Juniper EX2300 Switches for Lenovo with Power over Ethernet

The Juniper EX2300-C-12P and EX2300-24P Ethernet switches for Lenovo with Power over Ethernet (PoE) deliver a compact, high-density, cost-effective solution for small network environments where space and power are at a premium. Featuring a small, 1U footprint, these switches are ideal for access-layer deployments in micro branches, retail and workgroup environments, and converged network access in larger networks.

The EX2300-C-12P offers 12x 10/100/1000BASE-T ports in a single platform, while the EX2300-24P offers 24x 10/100/1000BASE-T ports. Both models offer Power over Ethernet (PoE) for powering attached network devices, such as such as telephones, video cameras, IEEE 802.11ac WLAN access points, and videophones. Optional front panel 10GbE uplink ports support connections to higher-layer devices.

The EX2300 switches support L2 switching protocols as well as L3 routing protocols like RIP and static routing that are included in the base license. An enhanced license is available via special bid for supporting additional L3 protocols such as OSPF, Internet Group Management Protocol (IGMP v1/v2/v3), Protocol Independent Multicast (PIM), and Virtual Router Redundancy Protocol (VRRP), as well as IEEE 802.1 Q-in-Q VLAN tunneling.

The EX2300 switches are shown in the following figure.

Figure 1. Juniper EX2300-C-12P (top) and EX2300-24P (bottom) switches

The EX2300 switches are designed with non-blocking, line-rate throughput and zero oversubscription.

The compact PoE-enabled EX2300-C-12P switch can simultaneously deliver up to 15.4 watts of standards-based 802.3af Class 3 PoE to a maximum of 8 ports or 30 watts of standards-based 802.3at PoE+ to a maximum of 4, based on a total system budget of 124 W.

The PoE-enabled EX2300-24P switch can simultaneously deliver up to 15.4 watts of standards-based 802.3af Class 3 PoE to a maximum of 24 ports or 30 watts of standards-based 802.3at PoE+ to a maximum of 12 ports, based on a total system budget of 370 watts.

Low power consumption, low acoustic fans (EX2300-24P) or fanless design (EX2300-C-12P), and a small footprint enable flexible, environmentally friendly deployment.

The EX2300 switches are considered particularly suited for the following customers:

• Customers who are implementing Power over Ethernet (PoE) standards for supporting networked devices such as telephones, video cameras, IEEE 802.11ac WLAN access points, and videophones in converged networks
• Customer who need economical network connectivity solution for access layer deployments in branch and remote offices, as well as enterprise campus networks
• Customers who want to use GbE in their infrastructure (servers and networking)
• Customers who are implementing a virtualized environment and require multiple GbE ports
• Customers who require investment protection for 10 GbE ports
• Customers who want to reduce total cost of ownership (TCO) and improve performance while maintaining high levels of availability and security
• Customers who want to avoid oversubscription, which can result in congestion and loss of performance
• Customers who want to implement a converged infrastructure with NAS or iSCSI

The EX2300 switches offer the following key features and benefits:

• Increases network performance

  The EX2300-C-12P switch provides up to 64 Gbps of switching throughput and supports two SFP+ 10 Gb uplink ports for zero oversubscription, and the EX2300-24P switch provides up to 128 Gbps of switching throughput and supports four SFP+ 10 Gb uplink ports for zero oversubscription.

• Converged environments

  The EX2300 switches provide the highest levels of flexibility and features in its class for the most demanding converged data, voice, and video environments, delivering a reliable platform for unifying enterprise communications.

  By providing PoE to VoIP telephones, videophones, closed-circuit security cameras, wireless access points, and other IP-enabled devices, the EX2300 switches deliver a future-proofed solution for converging disparate networks onto a single IP infrastructure.

  To ease deployment, the EX2300 switches support the industry-standard Link Layer Discovery Protocol (LLDP) and LLDP-Media Endpoint Discovery (LLDP-MED) protocol, enabling the switches to automatically discover Ethernet-enabled devices, determine their power requirements, and assign virtual LAN (VLAN) membership.

• High availability

  To avoid the complexities of the Spanning Tree Protocol (STP) without sacrificing network resiliency, the EX2300 employs a redundant trunk group (RTG) to provide the necessary port redundancy and simplify switch configuration. It also supports cross-member link aggregation, which allows redundant link aggregation connections between devices in a single Virtual Chassis configuration, providing an additional level of reliability and availability.

• Security

  Working as an enforcement point in Access Policy Infrastructure, the EX2300 switches provide both standards-based 802.1X port-level access control for multiple devices per port, as well as Layer 2-4 policy enforcement based on user identity, location, device, or a combination of these.

• Virtual Chassis Technology (Requires Enhanced Features license; special bid only, not available as a field upgrade option)

  The EX2300 switches support Juniper’s unique Virtual Chassis technology, enabling up to four interconnected EX2300 switches to be managed as a single logical device, delivering a scalable, pay-as-you-grow solution for expanding network environments.
