Installing and Removing a Blade Server
There are two types of blade server supported, half-width and full-width. Their installation is similar but with important differences. Refer to the documentation for the individual server models:
Installing and Removing a Blade Server Hard Drive
You can remove blade server hard drives without removing the blade server from the chassis. All other component replacement for a blade server requires removing the blade from the chassis. Unused hard drive bays should always be covered with cover plates (N20-BBLKD) to assure proper cooling and ventilation. The chassis is omitted from illustrations here to simplify the drawing.
Caution To prevent ESD damage, wear grounding wrist straps during these procedures and handle modules by the carrier edges only.
Installing a Blade Server Hard Drive
To install a blade server hard drive in either type of blade server, follow these steps:
Step 1 Place the hard drive lever into the open position by pushing the release button (see Figure 3-2).
Figure 3-2 Pressing the Button on the Front of the Hard Drive to Deploy the Lever (Cisco UCS B200 M1 shown)
Step 2 Gently slide the hard drive into the opening in the blade server until it seats into place.
Step 3 Push the hard drive lever into the closed position.
Figure 3-3 shows the positioning of a hard drive within a blade server.

Removing a Blade Server Hard Drive
To remove a hard drive from a blade server, follow these steps:
Step 1 Push the button to release the ejector, and then pull the hard drive from its slot.
Step 2 Place the hard drive on an antistatic mat or antistatic foam if you are not immediately reinstalling it in another blade server.
Step 3 Install a blank faceplate (N20-BBLKD) to keep dust out of the blade server if the slot will remain empty.
Installing and Removing Power Supplies
This section describes how to remove and install power supplies and includes the following topics:
Note The AC and DC power supplies are keyed to work only with the power distribution system in their respective chassis version. Mixing AC and DC in a given chassis is not supported.
Installing a Power Supply
To install a power supply (N20-PAC5-2500W or UCSB-PSU-2500DC48), follow these steps:
Step 1 Place the power supply's handle in the up position.
Step 2 Hold the power supply with both hands, and then slide it into the power supply bay,
Step 3 Press the handle down, and give the power supply a gentle push inward to ensure that the power supply is fully seated into the Power Distribution Unit (PDU).
Step 4 Tighten the captive screw.
Step 5 For an AC installation, plug the power cable into the corresponding 220 VAC-inlet connector on the PDU at the rear of the chassis. For a DC environment, see the "Connecting a DC Power Supply" section.
Note Depending on the outlet receptacle on your rack's power distribution unit, you may need the optional jumper power cord to connect the Cisco UCS 5108 server chassis to an outlet receptacle.
Step 6 Connect the other end of the power cable to the AC-power source.
Figure 3-4 Positioning a Power Supply in the Cisco UCS Server Chassis
Note Both grids in a power redundant system should have the same number of power supplies. If your system is configured for grid redundancy, slots 1 and 2 are assigned to grid 1 and slots 3 and 4 are assigned to grid 2. If there are only two power supplies in a redundant- mode chassis, they should be in slots 1 and 3. This would be a very unusual configuration, with a single B200 blade server in the chassis. A larger configuration would require two power supplies per grid. Slot and cord connection numbering is shown in Figure 3-5.

