Cisco UCS B230 Blade Server Installation and Service Note

---

The Cisco UCS B230 Blade Server (shown in Figure 1) is one of the industry's highest-density two-socket blade server platforms, providing performance, density, and cost-effective value to data centers. With a half-width blade form factor, up to eight B230 servers can reside in the Cisco UCS 5100 Series Blade Server Chassis. Combining the performance of the Intel Xeon 6500 and 7500 series processors with up to 32 DIMM slots, the Cisco UCS B230 delivers compact performance and exceptional memory-per-core count to improve virtualization performance, reduce software license costs, and help enable more virtual machines. It has the following features:

•One or two Intel Xeon 6500 or 7500 series multi-core processors, for up to 16 processing cores

•32 DIMM slots for industry-standard double-data-rate 3 (DDR3) memory

•Two optional solid-state drives (SSDs)

•One dual-port adapter slot for up to 20 Gbps of I/O throughput

•Remote management through a Cisco Integrated Management Controller (CIMC) that implements a policy established in Cisco UCS Manager software

•Local keyboard, video, and mouse (KVM) access through a front console port on each server

•Out-of-band access by remote KVM, Secure Shell (SSH) Protocol, and virtual media (vMedia) and Intelligent Platform Management Interface (IPMI)

•A compact, high-performance, half-width blade server form factor

•LSI SAS 2008 RAID controller (onboard version of MegaRAID 9240)

M1 and M2 versions are available, supporting different processor classes. The Cisco UCS B230 is managed by Cisco UCS Manager version 1.4(1) and later. Cisco UCS Manager provisions Cisco UCS B-Series Blade Servers and their I/O properties using service profiles, which are infrastructure policies needed to provision servers and deploy applications, such as policies for power and cooling, security, identity, hardware health, and Ethernet and storage networking. Use of service profiles helps reduce the number of steps needed for provisioning, the opportunities for human error, and server and network deployment times. In addition, service profiles improve policy consistency and coherency across the entire Cisco Unified Computing System.

Every Cisco UCS B-Series Blade Server uses converged network adapters (CNAs) for access to the unified fabric. This design reduces the number of adapters, cables, and access-layer switches needed while still allowing traditional LAN and SAN connectivity, thus reducing capital expenditures and operating expenses. Among the I/O adapter options, and unique to the Cisco Unified Computing System, the Cisco UCS M81KR Virtual Interface Card (VIC) delivers up to 128 dynamic virtual adapters and interfaces, all integrated with Cisco UCS Manager and VMware vCenter Server. Incorporating Cisco VN-Link technology, this advanced fabric interface provides network visibility to virtual machines and helps enable configurations and policies to follow the virtual machine during migration.

1 Each server has a blank plastic tag that pulls out of the front panel, provided so you can add your own asset tracking label without interfering with the intended air flow.

Buttons

The Reset button is just inside the chassis and must be pressed using the tip of a paper clip or a similar item. Hold the button down for five seconds and then release it to restart the server if other methods of restarting are not working.

The beaconing function for an individual server can be turned on or off by pressing the combination button and LED or in UCS Manager. See Table 1 for details.

The power button and LED allows you to manually take a server temporarily out of service but leave it in a state where it can be restarted quickly. Pressing the button for one second initiates a graceful shutdown, and pressing it for over 4 seconds initiates an immediate shutdown. If the desired power state for a service profile associated with a blade server or an integrated rack-mount server is set to "off", using the power button or Cisco UCS Manager to reset the server will cause the desired power state of the server to become out of sync with the actual power state and the server may unexpected shutdown at a later time. To safely reboot a server from a power-down state, use the Boot Server action in Cisco UCS Manager.

Connectors

A console port is provided to give a direct connection to a blade server to allow operating system installation and other management tasks to be done directly rather than remotely. The port uses the KVM dongle device included in the chassis accessory kit.

The KVM cable (N20-BKVM, see Figure 2) provides a connection into a Cisco UCS blade server, providing a DB9 serial connector, a VGA connector for a monitor, and dual USB ports for a keyboard and mouse. With this cable you can create a direct connection to the operating system and the BIOS running on a blade server.

Figure 2 KVM Cable for Blade Servers

2	DB9 serial connector	4	2-port USB connector for a mouse and keyboard

LEDs

The LED indicators indicate whether the blade server is in active or standby mode, the status of the network link, the overall health of the blade server, and whether the server is set to give a flashing blue beaconing indication. See Table 1 for details.

The removable hard disks also have LEDs indicating hard disk access activity and hard disk health.

