  • Page 4: Fcc Notice

    SAFETY INFORMATION CLASS 1 LASER TRANSCEIVERS The VH-8G 8-port switch uses Class 1 Laser transceivers. Read the following safety information before installing or operating these modules. Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This control loop eliminates the need for maintenance checks or adjustments.
  • Page 5 Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye hazard. When viewing the output optical port, power must be removed from the switch. WARNING: FIBER OPTIC PORT SAFETY When using a fiber optic port, never look at the transmit laser while it is powered on.

Instructions for making connections and powering up the switch are provided as well. Appendix A. Technical Specifications: Provides a list of standards compliance and certifications as well as physical and operational specifications.

  • Page 15: Product Overview

    Feature Summaries • Application Example Description This installation guide describes Enterasys’ VH-8G Gigabit Ethernet switch. This switch provides 8 1000Base-SX ports and includes an SNMP-based management agent with support for both in-band and out- of-band access for managing the switch.

    Front Panel Figure 1-1 shows the front panel of the Enterasys VH-8G. Table 1-1 defines the VH-8G front panel components. Table 1-1. Front Panel Components Name Power LED RPU LED Link LEDs Activity LEDs Reset Button 1000Base-SX SC ports 9033639 Figure 1-1.

  • Page 18: Rear Panel

    The VH-8G switch is fully compliant with IEEE 802.1D transparent bridging specifications. An address table is provided for learning, filtering, and forwarding. The switch can support up to a maximum of 12K addresses. Addresses are automatically learned by the switch, and can be individually assigned specific forwarding treatment by the network administrator if desired.

  • Page 19: Spanning Tree Protocol

    To minimize the possibility of dropping frames on congested ports, the VH-8G switch provides 1 MB of frame buffering per port. This buffer space is used to queue packets for transmission on congested networks. This is an additional advantage over cut-through switching technology, which drops packets immediately when experiencing collisions.

  • Page 20: Configuration And Management Interfaces

    Configuration and Management Interfaces The VH-8G switch can be managed using any of the following methods: • Serial console, out-of-band An RS-232 connection, using a DB-9 connector, is included on the switch’s rear panel for system management. Serial console management can be performed out-of-band by directly connecting a terminal or computer running communications software to the RS-232 port on the switch.

  • Page 21: Port Mirroring

    The switch port LEDs provide a quick and accurate display of the integrity of switch connections. Each SC port has a Link and Act LED. The Link LED indicates a valid 1000 Mbps connection or if the port has been disabled.

  • Page 22: Virtual Lans (Vlans)

    The VH-8G allows up to four ports to be joined together as a trunk. Up to four port trunks on a single switch can be configured. Each trunk can combine two, three, or four ports, creating an aggregate bandwidth of up to 8Gbps.

  • Page 24: Application Examples

    The VH-8G switch is ideal for meeting the needs of today’s high performance networks. The switch is designed to consolidate your network core providing high-bandwidth connections between workgroup switches and server farms.

  • Page 25: Client/Server Network Application

    Client/Server Network Application To improve workstation performance in a client/server environment, the VH-8G switch can be configured to provide 2 Gbps full-duplex Gigabit Ethernet connections to servers by connecting each to a dedicated switch port (Figure 1-3). Users can be accommodated through connections to other switches with 1000 Mbps uplinks, or through direct connections.

  • Page 26: Backbone Consolidation Application

    (Figure 1-4). Workgroup switches are provided with a single connection to the VH-8G while servers are put on dedicated ports. The gigabit fiber links allow the switch to connect to a remote location, such as another building floor or a separate building.
