Cisco 4-port 10/100 Ethernet switch HWIC-4ESWThe 4 and 9 port Cisco EtherSwitch 10 100 high speed WAN interface cards (HWICs) supported on the Cisco 1800 (modular) 1941, Cisco 2800 2900, and Cisco 3800 3900 series integrated services routers offer small to large size businesses and enterprise branch office customers the option to integrate switching and routing in one device.

The 4- and 9-port Cisco® EtherSwitch® 10/100 high-speed WAN interface cards (HWICs) supported on the Cisco 1800 (modular)/1941, Cisco 2800/2900, and Cisco 3800/3900 series integrated services routers offer small-to-large-size businesses and enterprise branch office customers the option to integrate switching and routing in one device. This combination offers ease of configuration, deployment, and management while using the powerful characteristics of Cisco routing and Cisco Catalyst® switching features.
The modular 4- and 9-port Cisco EtherSwitch HWICs provide line-rate Layer 2 switching across Ethernet ports using Cisco IOS® Catalyst Software. The 4-port Cisco EtherSwitch HWIC has four 10/100 switched Ethernet ports, with options for inline power support on all four ports. The 9-port Cisco EtherSwitch HWIC has nine 10/100 switched Ethernet ports, with options for inline power support on 8 of the 9 ports. The ninth port does not support inline power but can be used as a regular switch port for trunking and other normal data applications. Features such as port autosensing, quality of service (QoS), VLAN support from 802.1P and 802.1Q standards, and 802.1D spanning tree protocols are standard on the Cisco EtherSwitch HWIC. The Cisco EtherSwitch HWICs are available in standard 4- or 9-port 10/100BASE-TX switch HWIC and Power-over-Ethernet (PoE) configurations. The PoE configurations consist of a 4- or 9-port 10/100BASE-TX switch and a 4- or 8-port inline power module daughter card. The power module daughter card houses a power controller for detecting, classifying, and enabling power on 802.3af-compliant powered devices attached to the HWICs. The inline powered version of the Cisco EtherSwitch HWIC can power Cisco IP phones, Cisco wireless access points, or any other IEEE 802.3af-compliant device. The optional inline power support on the 4- and 9-port HWICs on the Cisco 2800/2900 and Cisco 3800/3900 series of integrated services routers requires the use of a field-replaceable inline power supply. (Refer to Figure 1.)

Insulation and outside cover materials tough to cut and strip.
Size: 30ft, Style: 10 Gauge
Made in China. Wire works fine but the materials used for insulation and the outer cover are a pain to separate and strip for use. This isn’t like Ancor wire!

Well worth it, Cost efficient and heavy duty! don't hesitate just buy!!
Size: 100ft, Style: 14 Gauge
Very nice and durable wire. well insulated, neatly wrapped and held secure in roll with velcro straps and wire is flexible enough but at the same time sturdy for any job. Wire strippers had no problem pulling insulation coat off. all 100 foot of wire was used on a new pontoon build and will be ordering more from these guys. If you are looking at a couple options of which wire will do you the best look no further and hit BUY NOW!

My Denon ROCKS
Style: AVR-X3800H
Pros:
Nine Amps power a 9.1 or 7.1.2 or 5.2.4 speaker configuration because most of us want Atmos to work in our listening room.
Plenty of power available in each amp and each configuration
Atmos DTS IMAX plus any other codec or audio visual enhancement is available. Yes, 4K 8K HDR all supported.
Three HDMI outputs
Preamp output for up to 11 channels so any combination of preamp vs. power amplifier output is available. But not both preamp AND power amp for the same channel. And you can pick and choose which channel you want for pre amp vs power amp individually. So it can function as a AV Preamp Processor at very reasonable price point.
DAC (changes Digital Signal to Analog) with all the power amplifiers you could want. High quality, including DSD, is an added bonus.
Setup customizable to the nth degree. Some people might say too many options but that’s the way we get this AVR to meet our individual requirements
I’ve been working with the setup for the last week and have dialed in for my needs. Still playing with the HEOS but I think it’s working well for now. Various HDMI inputs need different surround settings, I like the DTS best, but the unit has a way to include default settings for each HDMI. I’ll use default settings with my BluRay. And I’ll use direct or pure or whatever the source allows for music and streaming. And most users will want a streaming stick like the Amazon one otherwise you can’t get the Atmos signal to work. Older streamers won’t pass the Atmos signal though.
The only problem with a device like this is you will buy more speakers and amps and possibly even more subwoofers, the unit will support 4 subwoofers. Enjoy
So I will get back to you with comments about longer term issues. BTW the 3800 was a refurbished version for $999 . Definitely an excellent value. The online reviews are quite favorable. Even the audiophiles are still learning the nuances of setup. It’s worth the extra effort to get the most out of each user’s individual existing equipment.
Cons: None. I’ve been an audio video nerd for decades so I can say that the setup effort is easily justified once the user, with user manual in hand, patiently works out the desired configuration. The audio expert online information is invaluable.
I have 21MBS broadband service in my region. Even with this limitation I have more than enough added capacity with the Denon that I would never return it to seller unless someone catastrophic happened. Yes I like it that much.