Installing and Removing a Solid State Drive

There are up to 2 front-accessible, hot-swappable SSD drives per blade. You can remove or install supported blade server SSD drives (see Table 2 ) without removing the blade server from the chassis. All other component replacements for a blade server require removing the blade from the chassis. Unused SSD drive bays should always be covered with cover plates (N20-BBLKD-7MM) to assure proper cooling and ventilation.

Table 2 Supported SSD Drives (M1 Models)

Product ID	Description
UCS-SSD100GI1F105	100 GB Low Height 7mm SATA SSD hot plug/drive sled mounted1
N20-D032SSD	32 GB Low Height SATA SSD SFF drive/hot plug/drive sled mounted
N20-D064SSD	64 GB Low Height SATA SSD SFF drive/hot plug/drive sled mounted

1 This SSD requires UCS capability catalog version 1.0.46 or later.

---

Caution To prevent ESD damage, wear grounding wrist straps during these procedures and handle modules by the carrier edges only.

---

Replacing an SSD with a drive of the same size, model, and manufacturer generally causes few problems with UCS Manager. If the drive being replaced was part of a RAID array we recommend using a newly ordered drive of identical size, model, and manufacturer to replace the failed drive. Cisco recommends following industry standard practice of using drives of the same capacity when creating RAID volumes. If drives of different capacities are used, the useable portion of the smallest drive will be used on all drives that make up the RAID volume. Before upgrading or adding an SSD to a running system, check the service profile in UCS Manager and make sure the new hardware configuration will be within the parameters allowed by the service profile.

Disk and RAID troubleshooting information is in the Troubleshooting Server Hardware chapter of the Cisco UCS Troubleshooting Guide. The B230 uses a built-in LSI SAS 2008 RAID controller (onboard version of the LSI MegaRAID 9240) .

Installing an SSD Drive

To install an SSD drive sled in a B230 blade server, follow these steps:

---

Step 1 Remove the blank faceplate, if necessary.

Step 2 With the drive label face up, align the drive with the desired drive bay and insert. (See Figure 1 to locate the bays; Figure 3 shows a drive removal which is largely the reverse process.)

Step 3 Slide the drive into the opening in the blade server until the catch is secured. You should feel the catch click into place.

Step 4 Give a gentle push to the rear to make sure the drive is fully seated.

Step 5 Check the LEDs on the blade server to make sure the drive is functioning as expected. (See Table 1.)

---

Removing an SSD Drive

To remove a drive from a blade server, follow these steps:

---

Step 1 Squeeze the catch mechanism to release the drive. (See Figure 3, callout 1.)

Step 2 Pull the drive from its slot. (See Figure 3, callout 2.)

Figure 3 Squeeze the Catch on the Drive Sled

Step 3 Place the drive on an antistatic mat or antistatic foam if you are not immediately reinstalling it in another blade server.

Step 4 Install a blank faceplate (N20-BBLKD-7MM) to keep dust out of the blade server if the slot will remain empty.

Removing and Installing a UCS B230

---

Caution To prevent ESD damage, wear grounding wrist straps while performing procedures where the server is removed from the chassis, and handle modules by the carrier edges only.

---

Before performing any internal operation on a blade server, you must remove it from the chassis. This section describes the following topics:

•Removing a Cisco UCS B230 Blade Server

•Installing a Cisco UCS B230 Blade Server

Shutting Down and Powering Off a Blade Server

The server has two power modes:

•Main power mode—Power is supplied to all server components and any supported operating system.

•Standby power mode—Power is supplied only to the service processor and the cooling fans and it is safe to remove the server for service.

After establishing a connection to the blade server's operating system, you can directly shut down the blade server using the operating system.

You can invoke a graceful shutdown or an emergency shutdown (hard shutdown) by using either of the following methods:

•UCS Manager, see either the Cisco UCS Manager GUI configuration guide or the Cisco UCS Manager CLI configuration guide.

•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.

•Green indicates that the server is in main power mode and must be shut down before it can be safely removed. Go to Step 2.

•Amber indicates that the server is already in standby mode and can be safely removed. 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 If you are shutting down an entire chassis, you should now disconnect the power cords from the chassis to completely power off the servers. If you are only shutting down one server, you do not need to unplug the chassis and may simply to removing the server.

---

Removing a Cisco UCS B230 Blade Server

To remove a blade server from the chassis, follow these steps:

---

Step 1 Loosen the captive screw on the front of the blade.

Step 2 Remove the blade from the chassis by pulling the ejector lever on the blade until it unseats the blade server.

