==========================================
The Switch will come with Rack Mounts, AC Power Cord and Console Cable.

OVERVIEW
The 3Com® Switch 4200 family provides wirespeed 10/100 stackable switching with easy-to-use features perfect for cost-consciousmedium-sized businesses needing basic access and distribution. These fixed-configuration switches support enterprise-class QoS, security and stackable scalability with single IP address management. All models come with two copper 10/100/1000 ports for built-in stacking or downlink ports; one model also has two additional SFP mini-GBIC slots for added copper or fiber connection flexibility.

DELIVERS AFFORDABLE ENTERPRISE:CLASS FEATURES
3Com delivers superior business value by offering enterpriseclass solutions without the complexity. These stackable switches provide wirespeed performance, QoS, VLANs, security and resiliency features.

Easy setup Minimizes installation expense
With a fixed configuration format, the Switch 4200 is fully plug-and-play—designed to operate out-of-the-box with the minimum amount of user configuration. Auto-negotiation and auto-MDIX detection make it simple to install while automatic IP allows the switch to configure its own IP settings by negotiating with industry-standard DHCP or BOOTP servers.

Provides security and resiliency
The Switch 4200 provides IEEE 802.1X Network Login and RADIUS Authenticated Device Access (RADA) security, and resiliency features such as Rapid Spanning Tree Protocol and IEEE 802.3ad Link Aggregation (LACP) for Gigabit ports.

ENHANCES MANAGEMENT AND CONTROL
The Switch 4200 family is easy to use and manage, designed to increase business productivity by reliably supporting business applications. Stack together up to four devices for easy administration, with single IPmanagement. 3Comnetwork management software offers comprehensive support, including 3Com Network Director for an enterprise standalone solution or 3Com Network Supervisor for smaller networks.

CONNECTORS
26-port, 24 auto-negotiating 10BASE-T/100BASE-TX ports configured as auto-MDI/MDIX, and 2 auto-negotiating 10BASE-T/100BASE-TX/1000BASE-T ports configured as auto MDI/MDIX.
