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 may be turned on or off by pressing the combination button and LED.

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. 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) shown in Figure 2 allows a KVM onnection 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. The pinout for the DB-9 connector is shown in Table 2.

Installing and Removing a Blade Server Hard Drive

There are up to 4 front-accessible, hot-swappable, 2.5-inch SAS or SATA drives per blade. 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.

Replacing an HDD or 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 HDD 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.

Hard disk and RAID troubleshooting information is in the Troubleshooting Server Hardware chapter of the Cisco UCS Troubleshooting Guide. The B440 uses an LSI SAS 2108 RAID controller (the onboard version of the LSI MegaRAID 9260).

Table 3 shows the drives supported in this 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. (See Figure 3.)

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.


Figure 3 Removing and Installing a Hard Drive

Installing a Blade Server Hard Drive

To install a blade server hard drive, follow these steps:


Step 1 Place the hard drive lever into the open position by pushing the release button (see Figure 3).

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.


You can use UCS Manager to format and configure RAID services. refer to the UCS Manager configuration guide for your software release for details on RAID configuration.

If you need to move a RAID cluster, refer to the Moving a RAID Cluster section of the the Troubleshooting Server Hardware chapter of the Cisco UCS Troubleshooting Guide.

Removing and Installing a UCS B440 High Performance Blade Server

Before performing any internal operation on a blade server, you must turn it off and remove it from the chassis.


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

Shutting Down and Powering Off A Blade 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 hard 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.

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:

Use the UCS Manager . See either the Cisco UCS Manager GUI Configuration Guide or the Cisco UCS Ma nager 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 powered off. Go to Step 2.

Amber indicates that 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 will perform 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 all blade servers in a 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 can skip unplugging the chassis and move to removing the server.


Removing a Cisco UCS B440 High Performance Blade Server

Using UCS Manager, decommission the server using UCS Manager before physically removing the server. To remove a blade server from the chassis, follow these steps:


Step 1 Turn off the blade server using either UCS Manager or the power on standby button.

Step 2 Completely loosen the captive screws on the front of the blade.

Step 3 Remove the blade from the chassis by pulling the ejector levers on the blade until it unseats the blade server.

Step 4 Slide the blade part of the way out of the chassis, and place your other hand under the blade to support its weight.

Step 5 Once removed, place the blade on an antistatic mat or antistatic foam if you are not immediately reinstalling it into another slot.

Step 6 If the slot is to remain empty, reinstall the slot divider (N20-CDIVV) and install two blank faceplates (N20-CBLKB1) to keep assure proper ventilation and cooling.


Installing a Cisco UCS B440 High Performance Blade Server

While the blades and chassis are designed for any device to operate in any slot, the following placement guidelines should be used when installing blades to distribute weight as intended and make insertion and removal easier:

1. 1. A chassis filled with half-width servers will require slot dividers be installed. A chassis filled with full-width servers will require the removal of all slot dividers.

2. 2. If a mixture of full- and half-width servers is desired, place full-width blades in slot 1 and down, and place half-width blades in slot 8 and up. Slot dividers are required between half-width servers to provide support to the bays above.

To install a blade server, follow these steps:


Step 1 If necessary, remove the slot divider (N20-CDIVV) from the chassis. To do this, follow these steps:

a. Simultaneously pull up on the left side catch and push down on the right side catch as shown in callout 1 of Figure 4.

b. Pull the slot divider out of the chassis as shown in callout 2 of Figure 4. Keep the slot divider in case it is needed at another time.


Tip To reinstall the slot divider, align it with the dimples in the slot top and bottom and slide it back in until it clicks into place.


Figure 4 Removing a Chassis Partition

Step 2 Grasp the front of the blade server and place your other hand under the blade to support it. See Figure 5.

Figure 5 Positioning a Blade Server in the Chassis

Step 3 Open the ejector levers in the front of the blade server.

Step 4 Gently slide the blade into the opening until you cannot push it any farther.

Step 5 Press the ejector levers so that they catch the edge of the chassis and press the blade server all the way in.

Step 6 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

To open a blade server, follow these steps:


Step 1 Press and hold the button down as shown in callout 1 of Figure 6.

Step 2 While holding the back end of the cover, pull the cover back and upas shown in callout 2 of Figure 6.

Diagnostics Button and LEDs

At blade start-up, POST diagnostics test the CPUs, DIMMs, HDDs and adapter cards, and any failure notifications are sent to UCSM. You can view these notification in the System Error Log or in the output of the show tech-support command. If errors are found, an amber diagnostic LED will also light 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.

LED states are saved, and if you remove the blade from the chassis the LED values will persist for up to 10 minutes. Pressing the LED diagnostics button on the motherboard will cause 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 will be 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. Refer to the documentation for a specific blade server for those rules.

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

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


Step 1 Unscrew the four captive screws securing the heat sink to the motherboard as shown in callout 1 of Figure 9.

