Chapter 7 Installing, Removing, and ReplacingAdding, Removing, and Replacing FC I/O BladesScalar i500 User’s Guide 309Read This First:Complete InstallationSteps 7When installing an FC I/O blade, you must follow the installation stepsin this order or communication with the I/O blade and tape drives in thelibrary will not work properly.You may perform the following steps with the library powered on.1 Ensure you are running 400-level firmware or above.2 Save the library configuration (see Saving the Library Configurationon page 329).3 Connect the Ethernet cable from the Library Control Blade to theexpansion module(s). For each FC I/O blade installed in anexpansion module, connect the expansion module containing the FCI/O blade(s) to a port in the Ethernet hub on the LCB (see Figure 21on page 183).• If the FC I/O blade is installed in the bottom bay of the expansionmodule, connect one end of an Ethernet cable to the Ethernet portlabeled Lower in the lower right corner of the expansion module.Connect the other end of the cable to a port in the Ethernet hub on theLCB.• If the FC I/O blade is installed in the upper bay of the expansionmodule, connect one end of an Ethernet cable to the Ethernet portlabeled Upper in the lower right corner of the expansion module.Connect the other end of the cable to a port in the Ethernet hub on theLCB.4 Remove the control path from tape drives that you plan to connect toan FC I/O blade. You must not allow an FC tape drive to serve ascontrol path if it is connected to an FC I/O blade. If you do, theCaution: If you are adding a new FC I/O blade or completelyremoving an FC I/O blade, be sure to read Working WithControl Paths on page 78. If you do not configure controlpaths correctly, you will experience communicationproblems with tape drives, partitions, and the mediumchanger (robot).Note: If the Ethernet cable between the LCB and the expansionmodule is not connected when power is applied to the blade,the blade will hang in the “Booting” state.
