any reviews/comments for CRS328-24P-4S+RM or CRS112-8P-4S-IN poe switches

Mon May 21, 2018 7:22 pm

anybody has installed CRS328-24P-4S+RM or CRS112-8P-4S-IN new poe switches. any review or comments about them.
i am asking this because they are new products with poe support and i want to be sure they are working 100% flawless.
i want to power 16 and 20 rbwaps per building block.
why european resellers says that is only 1 year warranty. isnt 2 years in electronics by european union?

i have one CRS328-24P-4S+RM here in my lab preparing it for installation next week. i ordered this model because of its 4 sfp+ ports. its not the poe feature which is needed. the device makes a very good impression.

i received mine and i use it mostly to power up rbwap's. installed it to customer and for the moment i am very satisfied with this purchase. temperatures are low (compare to another brand). i use routerOS.
i would like a 16 poe port version also.
so is it 1 or 2 years european warranty?

I would also like to ask question regarding the crs328, Anyone had tried using this device to power Hikvision CCTV (PTZ, Bullet, Dome and/or Fish eye) IP camera? does it work? I tried using crs112 (PoE Version) but I failed to power the cctv thus on the Switch's interface it shows short circuit. Thank you

I have massive performance problems with the CRS112. See viewtopic.php?f=2&t=135509&sid=52293568 ... f948612c33
But it was the only switch with fiber, PoE and 8 ports that fits into a 10"-rack...

I have CRS112-8P-4S-IN it works more or less fine. To power some other devices (e.g. RB450G and thirdparty webcam) I had to set the port's POE status to force-on).

I have it installed into 19'' rack using included "ears": Image

Hoverer I'd like to put two of these switches in a row within single rack unit, but that's not possible with included ears, despite there is available space. Any advice?

I've had my CRS328 racked and in production now for > 30 days.

I'm currently powering 10 SBCs (with POE splitters) and a number of ruckus APs, hexs, and hexpoes that are then powering hexs and ruckus APs. I have two outdoor ruckus APs, one of which is also powering a camera from the poe out port. After collecting 24 hours of 1 sec samples the max power for the outdoor AP + camera was 25.9W. Mean was around 14W.

I have tested 3 OS/firmware updates (routeros and routerboard) with zero power loss to connected devices (uptimes confirmed on APs, switches, and SBCs).

I have been able to shutoff and restore power remotely to devices.

My only two (current) criticisms:

1. The fan keeps cycling on and off. It's in a rack in a utility room, so none hear it, but I'm concerned about fan failure if it constantly starts up, runs for a min, then is down for a min, then repeat. I'd like an option to just keep the fan running.
2. The top row of LEDs are so bright that the "red" led to indicate 57V bleeds over to the next vacant LED indicator spot, so you have to check if something is in the port or not. If you connect a low volt passive device like a hex, then its green with no bleed over that I can tell, however if there is a red next to the green, the green is then yellow (red+green light = yellow). I guess, its just sloppy design, but if corners cut there, where else are corners cut?

That all said, I'm going to get a 2nd CRS328 as a backup. I have 16 POE devices connected to this replacing a midspan. I'd rather not go back to using a midspan (too many cables). The most important features (do not cut power on OS/firmware upgrades, remote power management, network performance, manageability, etc...) are all there.

Feature request for all POE products:

1. Please add the ability to also graph power usage for the device and per port.
2. Models with redundant power and fans.

We purchased a couple of CRS112-8P to test for sites that have both 24v and 48v kit. Many of these sites are solar powered so I needed to test power consumption. What we noticed which was strange was that when we tried to pass 56v to it from a Hex PoE switch it would not boot and the Hex reported overload. Stramge considering the Hex at this voltage should be good to around 25W but the docs for the CRS112-8P state max power consumption of only 10W. CRS had no devices connected during the test and port from Hex tested by powering an RB1100AHx4 without issue kinda suggests these draw much more power than the specs suggest.
