Preparing for Server Component Installation
This section describes how to prepare for component installation, and it includes the following topics:
•Required Equipment, page 3-8
•Shutting Down and Powering Off the Server, page 3-8
•Removing and Replacing the Server Top Cover, page 3-9
•Serial Number Location, page 3-10
•Hot-Swap or Hot-Plug Replacement, page 3-10
Required Equipment
The following equipment is used to perform the procedures in this chapter:
•Number 2 Phillips-head screwdriver
•Electrostatic discharge (ESD) strap or other grounding equipment such as a grounded mat
Shutting Down and Powering Off the Server
The server can run in two power modes:
•Main power mode—Power is supplied to all server components and any operating system on your
drives can run.
•Standby power mode—Power is supplied only to the service processor and the cooling fans and it
is safe to power off the server from this mode.
You can invoke a graceful shutdown or a hard shutdown by using either of the following methods:
•Use the Cisco IMC management interface.
•Use the Power button on the server front panel. To use the Power button, follow these steps:
Step 1 Check the color of the Power Status LED (see the “Front Panel LEDs” section on page 3-2).
•Green—The server is in main power mode and must be shut down before it can be safely powered
off. Go to Step 2.
•Amber—The server is already in standby mode and can be safely powered off. Go to Step 3.
Step 2 Invoke either a graceful shutdown or a hard shutdown:
Caution To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown
of the operating system.
•Graceful shutdown—Press and release the Power button. The operating system performs a graceful
shutdown and the server goes to standby mode, which is indicated by an amber Power Status LED.
•Emergency shutdown—Press and hold the Power button for 4 seconds to force the main power off
and immediately enter standby mode.
Step 3 Disconnect the power cords from the power supplies in your server to completely power off the server.

Preparing for Server Component Installation
Removing and Replacing the Server Top Cover
Step 1 Remove the top cover (see Figure 3-4).
a. If the cover latch is locked, use a screwdriver to turn the lock 90-degrees counterclockwise to unlock
it. See Figure 3-4.
b. Lift on the end of the latch that has the green finger grip. The cover is pushed back to the open
position as you lift the latch.
c. Lift the top cover straight up from the server and set it aside.
Step 2 Replace the top cover:
Note The latch must be in the fully open position when you set the cover back in place, which allows
the opening in the latch to sit over a peg that is on the fan tray.
a. With the latch in the fully open position, place the cover on top of the server about one-half inch
(1.27 cm) behind the lip of the front cover panel. The opening in the latch should fit over the peg
that sticks up from the fan tray.
b. Press the cover latch down to the closed position. The cover is pushed forward to the closed position
as you push down the latch.
c. If desired, lock the latch by using a screwdriver to turn the lock 90-degrees clockwise.

Installing or Replacing Server Components
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Statement 1029
Caution When handling server components, wear an ESD strap to avoid damage.
Tip You can press the unit identification button on the front panel or rear panel to turn on a flashing unit
identification LED on the front and rear panels of the server. This button allows you to locate the specific
server that you are servicing when you go to the opposite side of the rack. You can also activate these
LEDs remotely by using the Cisco IMC interface. See the “Status LEDs and Buttons” section on
page 3-2 for locations of these LEDs.

