Can I running 9V router on 12V?
However, the 9 Volt router cannot be run on the 12 Volt UPS. The 9 Volt router is meant to be run on 9 Volts and attempting to power it with the 12 Volt UPS will result in an overvoltage thus permanently damaging the router. No, it will not be possible to do that.
Can I use a 12V 1.5 A power adapter on 12V 2a device?
Yes, there will be no problem. As long as the voltage of 12 Volts is same, it will work perfectly fine on a 12 Volt 1 Amp power supply as it would on a 12 Volt 0.17 Amp power supply.
Can I use a 9 volt adapter on a 12 volt device?
It depends on whether your power supply is regulated. If you need regulated (stable) 12V, and the 9V supply is unregulated, it could give you up to 14V or slightly higher when not loaded.
Can you use a 12V 1.5 a charger on a 12V 2A device?
Yes, you can use a 12V 3A power adapter on 12V 1.5A device. You can also use a 12V 0.5A power adapter but the charging time will be three times longer. If you are a cautious person then you should use a manufacturer recommended power adapter.
Can I use a 12V 1.5 A power adapter on 12V 2A device?
Is it OK to use higher voltage adapter?
Higher current (A) is okay because the device won’t use as much, but higher voltage (V) is going to “fry” it. Conversely, lower voltage is unlikely to cause damage since the device simply won’t have enough power, but lower current can cause trouble because the power supply cannot provide enough.
What happens if you use a higher voltage charger?
By using different voltages, you risk shortening the lifespan of your batteries and your device. Amperage is the power pulled by your device while being charged and used. So your device chooses how much amperage is needed based on what you’re doing.
How do I connect my Cisco 819 ISR to an AC power outlet?
To connect your Cisco 819 ISR to an AC power outlet, follow these steps: Step 1 Connect the AC adapter to an AC power outlet. Step 2 Plug the adapter cord into the router. Warning This product relies on the building’s installation for short-circuit (overcurrent) protection.
Can I order my own Ethernet cable from Cisco?
If you must supply your own cable, see the “Cisco 860, 880, 890 Series” section for cabling specifications. If this appendix does not provide specifications for a particular cable, we strongly recommend ordering the cable from Cisco. To connect a PC (or other Ethernet devices) to an Ethernet switch port, follow these steps:
Why is my WLAN only 12 Mbps in the microwave area?
So, if your access point was designed to achieve 24 Mbps, it may now be reduced to 12 Mbps in the vicinity of the microwave when it operates. If your only application on the WLAN is convenience data networking (for example, Web surfing), this loss of throughput may not be immediately obvious.
How do I connect an Ethernet switch to a Cisco router?
To connect an external Ethernet switch to an Ethernet switch port on the router, perform these steps: Step 1 Connect one end of the yellow Ethernet cable to an Ethernet switch port on the router. Figure 3-2 shows a Cisco 888W router connected to an Ethernet switch.
