System Safety

2-1 Electrical Safety Precautions

Basic electrical safety precautions should be followed to protect yourself from harm and
the SuperBlade from damage:

• Be aware of how to power on/off the enclosure power supplies and the individual
blades as well as the room's emergency power-off switch, disconnection switch or
electrical outlet. If an electrical accident occurs, you can then quickly remove power
from the system.

• Do not work alone when working with high voltage components.

• Power should always be disconnected from the blade module when removing or
installing such system components as the mainboard, memory modules and
processors.

• When working around exposed electrical circuits, another person who is familiar
with the power-off controls should be nearby to switch off the power if necessary.

• Use only one hand when working with powered-on electrical equipment. This is to
avoid making a complete circuit, which will cause electrical shock. Use extreme
caution when using metal tools, which can easily damage any electrical components
or circuit boards they come into contact with.

• Do not use mats designed to decrease electrostatic discharge as protection from
electrical shock. Instead, use rubber mats that have been specifically designed as
electrical insulators.

• The power supply power cords must include a grounding plug and must be plugged
into grounded electrical outlets. Power input requires 110-240 V AC, depending upon
your power supply module.

• Mainboard Battery: This battery must be replaced only with the same or an
equivalent type recommended by the manufacturer (CR2032 Lithium 3V battery).
Dispose of used batteries according to the manufacturer's instructions.

WARNING: There is a danger of explosion if the onboard battery is installed
upside down, which will reverse its polarities.

• Mainboard replaceable soldered-in fuses: Self-resetting PTC (Positive Temperature
Coefficient) fuses on the mainboard must be replaced by trained service technicians
only. The new fuse must be the same or equivalent as the one replaced. Contact
technical support for details and support.

2-1

SBI-7426T-S3 Blade Module User’s Manual

2-2 General Safety Precautions

Follow these rules to ensure general safety:

• Keep the area around the SuperBlade clean and free of clutter.

• Place the blade module cover and any system components that have been removed
away from the system or on a table so that they won't accidentally be stepped on.

• While working on the system, do not wear loose clothing such as neckties and
unbuttoned shirt sleeves, which can come into contact with electrical circuits or be
pulled into a cooling fan.

• Remove any jewelry or metal objects from your body, which are excellent metal
conductors that can create short circuits and harm you if they come into contact with
printed circuit boards or areas where power is present.

• After accessing the inside of the system, replace the blade module's cover before
installing it back into the blade enclosure.

2-3 Electrostatic Discharge Precautions

Electrostatic discharge (ESD) is generated by two objects with different electrical
charges coming into contact with each other. An electrical discharge is created to
neutralize this difference, which can damage electronic components and printed circuit
boards.

The following measures are generally sufficient to neutralize this difference before
contact is made to protect your equipment from ESD:

• Use a grounded wrist strap designed to prevent static discharge.

• Keep all components and printed circuit boards (PCBs) in their antistatic bags until
ready for use.

• Touch a grounded metal object before removing the board from the antistatic bag.

• Do not let components or PCBs come into contact with your clothing, which may
retain a charge even if you are wearing a wrist strap.

• Handle a board by its edges only; do not touch its components, peripheral chips,
memory modules or contacts.

• When handling chips or modules, avoid touching their pins.

• Put the mainboard and peripherals back into their antistatic bags when not in use.

• For grounding purposes, make sure the blade enclosure provides excellent
conductivity between the power supplies, the blade modules and the mainboard.

2-4 Operating Precautions

Care must be taken to assure that the cover of the blade unit is in place when the blade
is operating to assure proper cooling. Out of warranty damage to the blade can occur if
this practice is not strictly followed.

Any drive carrier without a hard drive installed must remain fully installed in the drive bay
when the blade module is operating to ensure proper airflow.

2-2

Chapter 3

Setup and Installation

3-1 Overview

This chapter covers the setup and installation of the blade module and its components.