Step 3 Slide the blade part of the way out of the chassis, and place your other hand under the blade to support its weight.

Step 4 Once removed, place the blade on an antistatic mat or antistatic foam if you are not immediately reinstalling it into another slot.

Step 5 If the slot is to remain empty, install a blank faceplate (N20-CBLKB1) to keep dust out of the chassis.

---

Installing a Cisco UCS B230 Blade Server

To install a blade server, follow these steps:

---

Step 1 Grasp the front of the blade server and place your other hand under the blade to support it.

Step 2 Open the ejector lever in the front of the blade server. (See Figure 4.)

Figure 4 Inserting a Blade Server in the Chassis

Step 3 Gently slide the server into the opening until you cannot push it any farther. At a certain point it will engage the ejector lever.

Step 4 Press the ejector lever as it catches the edge of the chassis and presses the blade server all the way in. Give a gentle push to the rear to be sure the server is fully seated into the midplane.

Step 5 Tighten the captive screw on the front of the blade to no more than 3 in-lbs. Tightening with bare fingers only is unlikely to lead to stripped or damaged captive screws.

---

Removing a Blade Server Cover

---

Caution To prevent ESD damage, wear grounding wrist straps while performing procedures where the cover is removed from the server, and handle modules by the carrier edges only.

---

To open the blade server, follow these steps:

---

Step 1 Set the ejector lever to the angle shown in Figure 5.

Figure 5 Opening a Cisco UCS B230 Blade Server

Step 2 Remove any installed SSDs. If needed, refer to "Removing an SSD Drive."

Step 3 Press and hold the button down as shown in Figure 5.

Step 4 While holding the back end of the cover, pull the cover forward and up.

---

Note The front face of the server is attached to the top cover and will come off with the cover.

---

---

Tip Replacement of the cover is the reverse of the removal procedure. Be sure to re-install the SSDs after the cover is secured.

---

Blade Server Internal Components

Figure 6 calls out the various components within the blade server.

Figure 6 Inside View of a Blade Server

1	DIMM slots	2	CPU 1 and heat sink
3	CPU 2 and heat sink	4	DIMM slots
5	Adapter card connector	6	Diagnostic button

Diagnostics Button and LEDs

At blade start-up, POST diagnostics test the CPUs, DIMMs, and adapter cards, and any failure notifications are sent to Cisco UCS Manager. You can view these notifications in the System Error Log or in the output of the show tech-support command. If errors are found, an amber diagnostic LED also lights up next to the failed component. During run time, the blade BIOS, component drivers, and OS all monitor for hardware faults and will light up the amber diagnostic LED for a component if an uncorrectable error or correctable errors (such as a host ECC error) over the allowed threshold occur.

Diagnostic LED states are saved and if you remove the blade from the chassis the LED values persist for up to 10 minutes. Pressing the LED diagnostics button on the motherboard causes the LEDs that currently show a component fault to light for up to 30 seconds for easier component identification. LED fault values are reset when the blade is reinserted into the chassis and booted, and the process begins from its start.

If DIMM insertion errors are detected, they may cause the blade discovery to fail and errors are reported in the server POST information, viewable using the UCS Manager GUI or CLI. UCS blade servers require specific rules to be followed when populating DIMMs in a blade server, and the rules depend on the blade server model.

Drive status LEDs are on the front face of the server. Faults on the CPU, DIMMs, or adapter cards also cause the server health LED to light solid Amber for minor error conditions or blinking Amber for critical error conditions.

Working Inside the Blade Server

This section describes how to perform the following tasks within a blade server:

•Removing a CPU or Heat Sink

•Installing a CPU or Heat Sink

•Installing a Motherboard CMOS Battery

•Installing an Adapter Card

•Installing Memory

Removing a CPU or Heat Sink

You can order your blade server with two CPUs, or upgrade later to a second CPU. Both CPUs must be of the same type, and memory in slots intended for the second CPU is not recognized if the second CPU is not present. You may need to use these procedures to move a CPU from one server to another, or to replace a faulty CPU.

Table 3 and Table 4 list the available CPU options:

To remove a CPU or heat sink, follow these steps:

---

Step 1 Unscrew the two captive screws securing the heat sink to the motherboard. (See Figure 7, callout 1.)

Step 2 Remove the heat sink (N20-BHTS6). (See Figure 7, callout 2.) Remove the old thermal compound from the bottom of the heat sink using the cleaning kit (UCSX-HSCK= ) available from Cisco. Follow the instructions on the two bottles of cleaning solvent.

Step 3 Unhook the socket latch. (See Figure 7, callout 3.)

