It covers the following topics: Before You Begin Package Contents Positioning the Switch Rack-Mounting or Free-Standing...
  • Page 14: Rack-Mounting Or Free-Standing

    Water or moisture cannot enter the case of the unit. Air flow around the unit and through the vents on the side of the case is not restricted (3Com recommends that you provide a minimum of 25 mm (1 in.) clearance).
  • Page 15: Supplying Power To The Switch

    Power problems can be the cause of serious failures and downtime in your network. Ensure that the power input to your system is clean and free from sags and surges to avoid unforeseen network outages. 3Com recommends that you install power conditioning, especially in areas prone to blackout, power dips and electrical storms.
  • Page 16: Checking For Correct Operation

    If these do not resolve the issue: Check the 3Com Knowledgebase for a solution. To visit the 3Com Knowledgebase Web site, start your Web browser, and then enter http://knowledgebase.3com.com. Contact your 3Com network supplier for assistance.
  • Page 17 3CSFP91 SFP (SX) 3CSFP92 SFP (LX) To access the latest list of approved SFP transceivers for the switch on the 3Com Web site, enter this URL into your Internet browser: http://www.3com.com 3Com recommends using 3Com SFPs on the switch. If you insert an SFP transceiver that is not supported, the switch will not recognize it.
  • Page 18: Performing Spot Checks

    At frequent intervals, you should visually check the switch. Regular checks can give you an early warning of a possible failure; any problems can then be attended to when there will be least effect on users. 3Com recommends periodically checking the items listed in Table 1-5. Table 1-5 Items to Check Item Operation Where possible, check that the cooling fan is operating by listening to the unit.
  • Page 19: Automatic Ip Configuration Using Dhcp

    Your DHCP server does not allow you to allocate static IP addresses. For most installations, 3Com recommends that you configure the switch IP information manually. This makes management simpler and more reliable as it is not dependent on a DHCP server, and eliminates the risk of the IP address changing.

    Configuring LLDP LLDP Overview The Link Layer Discovery Protocol (LLDP) operates on the data link layer. With LLDP, a device can store and maintain information about itself and the directly-connected neighbor devices for network administrators to check link status. LLDP Operating Mode LLDP can operate in one of the following modes: TxRx: A port in this mode sends and receives LLDPDUs.
  • Page 86 Item Description Set the interval for sending LLDPDUs. A port operating in TxRx mode or Tx mode sends LLDPDUs to its directly Transmit Interval connected device periodically. By default, the interval is 30 seconds. Set the TTL multiplier. You can configure the TTL of locally sent LLDPDUs to determine how long they can be saved on a neighbor device by setting the TTL hold multiplier.
  • Page 87: Configuring Port-Level Lldp Parameters

    Item Description Set the delay before sending next LLDPDUs. This parameter is introduced to avoid sending excessive number of Send packet Delay LLDPDUs caused by frequent local configuration changes. By default, the delay is 2 seconds.