Step 2 Remove the heat sink (N20-BHTS3) as shown in callout 2 of Figure 9. 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 as shown in callout 3 of Figure 9.

Step 4 Open the socket latch as shown in callout 4 of Figure 9.

Step 5 Remove the CPU or socket protective cover as shown in callout 5 of Figure 9.

Figure 9 Removing the Heat Sink and Accessing the CPU Socket

If a replacement CPU will not be used and the CPU will be left vacant, you should have an air blocker installed rather than a heat sink. The air blocker assures that air flows where it is needed, and is shown in Figure 10.

Figure 10 CPU Air Blocker


Installing a CPU or Heat Sink

Before installing a new CPU in a server, verify the following:

The CPU is supported for that model server.

A BIOS is available that supports the CPU/DIMM and server combination.

The service profile for this server in UCS Manager will recognize and allow the new CPU. This is especially important if you have been using a single processor and install a second processor.

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 11, callout 1.

Figure 11 Inserting the CPU and Replacing the Heat Sink

Step 2 Close the socket latch. See Figure 11, callout 2.

Step 3 Lock the socket latch into place with the hook. See Figure 11, 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.

Step 5 Replace the heat sink. See Figure 11, callout 5.

Step 6 Secure the heat sink to the motherboard by tightening the two captive screws hand tight. See Figure 11, callout 6.


Caution Make sure that the heat sink fins are aligned to run along the length of the blade server (see Figure 11).


Installing Memory

Check the server's service profile setting in UCS Manager before adding memory to make sure that the new memory will be recognized. To install a DIMM into the blade server, follow these steps:


Step 1 Open both DIMM connector latches, refer to callout 1 in Figure 12.

Figure 12 Installing DIMMs in the Blade Server

Step 2 Press the DIMM into its slot evenly on both ends until it clicks into place, refer to callout 2 in Figure 12. The DIMM connector latches will snap into place.


Note DIMMs are keyed and will only insert into their slot if the notch at the bottom of the DIMM is oriented correctly. Attempting to force an incorrectly oriented DIMM will damage the slot.


Step 3 Press the DIMM connector latches inward slightly to seat them fully. Refer to callout 3 in Figure 12.


Memory and Performance

This section describes the type of memory that the blade server requires, and its effect on performance. The following topics are covered:

Supported DIMMs

Memory Arrangement

Memory Performance

Related Documentation

Modern processors are designed to support several generations of memory technology. Cisco's Extended Memory Technology allows us to replace high-density DIMMs with multiple lower-density DIMMs in a way that is transparent to the processor and to applications. In some configurations, we are emulating DIMMs that are not available, such as making four 8-GB DIMMs appear to be a single 32-GB DIMM. In other cases we can emulate high cost-per-bit DIMMs with multiple low cost-per-bit DIMMs; for example, making four 4 GB DIMMs emulate a 16 GB DIMM.

Caution Server memory is always sold as a matched DIMM pair intended to be installed together in a single UCS Server memory bank. Un-pairing this set and mixing with other non-matched DIMMs can potentially result in memory errors.

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 Cisco UCS B440 high-performance blade server contains 32 slots for installing DIMMs—8 for each CPU. Each CPU has 8 DIMM slots and DDR channels, with 4 pairs of DIMMs operating in lockstep (see Figure 13) so you must install additional DIMMs in pairs, as laid out in Table 8. This blade server needs at least one matched pair of DIMMs attached to CPU 1 or CPU 2. All four CPUs can boot and run from a single DIMM pair. DIMM pairs must be identical, but one DIMM pair on a CPU can be different from other pairs. DIMMs installed in slots for an absent CPU will not be recognized. For optimal performance, distribute DIMMs evenly across all CPUs. DIMM connector latches are color coded blue, yellow, black, and white, and Cisco recommends installing memory in that order. It is also recommended to install memory evenly across the installed CPUs.

DIMMs for CPU 4


Channels

Each CPU has 8 channels, consisting of 4 matched pairs. Each channel pair is identified by a letter: A, B, C, or D for each CPU. Each channel pair member is identified by numbers, either 1 or 0.

Figure 14 shows how channels are physically laid out on the blade server. The DIMM slots are to the left of their associated CPU. When installing DIMMs, you must add them in pairs in the configurations shown in Table 8:

Table 8 Adding DIMMs to a CPU

# of DIMMs to Install
Install DIMMs in Slot #

2 (blue)

(A0, A1)

4 (blue, white )

(A0, A1)-(C0, C1)

8 (blue, white, yellow, and black)

(A0, A1)-(C0, C1)-(B0, B1)-( D0, D1)



Note This server does not support odd numbers of DIMMs in a channel, or a configuration of 6 DIMMs per CPU. These are the only three supported DIMM configurations. The DIMMs are sold in matched pairs which must be installed in the pairs shown in Table 8. Mixing pairs , even otherwise identical sets, within a CPU will lead to memory errors.