Step 4 Open the socket latch. (See Figure 7, callout 4.)

Step 5 Remove the CPU or socket protective cover. (See Figure 7, callout 5.)

Figure 7 Removing the Heat Sink and Accessing the CPU Socket

---

In systems shipped with one CPU, the vacant CPU has an N20-BBFLA-230 air blocker (see Figure 8) in place of the CPU heat sink. The blocker is needed for cooling air to flow as designed and needed through the server, and should be kept in place unless another CPU is added. If you are downgrading to a single CPU, order the air blocker and install it in the empty CPU location.

Figure 8 Air Blocker (shown in CPU 2)

Installing a CPU or Heat Sink

To install a CPU or heat sink, follow these steps:

---

Step 1 Place the CPU on the base with the notches aligned to the pins on the base. (See Figure 9, callout 1.)

Figure 9 Inserting the CPU and Replacing the Heat Sink

Step 2 Close the socket latch. (See Figure 9, callout 2.)

Step 3 Lock the socket latch into place with the hook. (See Figure 9, callout 3.)

Step 4 Attach the thermal pad (also available as a spare A04-BTHP3=) provided with the replacement CPU or server to the bottom of the heat sink, then remove the covering film from the side that will adhere to the CPU. (See Figure 9, callout 4.)

Step 5 Replace the heat sink (N20-BHTS6). (See Figure 9, callout 5.)

---

Caution Make sure that the heat sink fins are aligned to run along the length of the blade server (see Figure 9).

---

Step 6 Secure the heat sink to the motherboard by tightening the two captive screws hand tight. (See Figure 9, callout 6.)

Cisco does not support third-party memory DIMMs, and in some cases their use may irreparably damage the server and require an RMA and down time.

Memory Arrangement

The UCS B230 contains 32 slots for installing DIMMs. Each CPU has 16 DIMM slots organized in pairs. This blade server needs at least one matched pair of DIMMs attached to CPU 1 or CPU 2. Both CPUs can boot and run from a single DIMM pair. DIMM pairs must be identical (the same size, speed, and manufacturer) and are sold in appropriately matched pairs, but one DIMM pair on a CPU can be different from other pairs. DIMMs installed in slots for an absent CPU are not recognized. You should also install memory evenly across the installed CPUs, though it is not a requirement. DIMM slots are color coded blue, white, yellow, and black, and we recommend that you install memory in that order. Each channel pair is identified by a letter: A, B, C, or D for each CPU. Each DIMM pair member is identified by numbers, 0, 1, 2 or 3. You must install additional DIMMs as shown in Table 8.

Table 8 DIMM Installation Order

DIMMs per CPU	Numbered slots 1
2 (Blue)	(B0, B1)
4 (Blue)	(B0, B1) - (D0, D1)
8 (Blue, White)	(B0, B1) - (D0, D1) - (A0, A1) - (C0, C1)
16 (Blue, white, yellow, black)	(B0, B1) - (D0, D1) - (A0, A1) - (C0, C1) - (B2, B3) - (D2, D3) - (A2, A3) - (C2, C3)

1 The slots inside the brackets are electrically paired with each other, and should be populated with identical matched DIMMs that were ordered as a pair. Do not swap a paired DIMM with a DIMM that is not identical in manufacturer part number.

Figure 13 shows how DIMMs slots are laid out on the blade server. A CPU uses the DIMM slots directly to the right or the left of the CPU. Note that the arrangement for CPU 2 and CPU 1 is not identical.

Memory Performance

When configuring your server, consider the following.

•DIMMs within the blade server can be of a different size.

•Your selected CPU(s) can have some effect on performance. If two CPUs are used, both must be of the same type.

Bandwidth and Performance

You can achieve maximum bandwidth, performance, and system memory using the following configuration:

•16 DIMM per CPU (32 DIMMs total)

•Maximum capacity of 256 GB (using 8 GB DIMMs)

Performance Loss

Performance is less than optimal if the following memory configurations are used:

•Mixing DIMM sizes and densities within a pair is not allowed and both DIMMs in the pair will be removed from the memory array

•Unevenly populating DIMMs between CPUs

Depending on the application needed, performance loss might or might not be noticeable or measurable. Partially populating a pair is unsupported and will not work at all.

Server Troubleshooting

For general server troubleshooting information, refer to the "Troubleshooting Server Hardware" chapter of the Cisco UCS Troubleshooting Guide.

Server Configuration

UCS servers are intended to be configured and managed using UCS Manager. Refer to the UCS Manager Configuration Guide appropriate for your UCS Manager version