3-2 Installing Blade Modules

Up to fourteen SBI-7426T-S3 blade modules may be installed into a single blade
enclosure (depending upon your enclosure and blad). Blade modules with Windows and
Linux operating systems may be mixed together in the same blade enclosure.

Powering Up a Blade Unit

Each blade unit may be powered on and off independently from the rest of the blades
installed in the same enclosure. A blade unit may be powered up in two ways:

• Press the power button on the blade unit.

• Use IPMIView or the web-browser based management utility to apply power using
either a CMM module, or by the use of the onboard BMC chip in the blade module.

Powering Down a Blade Unit

A blade unit may be powered down in either of five ways:

• Press the power button on the blade unit.

• Use IPMIView or the web-browser based management utility to power down (if you
have Operator or Admin privileges on the CMM).

• Use IPMItool when connected to the CMM to power down (if you have Operator or
Admin privileges on the CMM).

• Use IPMIview or a browser connected to the onboard BMC chip attached to the
blade to power down.

• Use IPMItool to use a Command Line Interface (CLI) to the onboard BMC chip (if
you have Operator or Admin privileges).

Removing a Blade Unit from the Enclosure

Although the blade system may continue to run, individual blades should always be
powered down before removing them from the enclosure.

Removing a Blade Unit from the Enclosure

1. Power down the blade unit (see "Powering Down a Blade Unit" above).

2. Squeeze both handles to depress the red sections then pull out both handles
completely and use them to pull the blade unit from the enclosure.

3-1

SBI-7426T-S3 Blade Module User’s Manual

NOTE: Blade Modules can be Hot-Plugged from the enclosure.

Removing/Replacing the Blade Cover

The blade cover must be removed to access the mainboard when you need to install or
remove processors, memory units, the onboard battery and so on.

Removing/Replacing the Blade Cover

1. Remove the blade unit from the enclosure (see "Removing a Blade Unit from the

Enclosure" above).

2. Depress the two buttons on the cover while pushing the cover toward the rear of the
blade unit. When it stops, lift the cover off the blade unit.

3. To replace the cover, fit the six grooves in the cover into the studs in the sides of the
blade, then slide the cover toward the front of the blade to lock it into place.

Installing a Blade Unit into the Enclosure

Make sure the cover of the blade unit has been replaced first before installing a blade
unit in the enclosure.

Installing a Blade Unit into the Enclosure

1. Slowly push the blade unit into its bay with the handles fully pulled out (see

Figure 3-1).

2. When the blade stops, push the handles back in to their locked position, making
sure the notches in both handles catch the lip of the enclosure (see Figure 3-2).

NOTE: Blade Modules can be Hot-Plugged into the enclosure.

WARNING: Use extreme caution when inserting a blade module into the
enclosure. If the blade's power connector becomes damaged, it can damage

pins on other blade bays that it is inserted into.

Modules) to provide system memory. The DIMMs should all be of the same size and
speed and from the same manufacturer due to compatibility issues. See details
below on supported memory and our web site (www.supermicro.com/products/

superblade for recommended memory.

Populating Memory Slots

The mainboard of a SBI-7426T-S3 blade module has twelve memory slots, depending
upon the blade model. Both interleaved and non-interleaved memory are supported, so
you may populate any number of DIMM slots.

Populating three slots at a time (DIMM1A + DIMM2A + DIMM3A, etc.) with memory
modules of the same size and of the same type will result in dual-channel, interleaved
memory, which is faster than single-channel, non-interleaved memory. See Table 3-1
and Figure 3-5 for details.

For an interleaved configuration, memory modules of the same size and speed
must be installed in pairs. You should not mix DIMMs of different sizes and
speeds.

NOTE: The DIMM slot number specified in Table 3-1 equals the DIMM slot to

be populated. A “---” indicates that the DIMM slot should be left unpopulated.

NOTE: Though multiple DIMM memory module types and speeds may be
supported, you need to use DIMM memory modules of the same speed and
type.
