Does the XGS1250-12 have/use active cooling?

@Zyxel_Nami

Here's the current state of both switches:
(All readings are in Degrees Fahrenheit)

XGS1250-12 in Service Closet:
Ambient Room Temp: 70.2
Port 1 Temp: 94.6
Heat Sink (Center) Temp: 96.7
Port 12 Temp: 97.0
Active Ports: 1, 9-11
Ports 9 and 10 = 5Gbps to Zyxel PoE++ Injectors
Port 11 = 10Gbps, Cross-Connect to HDC (Length = 48 feet)
Port 12 - Inactive, no SPF+ module inserted.

XGS1250-12 in Home Data Center
Ambient Room Temp: 71.6
Port 1 Temp: 97.2
Heat Sink (Center) Temp: 98.0
Port 12 Temp: 98.3
Active Ports: 1-7, 11-12
Ports 1-7 = local devices at 1Gpbs
Port 11 = 10Gpbs, Cross-Connect to Service Closet (Length = 48 feet)
Port 12 = 10Gbps, passive twinax DAC to Intel X710-DA2 port on pfSense firewall

Both switches are in well-ventilated areas and in open racks, not stacked. Operational temperatures using the v1.00 firmware were in the 113-118 Degree range. Updating to v2.00 firmware lowered those operational temperatures to the 103-106 Degree range. Additional passive cooling has further lowered those operational temperatures to those enumerated above. I would like to suggest that future firmware updates expose any and all temperature sensors outputs in the user interface, perhaps in an "Advanced" tab, and the inclusion of SNMPv1 and port labeling would be welcomed additions. (I'm a network and systems engineer of almost 40 years. Most residential users would never care but I take an interest in how my gear is going to perform long-term and operational temperature is a large part of that.)

This post was not intended as a dig on the switch. I very much like the switch and the Zyxel Team is coming up with some fantastic designs and implementations right now. I hope to eventually lay hands on an XS1930-10 and an XS1930-12HP (once the prices float down a little) to review for use in high-end residential and low-end data center roles. I also very much love the Zyxel WAX650S APs, so much so that I can easily overlook paying $54 for the PoE++ Ethernet injectors. They're just that good. They even made me retire a perfectly good WAX620D-6E. So thanks to all involved for pushing the state of the art forward. It is appreciated.

If you would like any additional data on environment or use please reach out to me, I'll be happy to assist wherever I can.

And thank you so much for the response. I look forward to future firmware improvements.

@Zyxel_Nami As far as temperature sensor data goes, what you present or log within any switch gear kind of depends on which temperature sensors you have, where, and how many. Presenting current fan speed and any/all temp sensor data would be useful (so long as it's properly labeled) for long-term tracking via SNMP as well as random spot checking by the user in the web UI. Without knowing specifics of the architecture I would be hard pressed to pick the top data points of interest or why. Generically, I would guess that fan speed, CPU temp, and air intake and outflow points would be the top points of interest. Thanks again. Your attention to this discussion is appreciated.

I use both a stand-alone infra-red thermometer and a Fluke thermal imager that's normally used for real data centers (at least the one I frequent). In a previous post I've discussed exposing thermal sensors to the web UI as well as SNMP support with Zyxel Community Support mods. Both switches are doing okay so far; no zombies or unscheduled reboots so I'm happy about that. The three WAX650S APs are all pretty solid (using local admin) as well. I've since bought two more 1250s for work, to solve a "front-of-house/back-of-house" transport issue and it's pretty amazing how tolerant the new silicon is of older Cat 5E. I can still get a 10Gb link on a 60 foot run that's 25 years old, and I can prove it with tools and traffic graphs I have at hand. We'll see what future firmware updates look like for added features. These switches and APs also support ReoLink IP security cameras well (with their 60W PoE++ injectors) and that's sort of become my combination of choice for overnight video surveillance. That said, I'm also looking forward to trying out the XS1930s in a couple of racks in the data center, as redundancy for the already dual-redundant Avaya VPS7K 10GbE switches (because losing five NAS disk subsystems on a virtualization stack with hundreds of VMs is a special kind of pain). Anyway, thanks for the additional comments. Finding common ground on how tech toys perform is useful to me.
