Feature overview

Dedicated 10 Gbps uplink ports
The S3L-24P supports four dedicated 10 Gbps SFP+ uplink ports that deliver speeds 10× faster than traditional 10/100/1000 Ethernet
ports. These transceiver ports can be used to link multiple switches together for uninterrupted, high-speed throughput across the
switches. In addition, they can be used to deliver faster speeds to fiber-compatible devices that are bandwidth intensive, such as an
NAS (network-attached storage) drives.

The S3L-24P 10 Gbps SFP+ ports are backwards compatible with SFP transceivers, allowing you to connect the S3L-24P to an SX Series
1 Gb SFP port.

Compatible SFP+ transceiver modules and fiber optic cables are available through Pakedge. See the Accessories section for more
information.


Pro-AV quick start setup
The S3L-24P supports a quick setup configuration for both IEEE 802.1 AVB and Dante/Q-LAN, ensuring a seamless setup process
for even the most complex AV networks. Typically, the process for configuring Pro-AV technologies can be extensive and require
complicated QoS configurations. The Pro-AV quick setup section provides users the ability to bypass this complexity, greatly reducing
install time.

AVB can be configured on the switch in two easy steps: globally enabling AVB, followed by assigning AVB to specific ports. Similarly,
configuring Dante and Q-LAN requires a simple two-step process: selecting the Pro-AV protocol, followed by assigning the protocol to
specific ports on the switch.

If a network requires the use of more than one Pro-AV protocol, such as the combination of AVB with Dante, the Pro-AV quick setup
smartly adjusts to allow coexistence on the same switch without causing interference between these protocols.

Note: AVB and Dante/Q-LAN can coexist on the same switch, but they cannot operate on a single port at the same time.


IEEE 802.1 Audio Video Bridging (AVB) with Avnu Alliance certification
The S3L-24P is certified with the Avnu Alliance for IEEE 802.1BA Audio Video Bridging (AVB), the IEEE standard that ensures reliable
and timely transmission of audio and video streams across a network. The S3L-24P supports a maximum number of 75 AVB streams,
making it a perfect solution for small AVB environments (recording studios and conference rooms) to mid-sized environments (houses
of worship and restaurants).

AVB eliminates the complexity associated with AV environments by delivering an open, standards-based approach designed to simplify
AV network installation and management. AVB delivers several improvements to the AV network infrastructure, including precise
synchronization, traffic shaping for media streams, admission control, and identification of non-participating devices. AVB saves AV
integrators time and money through simplified configuration and management, improved functionality, and interoperability of AVBsupported AV devices.

The Avnu Alliance is an industry forum that works with member companies to test the interoperability of switches and end devices for
highly reliable delivery of low-latency, synchronized audio across a network and to simplify professional AV system design, installation,
and service.



Advanced switching software
The S3L-24P delivers a comprehensive package of switching protocols designed for projects that require advanced switching
capabilities. The S3L-24P supports Spanning Tree Protocol (STP), including Rapid STP (RSTP) and Multiple STP (MSTP), which allows
large networks with mesh connections to manage duplicate paths between switches, eliminating network loops between switches.
In addition, the switch supports Loop Prevention, a port-based protocol that ensures there are no loops on the switch or devices
immediately connected to the switch. The S3L-24P also supports port mirroring, allowing the ability to mirror traffic from ports, VLANs,
or LAG groups to help in diagnosing network issues.


Layer 3 Lite functionality
The S3L-24P offers certain Layer 3 routing features, including static routing of up to 16 routable interfaces, IGMP snooping v3, IGMP
querier v3, and source-specific multicast. These features are used for passing unicast traffic across VLANs and managing multicast for
the latest media streaming technologies. The S3L-24P supports 64 IP routing entries and 64 IPv4 multicast groups.


Comprehensive security management
The S3L-24P is designed with several enhanced security features, making it ideal for environments where security is a priority. A few of
these enhanced security features include:

• IP Source Guard
• 802.11x and AAA authentication (port level)
• Access control lists and port-based network access control
• ARP spoofing prevention
• DoS and worm attack defense
• MAC filtering and MAC attack defense
• IP filtering

High-end aesthetics with flexible mounting
The S3L-24P fits in a standard 19” rack mount and supports rear- or front-facing mounting. Its sleek, cutting-edge industrial design
exudes an understated elegance that hides the high performance and power within. Its rear port configuration is unique among Layer 3
switches—hiding unsightly cables and providing added security by preventing tampering. Its cool blue LED lights complement existing
AV equipment.


Variable fan for near-silent operation
The S3L-24P is designed for near-silent operation, adding flexibility to placing the switch in locations such as conference rooms and
offices. Designed with careful thermal management, the S3L-24P utilizes variable-speed fans for maximum cooling efficiency and low
noise. The switch is ISO 1779 tested to a max of 42 dBa (average noise level of a library).


Comprehensive GUI
A comprehensive GUI enables incredible control over the powerful features of the S3L-24P switch. Firmware updates, management,
security features, and enhanced configurations are available at the click of a button. Useful diagnostics are displayed directly on the
dashboard, including fan speeds, temperatures, and both RAM and CPU utilization.

BakPak® remote management integration
With the addition of the RK-1 Router or NK-1 Wireless Controller, the S3L-24P can be integrated with the BakPak Network Management
System, allowing you to remotely manage and monitor all of your connected devices, including network audio and video devices, IP
cameras, and networking products. Available BakPak features include remote login and remote power cycling, as well as PoE power
control and self-healing. For more information about BakPak, check out our Dealer Portal.
