a maximum 30 watt power output, but not using multi gigabit’s (Mgig) switch. From MA-INJ-4-UK datasheet, we can see MA-INJ-4-UK shows it compatible with Ethernet 10/100/1000 Mbit/s, full duplex.
While MA-INJ-5-UK is use for Cisco Meraki AP which also require a maximum of 30 watt power output, but utilize the Mgig feature, mean the AP is connecting to a multi-gigabit’s switch, From MA-INJ-5-UK datasheet, we can see MA-INJ-4-UK shows it compatible with Ethernet 10/100/1000 Mbps & 10 Gbps Multigigabit Ethernet.
Conclusion: The differences between MA-INJ-4-UK vs MA-INJ-5-UK is when Cisco Meraki AP that connect with Mgig’s switch, we recommend use MA-INJ-5-UK, if normal switch (10/100/1000), we can use MA-INJ-4-UK.
