Replace ExpressModule (Sun Blade 8000 Chassis)

PCI Express ExpressModules (EMs) are supported in the Sun Blade 8000 Chassis only. If an EM fails or if you choose to change the I/O configuration, you will need to replace an EM. You can remove and replace an EM from a powered-on Sun Blade 8000 Chassis using a hot-plug procedure, as well as from a powered-off chassis. If you are not immediately replacing the EM, you must install an EM filler panel to meet FCC limits for electromagnetic interference (EMI).

The EMs are customer-replaceable units (CRUs).

Note

Some operating systems, and some PCIe ExpressModules (EMs) and Network Express Modules (NEMs) do not support a hot-plug operation. Check your operating system documentation, the I/O module documentation, and the Sun Blade 8000 Series Product Notes to verify the hot-plug support.

About ExpressModule to Blade Connections

A pair of EMs is assigned to each blade in the chassis. All EMs connect to a chassis midplane. The midplane provides an interconnect between the blades and the EMs installed in the chassis. The midplane connections between the blade and the EM are logically defined by the midplane as shown in the following table.

Removing an ExpressModule

  1. Identify which EM in the chassis to replace.

    If the amber Attention indicator on an EM is lit, this indicates a problem with the EM. Otherwise, if you want to change the I/O configuration, you can choose any EM to replace.

  2. If you are hot-plugging the EM, press the Attention button to prepare the operating system.

    EMs cannot be prepared for hot-removal through the ILOM interfaces.

  3. Verify that the EM Power indicator is Off.

    If you have successfully prepared the EM for a hot-remove, the Power indicator goes out.

  4. Press down on the ejector lever at the top of the EM to release the latch.

  5. Swing down the ejector lever so that it is perpendicular with the front of the EM and slide the EM out of the chassis.

Installing an ExpressModule

  1. Before you install a new Gigabit Ethernet EM, locate its MAC address, which is visible on the EM with its cover removed. Press the Release button on the side of the GbE EM to release its cover, then remove the cover.

    Record the MAC address and the slot number into which you are about to install the GbE EM. Keep the data for future reference. Replace the GbE EM cover by sliding the cover into place. This step does not apply to a Fibre Channel or InfiniBand EM.

  2. Align the EM with the vacant EM slot.

    Ensure that the EM indicator LEDs on the front panel are facing toward you, and that the EM ejector lever is at the bottom and is fully open.

  3. Align the EM with the chassis guidance system and slide the EM into its slot.

    Ensure that the EM engages with the chassis guidance system. Failure to align the EM correctly can result in damage to the EM's internal connections to the chassis midplane.

  4. Push up the EM ejector lever and close the lever to secure the EM in its slot.

  5. After you physically install the EM in its slot, press the EM Attention button to notify the operating system that a new EM is installed.

  6. Verify that the EM Power indicator is On.

    If the hot-insert procedure was successful, the green Power indicator will illuminate.
