30 CHAPTER 4: C ONFIGURING THE S WITCHsticker on the base of the Switch. This sticker containsthe MAC address and default IP address of the Switch.To detect its IP information using the automatic config-uration process, the Switch goes through the followingsequence of steps:1 The Switch tries to configure itself with the default IPaddress 169.254.x.y, where x and y are convertedfrom the last two bytes of its MAC address.For example, if the MAC address were 08004E000102,the IP address would be 169.254.1.2. This address isused if the Switch is operating in a standalone mode, orno other switches on the network have this IP address.The Switch also assigns the subnet mask 255.255.0.0(default class B mask) to itself.2 If this default IP address is already in use on thenetwork, then the Switch detects this, and incrementsthe last byte of the MAC address by one to generate itsIP address.The IP address would therefore become 169.254.1.3.3 The Switch repeats step 2 until an unused IP address isfound.3Com recommends using automatic IP configurationonly for the initial setup. Once you gain access to theconsole, you should assign an IP address to the Switch(either by using DHCP or assigning a static IP address) toensure successful communication between the Switchand other network devices.Setting the IP AddressTo set the IP address for the Switch:1 On the menu, click IP Settings.