Replacing SAS/SATA Hard Drives or Solid State Drives
This section includes the following information:
•SAS/SATA Drive Population Guidelines, page 3-13
•Replacing a SAS/SATA Drive, page 3-15
SAS/SATA Drive Population Guidelines
The server has two different drive backplane options:
•The small form factor (SFF), 8-drives version can hold up to eight 2.5-inch SAS/SATA hard drives
or solid state drives. SAS/SATA drives are hot-swappable.
•The large form factor (LFF), 4-drives version can hold up to four 3.5-inch SAS/SATA hard drives.
The drive-bay numbering is shown in Figure 3-6.
Figure 3-6 Drive Numbering, SFF Drives, Eight-Drive Version
Figure 3-7 Drive Numbering, LFF Drives, Four-Drive Version
Observe these drive population guidelines for optimum performance:
•When populating drives, add drives to the lowest-numbered bays first.
•Keep an empty drive blanking tray in any unused bays to ensure proper airflow.
•You can mix SAS/SATA hard drives and SAS/SATA SSDs in the same server (the LFF version of
the server does not support SSDs). However, you cannot configure a logical volume (virtual drive)
that contains a mix of hard drives and SSDs. That is, when you create a logical volume, it must
contain all SAS/SATA hard drives or all SAS/SATA SSDs.
4K Sector Format Drives Considerations
•You must boot 4K sector format drives in UEFI mode, not legacy mode. See Setting Up Booting in
UEFI Mode in the BIOS Setup Utility, page 3-14 or Setting Up Booting in UEFI Mode in the Cisco
IMC GUI, page 3-14.
•Do not configure 4K sector format and 512-byte sector format drives as part of the same RAID
volume.
•Operating system support on 4K sector drives is as follows: Windows: Win2012 and Win2012R2;
Linux: RHEL 6.5, 6.6, 6.7, 7.0, 7.2; SLES 11 SP3, and SLES 12. ESXi/Vmware is not supported.

Replacing a 2.5-Inch Form-Factor NVMe PCIe Solid State Drive
This section is for replacing 2.5-inch small form-factor (SFF) NVMe PCIe SSDs in front-panel drive
bays. To replace HHHL form-factor NVMe PCIe SSDs in the PCIe slots, see Replacing HHHL Form
Factor NVME Solid State Drives, page 3-21.

•Replacing a 2.5-inch Form-Factor NVMe PCIe SSD, page 3-18
•Installing PCIe Riser Version 2B For NVMe SFF 2.5-Inch SSDs, page 3-19
2.5-Inch Form-Factor NVMe PCIe SSD Population Guidelines
The SFF 8-drive version of the server supports up to two NVMe SFF 2.5-inch SSDs in drive bays 1 and
2 only.
2.5-inch Form-Factor NVME PCIe SSD Requirements and Restrictions
Observe these requirements for NVMe SFF 2.5-inch SSDs:
•Only the SFF, 8-drives version of the server supports NVMe SFF 2.5-inch SSDs.
•The server must have two CPUs. PCIe riser 2 is not available in a single-CPU system (the PCIe riser
carries the PCIe signal from the front panel drive bays).
•PCIe riser version 2B (UCSC-PCI-2B-220M4), with bundled cables. This version of the riser has
cable connectors for the PCIe cables that connect to the drive backplane.
Observe these restrictions for NVMe SFF 2.5-inch SSDs:
•You can boot (UEFI only) from an NVMe SFF 2.5-inch SSD only with Cisco IMC 2.0(13) or later
server firmware. For Cisco UCS Manager-integrated servers, booting is supported only with Cisco
UCS Manager 3.1(2) or later software.
•NVMe SFF 2.5-inch SSDs support booting only in UEFI mode. Legacy boot is not supported.
•You cannot control NVMe PCIe SSDs with a SAS RAID controller because they communicate with
the server via the PCIe bus.
•You can combine NVMe SFF 2.5-inch SSDs and HHHL form-factor SSDs in the same system, but
the same partner brand must be used. For example, two Intel NVMe SFF 2.5-inch SSDs and two
HHHL form-factor HGST SSDs is an invalid configuration. A valid configuration is two HGST
NVMe SFF 2.5-inch SSDs and two HGST HHHL form-factor SSDs.
•UEFI boot is supported in the five operating systems listed in Table 3-4, when your server is running
Cisco IMC 2.0(13) or later firmware. Refer to this table for OS-informed hot-insertion and
hot-removal support by operating system:

Enabling Hot-Plug Support in the System BIOS
In Cisco IMC 2.0(13) and later, hot-plug (OS-informed hot-insertion and hot-removal) is disabled in the
system BIOS by default.
•If the system was ordered with NVMe PCIe SSDs, the setting was enabled at the factory. No action
is required.
•If you are adding NVMe PCIe SSDs after-factory, you must enable hot-plug support. See the
following procedures.
Enabling Hot-Plug Support in the BIOS Setup Utility
Step 1 Enter the BIOS setup utility by pressing the F2 key when prompted during bootup.
Step 2 Locate the setting: Advanced > PCI Subsystem Settings > NVMe SSD Hot-Plug Support.
Step 3 Set the value to Enabled.

