Configuring Wake on LAN

You can use the management module to configure Wake on LAN for blade servers that support this feature. See the documentation for your blade server for further information.

1. Write down the MAC address of the integrated Ethernet controllers in each blade server. You can find this information in one of the following ways. The MAC addresses are needed to configure a remote system to start the blade servers through the Wake on LAN feature: the remote system issues the Wake on LAN command (a Magic Packet frame) by sending it to a MAC address.
   • Blade server MAC addresses are part of the Vital Product Data (VPD) that the management module maintains for each installed blade server. (Go to Monitors → Hardware VPD in the management-module Web interface and view the section related to blade server hardware inventory. Click the module name of a particular blade server to access the blade server VPD data page. On this page, select the Ports tab at the top to view the MAC address information.
   • The MAC address is listed on the bar code label that is on the bottom of each blade server enclosure. Each blade server might also have a loose label on which the MAC addresses are printed.
   • For some blade server types, you can read the MAC address by using the blade server Configuration/Setup Utility program (Devices and I/O Ports → System MAC Addresses)
2. Make sure that the Wake on LAN feature is enabled in the BladeCenter management module (Blade Tasks → Power/Restart and Blade Tasks → Configuration in the management-module Web interface).
3. Make sure that the external ports of the Ethernet switch modules or pass-thru modules in I/O-module bays 1 and 2 are enabled (I/O Module Tasks → Admin/Power/Restart → I/O Module Advanced Setup in the management-module Web interface). If the external ports are not enabled, blade servers in the BladeCenter unit will not be able to communicate with the external network.