Removing a Power Supply
Caution If you are using the Cisco UCS 5108 server chassis with one power supply (this is only supported in earlier versions of the system software), removing the power supply will cause the servers and chassis to shut down. If you are using more than two power supplies, and you remove one of them, the servers continue to operate as long as the other power supplies are sufficient to meet the power requirements of the number of servers in the chassis.
To remove a power supply, follow these steps:
Step 1 Loosen the captive screw on the front of the power supply.
Step 2 Lift up the power supply's handle to unseat the power supply (see Figure 3-4).
Step 3 Using the lever, pull the power supply from its slot. Place your other hand under the power supply to support it while you slide it out of the chassis.
Step 4 Install a blank power supply filler panel (N20-CBLKP) if the power supply bay is to remain empty.
Installing and Removing a Power Distribution Unit (PDU)
Caution The Power Distribution Unit should only be replaced by a Cisco certified technician.This section is for reference only.
Caution You can not hot swap a PDU (N01-UAC1) (see Figure 3-9). The entire chassis will need to be shut down and all power cords should be unplugged before attempting this procedure.
Installing a PDU
To install a chassis PDU, follow these steps:
Step 1 Hold the PDU module from below, with the captive screws at the top of the module.
Figure 3-6 Positioning a PDU (N01-UAC1) in the Cisco UCS Server Chassis, AC version
Step 2 Push the PDU module into the chassis until it seats properly. If power supplies are installed, you may need to partially remove them.
Step 3 Tighten the captive screws.
Step 4 If necessary, reseat the power supplies and restart the system to observe LED behavior.
Removing a PDU
To remove a PDU module, follow these steps:
Step 1 Partially remove all installed power supplies. If a power supply is seated into the PDU, removal is difficult or impossible.
Step 2 Loosen the captive screws.
Step 3 Pull the PDU clear of the chassis by pulling on the captive screws. Support its weight from below.
Installing and Removing I/O Modules
The chassis contains I/O Modules (Cisco UCS 2104XP, UCS 2208XP, UCS 2204XP) that allow the blade servers in the chassis to communicate with Cisco UCS fabric interconnects. The chassis supports up to two I/O Modules, each with four or eight I/O ports.
Note A I/O module is sometimes referred to as an "I/OM."
This section includes the following topics:
I/OM Upgrade Considerations
Before you install a pair of UCS 2208XP I/O Modules to an existing UCS chassis using a pair of UCS 2104XPs, or add a new chassis with a pair of UCS 2208XP I/O Modules to a UCS instance you must perform a full upgrade to UCS software version 2.0(1) or later. The UCS 2208XP I/O Module is not recognized by earlier software releases.
Before you install a pair of UCS 2204XP I/O Modules to an existing UCS chassis using a pair of UCS 2104XPs, or add a new chassis with a pair of UCS 2204XP I/O Modules to a UCS instance you must perform a full upgrade to UCS software version 2.0(2) or later. The UCS 2204XP I/O Module is not recognized by earlier software releases.
Upgrading from a pair of UCS 2104XP to a pair of UCS 2200 series modules should be done first on the I/OM connected to the standby Fabric Interconnect, standby should be made active, then the I/OM connected to the new standby Fabric Interconnect can be upgraded.
If you are also performing an upgrade on the fabric interconnects, perform the upgrades separately. Attempting to upgrade both I/O modules ad fabric interconnects in a single process will likely complicate any reconfiguration needed on the FI ports.
Before you disconnect any data cables, make a record of which I/OM ports are connected to which Fabric interconnect ports.Use Table B-4 as appropriate. This will allow you to preserve the server pinning configuration your system uses.
Configurations of 1, 2, 4, or 8 10 GB connections between I/OM and Fabric interconnect are supported in UCS. If your UCS 2104XP has 4 physical connections and you want more, the next available upgrade step is the full 8 connections on the UCS 2208XP. You should verify that the I/O Module upgrade is completed with no problems before adding the connections for ports 5-8.
If you intend to implement the Fabric port channel feature available in UCS software version 2.0, you may need to rearrange the cabling between I/OM and Fabric Interconnect before performing the feature configuration. Fabric port channel will require that all physical links from a given I/OM physically connect to a contiguous block of ports (1-8 or 9-16, and so on). This feature requires a Cisco UCS M82-8P Virtual Interface Card in at least one blade server, and the UCS 2208XP I/O Module. See the Fabric Port Channel sections in the configuration guides for more details.
Removing an I/O Module
To remove a I/O Module of either the UCS 2100 or 2200 series, follow these steps:
Step 1 Remove all cables from the I/O Module.
Step 2 Loosen the captive screws on the I/O Module's levers.
Step 4 Using the levers, pull the I/O Module from its slot.
Step 5 Install a blank I/O Module filler panel (N20-CBLKI) if the I/O Module slot is to remain empty.
Note If you plan to remove a I/O module for an extended period of time, you must replace it with the N20-CBLKI blank to avoid EMI issues. Blanks can be order from Cisco Systems.

Figure 3-8 Positioning an 8 Port I/O Module within the Server Chassis
Installing an I/O Module
To physically install a single I/O Module, follow these steps:
Step 2 Slide the I/O Module into the I/O Module slot, ensuring that the I/O Module is fully seated.
Step 3 Close the levers and tighten the captive screw on each lever.
Step 4 Connect the networking cables (see the "SFP+ Transceivers" section and the "Proper I/O Module and Port Fabric Interconnect Connectivity" section).
Installing and Removing a Fan Module
You can hot swap a fan module (N20-FAN5) without causing an electrical hazard or damage to the system (see Figure 3-9). However, you can only remove one fan module while the system is operating. Removing more than one fan module could cause overheating.
Note When a fan is removed, louvers inside the chassis prevent recirculation of air into the system or loss of cooling. However, you should not leave the chassis for extended periods of time without all fan modules in place.
Installing a Fan Module
To install a fan module, follow these steps:
Step 1 Hold the fan module with the spring latch at the top of the module.
Step 2 Push the fan module into the chassis until it seats properly and the spring latch snaps into place.
Step 3 Listen for the fans if the chassis is powered on. You should immediately hear it operating. If you do not hear it, ensure that the fan module is inserted completely in the chassis and the faceplate is flush with the outside surface of the chassis.

Removing a Fan Module
To remove a fan module, follow these steps:
Step 1 Hold the fan module by its handle.
Step 2 Press down on the spring latch at the top of the fan module.
Step 3 Pull the fan module clear of the chassis.
Note The chassis is designed to have all fan modules in place and operating at all times. Do not leave a fan module bay empty for longer than is necessary to replace it with a new fan module.
