Lenovo BladeCenter HX5 1909, Problem Determination And Service Manual

Page: 85 / 313

Notes: If you are going to disassemble a blade server complex and use both blade servers as independent,
stand-alone servers, you must make sure that you have the following components for each blade server:
• A blade server cover
Note: You need a blade server cover for the secondary blade server only if you intend to remove the
scalability tray. You do not need to remove the scalability tray if you are installing both blade servers in
adjacent blade server bays of the same chassis.
• A 1-node speed burst card or a scalability filler
• A hypervisor key for each of the blade servers that you will use in a virtualized environment, if required
If you do not have these components for each blade server, make sure that you order them before you
disassemble a scalable blade complex.
To disassemble a scalable blade complex, complete the following steps.
Step 1. Before you begin, read “Safety” on page v and “Installation guidelines” on page 65.
Step 2. If the scalable blade complex is installed in a BladeCenter chassis, remove it (see “Removing the
blade server from the BladeCenter chassis” on page 66 for instructions).
Step 3. Remove the cover from the topmost blade server (see “Removing the blade server cover” on page
71 for instructions).
Step 4. Stand the blade servers upright on a clean, flat work surface, with the 2-node scalability card facing
up.
Step 5. Remove the 2-node scalability card (see “Removing the 2-node scalability card” on page 83 for
instructions).
Step 6. Press the blade server cover release on each side of the blade server and lift the topmost blade
server from the bottom blade server as shown in the following illustration.