Replacing a 2.5-inch Form-Factor NVMe PCIe SSD
Note OS-surprise removal is not supported. OS-informed hot-insertion and hot-removal are supported only
with Cisco IMC release 2.0(13) and later and they depend on your OS version. See Table 3-4 for support
by OS.
Note OS-informed hot-insertion and hot-removal must be enabled in the system BIOS. See Enabling Hot-Plug
Support in the System BIOS, page 3-17.
For information about drive tray LEDs, see Front Panel LEDs, page 3-2.
Step 1 Remove an existing NVMe SFF 2.5-inch SSD:
a. Shut down the NVMe SFF 2.5-inch SSD to initiate an OS-informed removal. Use your operating
system interface to shut down the drive, and then observe the drive-tray LED:
– Green—The drive is in use and functioning properly. Do not remove.
– Green, blinking—the driver is unloading following a shutdown command. Do not remove.
– Off—The drive is not in use and can be safely removed.
b. Press the release button on the face of the drive tray. See Figure 3-8.
c. Grasp and open the ejector lever and then pull the drive tray out of the slot.
d. If you are replacing an existing SSD, remove the four drive tray screws that secure the SSD to the
tray and then lift the SSD out of the tray.
Note If this is the first time that NVMe SFF 2.5-inch SSDs are being installed in the server, you must install
PCIe riser version 2B and connect its cables before installing the drive. See Installing PCIe Riser Version
2B For NVMe SFF 2.5-Inch SSDs, page 3-19.
Step 2 Install a new NVMe SFF 2.5-inch SSD:
a. Place a new SSD in the empty drive tray and replace the four drive tray screws.
b. With the ejector lever on the drive tray open, insert the drive tray into the empty drive bay.
c. Push the tray into the slot until it touches the backplane, and then close the ejector lever to lock the
drive in place.
Step 3 Observe the drive-tray LED and wait until it returns to solid green before accessing the drive:
•Off—The drive is not in use.
•Green, blinking—the driver is initializing following hot-plug insertion.
•Green—The drive is in use and functioning properly.

Installing or Replacing Server Components
Installing PCIe Riser Version 2B For NVMe SFF 2.5-Inch SSDs
PCIe Riser Version 2B (UCSC-PCI-2B-220M4) has two cable connectors that are used to provide
communication from the front-panel drive bays to the PCIe bus.
Figure 3-9 PCIe Riser Assembly UCSC-PCI-2B-C220M4
Step 1 Remove an existing PCIe riser assembly that you are replacing:
a. Power off the server as described in Shutting Down and Powering Off the Server, page 3-8.
b. 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.
c. Remove the top cover as described in Removing and Replacing the Server Top Cover, page 3-9.
d. Use two hands to grasp the metal bracket of the riser assembly and lift straight up to disengage its
connectors from the two sockets on the motherboard.
e. If the riser has any cards installed, remove them from the riser.
Step 2 Install a new PCIe riser assembly Version 2B:
a. If you removed any cards from the old riser assembly, install the cards to the new riser assembly (see
Replacing a PCIe Card, page 3-50).
b. Position the riser assembly over its two sockets on the motherboard and over the chassis alignment
channels (see Figure 3-27):
c. Carefully push down on both ends of the riser assembly to fully engage its connectors with the two
sockets on the motherboard.
Step 3 Connect the two cables that come with UCSC-PCI-2B-220M4:
a. Connect both cable connectors to the two connectors on the riser 2B (see Figure 3-10).
b. Route the cables to the front of the server using the recommended path through the chassis cable
guides as shown in Figure 3-10.

c. Connect the two ends of the cable to the PCIe connectors on the drive backplane.
Connect the cable labeled Port A to the Port A connector; connect the cable labeled Port B to the
Port B connector (see Figure 3-10).
Step 4 Replace the top cover.
Step 5 Replace the server in the rack, replace cables, and then power on the server by pressing the Power button.