Figure 15 shows a logical view of the channels.

DIMMs can be used in the High-performance blade server using the slot pairs described in Table 8.

Memory Performance

When configuring your server, consider the following.

DIMMs within the blade server can be of a different size, but mixing speeds will cause the faster DIMMs to run at the speed of the slower DIMMs.

Your selected CPU(s) can have some affect 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:

DDR3, 1066 millions of transfers per second (MT/s) across three Channels

8 DIMM per CPU (32 DIMMs)

Maximum capacity of 256 GB (using 8 GB DIMMs)


Note The memory available for this server can only run at 1066 MHz.


Performance Loss

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

Mixing DIMM sizes and densities within a pair

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.

Installing an Adapter Card

The network adapters and interface cards all have a shared installation process. The following options are available:

2 Requires UCS Manager 2.0(2) or later.


If you are switching from one type of card to another, before you physically perform the switch make sure you have downloaded the latest device drivers and loaded them into the server's OS. For the most recent details, refer to the firmware management chapter of one of the UCS Manager software configuration guides.

Adapter cards can be installed in either slot 1 or slot 0; they can be of the same type or as of UCS Manager 1.3(1), the following mixed configurations are supported:

M81KR with M71KR-E/Q

M81KR with M72KR-E/Q

To install an adapter card on the blade server, follow these steps:


Step 1 Position the adapter board connector above either mother board connector and align the three adapter captive screws to the posts on the motherboard as shown in callout 1 of Figure 16.

Step 2 Firmly press the adapter connector into the motherboard connector as shown in callout 2 of Figure 16. If the seating is bad, it may cause the network connection LED to stay amber when the server is restarted.

Step 3 Tighten the three captive screws identified in callout 3 of Figure 16.

Installing a RAID License Key

Depending on the RAID license key that is installed, the onboard RAID controller supports the following RAID levels:

RAID 0 (data striping): Data is striped across all disks in the array, providing fast throughput. There is no data redundancy, and all data is lost if any disk fails.

RAID 1 (disk mirroring): Data is written to two disks, providing complete data redundancy if one disk fails. The maximum array size is equal to the available space on the smaller of the two drives.

RAID 5 (disk striping with distributed parity): Data is striped across all disks in the array. Part of the capacity of each disk stores parity information that can be used to reconstruct data if a disk fails. RAID 5 provides good data throughput for applications with high read request rates.

RAID 6 (disk striping with distributed parity across two disks): Data is striped across all disks in the array and two parity disks are used to provide protection against the failure of up to two physical disks. In each row of data blocks, two sets of parity data are stored.

RAID 10 (RAID 1 and RAID 0 in spanned arrays): RAID 10 uses mirrored pairs of disks to provide complete data redundancy and high throughput rates.

RAID 50 (RAID 5 and RAID 0 in spanned arrays): RAID 50 uses both parity and disk striping across multiple disks to provide complete data redundancy and high throughput rates.

RAID 60 (RAID 6 and RAID 0 in spanned arrays): RAID 60 uses both distributed parity across two parity disks and disk striping across multiple disks to provide complete data redundancy and high fault tolerance.

The Cisco RAID key is OEM version of LSI MegaRAID SAS 8880EM2 SGL. If a replacement is needed, the stock LSI version will not work as a replacement as the physical connector is different, you must order replacements from Cisco.

User information for RAID controllers is in the Cisco UCS Servers RAID Guide.

To install a RAID license key, follow these steps:


Step 1 With the cover removed, locate the RAID controller daughter card. It is directly behind the BBU.

Step 2 Align the key as shown, and slide it onto the connector. This should be very much like installing a jumper.

Figure 17 Installing a RAID License Key


When fully installed, the "RAID KEY" label on the daughter card will be covered by the key.

Installing a RAID Battery Backup Unit (BBU)

The BBU is an intelligent battery backup unit that protects disk write cache data during a power loss on the RAID controller for up to 72 hours. We recommend that you replace the BBU once per year or after 1,000 recharge cycles, whichever comes first. Verify whether BBU replacement is required by using the show raid-battery detail command in the CLI.

To remove the RAID license key, perform the following procedure in reverse order.

To install a RAID BBU, follow these steps:


Step 1 Using UCS Manager, perform a graceful shutdown of the server. Without a graceful shutdown, data may be permanently lost.

Step 2 Remove the blanking plate, if present, from the BBU bay at the right of the server.

Step 3 Slide the BBU unit in partially, and align the ejector lever as shown in Figure 18.

Figure 18 Slide in the BBU

.

Step 4 Continue pressing the BBU in until the ejector lever folds below the carrier tray. The BBU rear connector should automatically seat with the RAID controller at its rear.

Step 5 Secure the BBU in place by tightening the captive screw with a #2 Phillips screwdriver.
