Cisco Catalyst Digital Building Series Switch Highlights

● 8 fast Ethernet ports and 2 gigabit copper uplink ports, with line-rate forwarding performance

● Universal Power over Ethernet (Cisco UPOE) and Power over Ethernet Plus (PoE+) support with up to 480W of power budget.

● Support for Layer 2 features, optimized for robust connectivity to lighting and other building IoT devices.

● Silent operation due to fanless design, which enhances reliability

● Enhanced Limited Lifetime Warranty (E-LLW)

Cisco Catalyst Digital Building Series Switch Models and Default Software

The Cisco Catalyst Digital Building Switches are available in two switch models. They vary by the output power/port supported by the model. One model supports Power over Ethernet Plus (PoE+), which guarantees 30W/port of power. The other model supports Universal Power over Ethernet (UPOE), which guarantees double the power, 60W/port.

Embrace Efficiency and Lower Costs with Cisco Digital Building Series

The Cisco Catalyst Digital Building Series Switches are industry’s first ever purpose-built switch designed for low-voltage LED lighting and digital building systems. The switch can be used to power devices and applications with Cisco’s perpetual and fast Universal Power over Ethernet (UPOE) technologies, delivering up to 60W/port.

The Cisco Catalyst Digital Building Series Switch offers several benefits that no other competitive switch in the market does:

• Flexible deployment with semiruggedized, plenum-rated, UL-certified fanless features, multiple powering options, and support for mobile apps for easy deployment

• <0.5W power consumption on standby, Uninterrupted power during reboots and rapid power restoration under 5 seconds after power resumption

• High security and reliability with long-lasting 10+ year system life and threat sensing and mitigation when used with Catalyst 3850 upstream switches.

• Functional interoperability with CoAP proxy support, a lightweight protocol for constrained devices: lights, VAV systems, digital signage, sensors, and so on.

Mobility Express Deployment Supported Cisco Aironet Access Points

April 19 2017 , Written by Cisco & Cisco Router, Network Switch Published on #IT, #Cisco Wireless - Cisco Wireless AP

In a Cisco Mobility Express network, Access Point (AP) running the wireless controller function is designated as the Master AP. The other Access Points which are managed by this Master APare referred as Subordinate APs.

NOTE: In this article, Mobility Express refers to the Cisco 1800 series Access Point which supports the controller functionality. It is referred to as Master AP.

The Master AP has two roles:

1. It functions and operates as a wireless LAN controller to manage and control the Subordinate APs. The Subordinate APs operates as lightweight access points to serve clients.

2. Master AP operates as an Access Point to serve clients

Supported Cisco Aironet Access Points

Access Points which support the Mobility Express controller function capability are listed in the following table:

Table3: Access Points supporting Mobility Access (Master APs)

The Main Differences between the AP 2800 and AP 3800 Access Points

April 18 2017 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP, #IT

The Cisco 2800 and 3800 Series Access Points target customers requiring support for mission-critical and best in class applications.

The 2800/3800 embodies ClientLink 4.0, an innovative antenna technology comprising four transmit radios and four receive radios called 4x4 in a Multiple Input Multiple Output (MIMO) configuration and supporting three spatial streams (3SS), together referenced as 4x4:3. Using this type of antenna system along with additional Modulation Coding Scheme (MCS) rates supporting up to 256 QAM and up to 160 MHz channel bonding, rates of up to 5 Gbps can be supported.

ClientLink 4.0 uses these features along with an additional antenna (N+1) to allow for beam-forming for all 802.11a/g/n/ac and now ac Wave-2 clients including those supporting 3 spatial streams.

Multigigabit Ethernet

MultiGigabit Ethernet, also known as MGig or NBaseT, provides multiple gigabit uplink speeds of 2.5 Gbps and 5 Gbps in addition to 100-Mbps and 1-Gbps speeds. All speeds are supported on Category 5e cabling for an industry first, as well as 10GBASE-T cabling. This is huge achievement which can result in significant cost savings for large campus network. No longer are you constrained to 1Gbps, nor do you have to worry about running new cabling in order to support the new speeds.

Cisco Catalyst Multigigabit technology solves these challenges on their newer Catalyst 3850, 4500E and 3560-CX switches, with the 3800 Series access point taking full advantage of the single-wire MGig connection. This is an incredibly important consideration for 802.11ac Wave 2 implementations, and should be reviewed before any deployment.

Peter Jones, Principle Engineer with Cisco and NBASE-T Alliance chair, gave an impressive presentation at TFDX earlier this year, detailing the technical achievements engineered to overcome this obstacle of capacity.

Expansion Module Slot

The 3800 Series AP sports a module port for future expandability. Physical modules can be fitted for value-adds like advanced security or hyperlocation technologies.
