1. Default Users and Passwords on page 62 You can use one of the following methods to allocate IP information to your Switch essential if you wish to manage your Switch across the network Manual IP Configuration When you configure the IP information the Switch remembers the information that you enter until you change it again You should use the Manual IP configuration method if you do not have a DHCP or BootP server on your network or you want to remove the risk of the IP address ever changing or m your DHCP or BootP server does not allow you to allocate static IP addresses Static IP addresses are necessary to ensure that the Switch is always allocated the same IP information 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 or BootP server and eliminates the risk of the IP address changing To manually enter IP information for your Switch work through the Manually Configuring IP Information section on page 49 Automatic IP Configuration via DHCP By default the Switch tries to configure itself with IP Information without requesting user intervention It tries to obtain an IP address from a DHCP server on the network When using automatic IP configuration it is important that the IP address of the Switch is static otherwise you will not know what the IP address is and it will be

Switch does not need an AC supply and the resiliency is provided by the DC supply This is useful in an environment where only DC power is available The RPS provides three main benefits to the customer Power Redundancy if a Switch is powered from the mains supply unit a fallure of the internal power supply will cause the Switch to fail This can be overcome by connecting both the AC and DC RPS supplies to the Switch Additional redundancy can also be added to the DC power by using N 1 DC power supplies to further increase the availability of the system Uninterruptible Power the system allows easy connection and maintenance of batteries to the RPS shelf to further increase the availability of the system Additional Power to PoE Ports the internal AC Power Supply of a PoE Switch can provide enough power for most network applications The RPS can be used to supplement additional power up to a maximum of 15 4W including full backup of all PoE devices on the network Table 8 below outlines the behavior of the Switch when changes occur to the power system such as removing the AC mains cable when the RPS is attached The responses to the different power inputs are controlled by the Switch s internal power supply and not by the RPS 30 CHAPTER 2 INSTALLING THE SWITCH Specifying the Redundant Power System gt Table 8 Switch Power Inputs Power Input before Power Input after User Intervention User Intervention
