Down and Removing Power From the Server. Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance. Caution If you cannot safely view and access the component, remove the server from the rack. Remove the top cover from the server as described in Removing the Server Top Cover. Step 2 Remove the mRAID riser (riser 3) from the server: Using both hands, grasp the external blue handle on the rear of the riser and the blue finger-grip on the front end of the riser. Lift the riser straight up to disengage it from the motherboard socket. Set the riser upside down on an antistatic surface. Step 3 Remove any existing card from the riser: Disconnect cables from the existing card. Open the blue card-ejector lever on the back side of the card to eject it from the socket on the riser. Pull the card from the riser and set it aside. Step 4 Install a new card to the riser: With the riser upside down, set the card on the riser. Push on both corners of the card to seat its connector in the riser socket. Close the card-ejector lever on the card to lock it into the riser. Step 5 Return the riser to the server: Align the connector on the riser with the socket on the motherboard. At the same time, align the two slots on the back side of the bracket with the two pegs on the inner chassis wall. Push down gently to engage the riser connector with the motherboard socket. The metal riser bracket must also engage the two pegs that secure it to the chassis wall. Step 6 Reconnect the cables to

At the same time, align the two slots on the back side of the bracket with the two pegs on the inner chassis wall. Push down gently to engage the riser connector with the motherboard socket. The metal riser bracket must also engage the two pegs that secure it to the chassis wall. Step 6 Replace the top cover to the server. Step 7 Replace the server in the rack, replace cables, and then fully power on the server by pressing the Power button. Step 8 If your server is running in standalone mode, use the Cisco UCS Host Upgrade Utility to update the controller firmware and

The rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance. Caution If you cannot safely view and access the component, remove the server from the rack. Remove the top cover from the server as described in Removing the Server Top Cover. Use two hands to grasp the external riser handle and the blue area at the front of the riser. Open the hinged, plastic card retainer that secures the rear-panel tab of the card. Pull evenly on both ends of the HHHL form-factor NVME SSD to remove it from the socket on the PCIe riser. If the riser has no SSD, remove the blanking panel from the rear opening of the riser. Step 2 Install a new HHHL form-factor NVME SSD: Open the hinged, plastic card retainer. Align the new SSD with the empty socket on the PCIe riser. Push down evenly on both ends of the card until it is fully seated in the socket. Ensure that the SSD’s rear panel tab sits flat against the riser rear-panel opening and then close the hinged card retainer over the card’s rear-panel tab. Position the PCIe riser over its two sockets on the motherboard and over the chassis alignment channels. Carefully push down on both ends of the PCIe riser to fully engage its two connectors with the two sockets on the motherboard. Replace the top cover to the server. Replace the server in the rack, replace cables, and then fully power on the server by pressing the Power button. Figure 11.

Server Top Cover. Remove any cables from the ports of the PCIe card that you are replacing. Use two hands to grasp the external riser handle and the blue area at the front of the riser. Lift straight up to disengage the riser's connectors from the two sockets on the motherboard. Set the riser upside-down on an antistatic surface. Open the hinged plastic retainer that secures the rear-panel tab of the card. Pull evenly on both ends of the PCIe card to remove it from the socket on the PCIe riser. If the riser has no card, remove the blanking panel from the rear opening of the riser. Step 2 Install a new PCIe card: With the hinged tab retainer open, align the new PCIe card with the empty socket on the PCIe riser. PCIe riser 1/slot 1 has a long-card guide at the front end of the riser. Use the slot in the long-card guide to help support a full-length card. Push down evenly on both ends of the card until it is fully seated in the socket. Ensure that the card’s rear panel tab sits flat against the riser rear-panel opening and then close the hinged tab retainer over the card’s rear-panel tab. Figure 32.

Remove the top cover from the server as described in Removing the Server Top Cover. Step 2 Remove the existing mRAID riser: Using both hands, grasp the external blue handle on the rear of the riser and the blue finger-grip on the front end of the riser. Lift the riser straight up to disengage it from the motherboard socket. Set the riser upside down on an antistatic surface. Remove any card from the riser. Open the blue card-ejector lever that is on the edge of the card and then pull the card straight out from its socket on the riser. Step 3 Install a new mRAID riser: Install your card into the new riser. Close the card-ejector lever on the card to lock it into the riser. Connect cables to the installed card. Align the riser with the socket on the motherboard. At the same time, align the two slots on the back side of the bracket with the two pegs on the inner chassis wall.

Location of the mLOM Card Socket Below the mRAID Riser 1 Position of horizontal mLOM card socket 2 Position of mLOM card thumbscrew Replacing an mRAID Riser (Riser 3) The server has a dedicated internal riser that is used for either a Cisco modular storage controller card (RAID or HBA) or the SATA interposer card for embedded software RAID. This riser plugs into a dedicated motherboard socket and provides a horizontal socket for the installed card. This riser can be ordered as the following options: UCSC-XRAIDR-220M5—Replacement unit for this mRAID riser. UCSC-MRAID1GB-KIT—Kit for first-time addition of this riser (includes RAID controller, supercap, and supercap cable). See also Replacing a SAS Storage Controller Card (RAID or HBA) in Riser 3. See also Replacing the Supercap (RAID Backup). UCSC-SATA-KIT-M5—Kit for first-time addition of this riser (includes SATA interposer for embedded software RAID and SATA cables). See also Replacing a SATA Interposer Card. The NVMe-optimized, SFF 10-drive version, UCSC-220-M5SN, supports NVMe drives only and so does not use SAS or SATA RAID. This version of the server comes with an NVMe-switch card factory-installed in the internal mRAID riser to support NVMe drives in front-loading bays 3 - 10. The NVMe switch card is not orderable separately. Procedure Step 1 Prepare the server for component installation: Shut down and remove power from the server as described in Shutting Down and Removing Power From the Server.
