IPCampower Switch Issue Question

[botics]

Yikes. I got the 2960 Cisco today. I feel ovwrwhelmed. I'm so rusty with the Cisco crap. I might talk to the Ebay guy and see if he sell me like a friendlier Gui or something. I booted it up, but I didn't have much time to screw around with it, but it just sat there with a green light on in the hand, three network cables plugged into it and never got any link activity action happening so I think it needs a reset.

Reset is the story of my life…. RESET

Trying a POST 10 minutes before work is not a good idea....
Ok i found some foreigner on youtube who showed a Power up with the MODE button pressed to reset. I takes awhile for this thing to POST. So that was all it was.
I brought the little netgear inside to go with my spare router for bench testing and general tinkering.

here is an interesting find. Cisco C1000 series. These require no licensing. one reviewer joked Cisco " Affordable and License free" in one sentence? I gotta check it out.

What model number is that?

How loud is that thing? Any idea of power consumption? Cisco's datasheet here seems to suggest it uses 70 watts at 5% throughput, although to be fair that is probably with all ports populated and pushing multiple gigabits per second of data, which you won't normally be doing. But I know for some enterprise gear, efficiency features aren't a priority (like shutting off ports that aren't in use).

I am using ipcampower switches past gen 10/100/1000 mbps PoE+ switches x 2. When I power off my entire or system or just the switches some cameras have no signal. If I reboot the switches the same or other cameras may power on and are viewable and some are not.

If I input the ip address in a browser I time out. At other times they will connect and provide picture/sound. New CAT 6 wire with new connectors toned and checked about two years ago. I’ve had this issue from day one with previous ipcampower switches as well.

Any ideas?

it definitely sounds like the issue isn’t your cabling or cameras but the switch behavior itself. When cameras randomly come up or don’t come up after a full power cycle, that usually points to one of these:


1. PoE budget instability
Some cheaper PoE+ switches advertise a high port count but don’t actually supply stable wattage across all ports at once. When everything powers up simultaneously, a few cameras get starved and never finish booting.


2. Slow or inconsistent DHCP / ARP tables
If the switch is slow to negotiate links or clear its tables after a reboot, some devices will fail to grab an IP on time and appear “offline” until it retries.


3. Poor inrush current handling
When all the cameras draw startup power at once, lower end switches sometimes brown out individual ports.

For what it’s worth, I eventually gave up on the IPcamPower line for exactly this reason. I’m currently using the GW Security 16 port and 24 port PoE switches in two different setups and have had zero issues with cameras not coming back online after full power cycles. Every port negotiates instantly and the PoE budget is actually stable under full load.


Before replacing hardware, you can try:

• power-cycling modem/router first
• then power the switch
• then the NVR

Sometimes the order matters for cheaper devices.
