To avoid personal injury or damage to the blade server chassis, read the following information carefully before you operate the blade server chassis. Safety precautions in actual operation include but are not limited to safety information mentioned in this document.

General operating safety

· Only H3C authorized or professional engineers are allowed to operate the blade server chassis.

· Place the blade server chassis on a clean, stable table or floor for servicing.

· Ensure that all cables are correctly connected before you power on the blade server chassis.

· Keep the blade server chassis clean and dust-free. Do not place it in a humid place or allow liquids to enter it.

· Gently and slowly transport or place the device with force evenly distributed.

· To avoid personal injury from hot surfaces, allow the blade server chassis and its internal modules to cool before touching them.

· Do not block air vents on the device to avoid damage to the device due to insufficient heat dissipation. When the blade server chassis and other devices are stacked on each other in the rack, reserve clearance of over 2 mm (0.09 in) in the vertical direction between two devices.

Electrical safety

· To avoid personal injury or damage to the device, always use the power cords that came with the blade server chassis.

· Do not use the power cords that came with the blade server chassis for any other devices.

· Power off the device when installing or removing any components that are not hot swappable.

· Carefully check any potential hazards in the work area, for example, whether the blade server chassis is grounded or reliably grounded, and whether the ground is wet.

· Do not work alone when performing live-line maintenance.

· The device supports multiple power inputs. When the device is powered off, check whether all power supplies are turned off.

· Connect power cords to different power distribution units (PDUs) in active/standby mode to ensure the reliability of the device.

· When installing the device, ensure that the ground cables are connected first and disconnected last. It is not allowed to damage the ground guide or operate the device without grounding. Check the grounding before operation. Note that the protective grounding conductors of the device installed in a rack must be connected to the grounding system of the blade server chassis, and the auxiliary ground cables must always be kept inside the rack system.

· Before operating the device, ensure that the device is permanently grounded and that the cross-sectional area of the ground cable is not less than 1.5 mm2 or 14 AWG.

Battery safety

The system board contains a system battery, which is designed with a lifespan of 5 to 10 years.

If the device no longer automatically displays the correct date and time, you need to replace the battery. When you replace the battery, follow these safety guidelines:

· Do not attempt to recharge the battery.

· Do not expose the battery to a temperature higher than 60°C (140°F).

· Do not disassemble, crush, puncture, short external contacts, or dispose of the battery in fire or water.

· Dispose of the battery at a designated facility. Do not throw the battery away together with other wastes.

Rack mounting recommendations

Rack safety recommendations

· Install the blade server chassis in a standard 19-inch rack.

· Ensure that the leveling jacks are extended to the floor and the full weight of the rack rests on the leveling jacks.

· Couple the racks together in multi-rack installations.

· Stabilize the rack when the extending or pushing the blade server chassis.

· For rack stability, ensure that only one unit is extended at a time. Otherwise, the rack might get unstable.

Installation safety recommendations

· Load the rack from the bottom to the top, with the heaviest hardware unit at the bottom of the rack. Install the devices from the bottom to the top, with the heaviest device installed first.

· When the device is loaded with modules, the handles that came with the device are only used to adjust the device position instead of lifting the device. Use tools such as forklift to lift the blade server chassis.

· When moving the device, hold the handles of the device or the bottom edge of the device instead of the handles of modules (such as Power supply, fan module, hard disk, or main board) installed in the device.

· Get help to lift and stabilize the blade server chassis during installation or removal, especially when the blade server chassis is not fastened to the slide rails. As a best practice, a minimum of four people are required to safely lift the blade server chassis. One more person might be required to help align the blade server chassis if the blade server chassis is installed higher than chest level.

· When using tools, follow the correct operation methods to avoid damage to the device.

· To maintain sufficient heat dissipation, install blanks in empty slots.

ESD prevention

Electrostatic charges that build up on people and conductors damage or shorten the lifespan of the main board and electrostatic-sensitive components.

Preventing electrostatic discharge

To prevent electrostatic damage, follow these guidelines:

· Transport or store the device with the components in ESD bags.

· Keep the electrostatic-sensitive components in the ESD bags until they arrive at an ESD-protected area.

· Place the components on a grounded table before taking them out of their ESD bags.

· Avoid touching pins, cables, or circuitry of the components without taking any ESD prevention measures.

· Ensure that you are reliably grounded when touching an electrostatic-sensitive component or assembly.

Grounding methods to prevent electrostatic discharge

The following are grounding methods that you can use to prevent electrostatic discharge:

· Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

· Take adequate personal grounding measures, including wearing antistatic clothing and static dissipative shoes.

· Use conductive field service tools.

· Use a portable field service kit with a folding static-dissipating work mat.

Installation Guidelines

Blade Server Installation Guidelines

CAUTION:

Do not install a half-width blade server in an area where no vertical divider is installed. A forced installation might damage the blade server connector.

As shown in Figure 7, the chassis is divided into four areas by three fixed dividers. Each area has one removable vertical divider which divides the slots in the area from full width to half width.

· In each area, you can install a maximum of four half-width and full-height blade servers or two full-width and full-height blade servers. Do not mix half-width and full-width blade servers in the same area.

· As a best practice, install blade servers into the slots from left to right and bottom to top.

¡ Install half-width and full-height blade servers in the slot sequence of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16, as shown in Figure 8.

¡ Install full-width and full-height blade servers in the slot sequence of 1, 3, 5, 7, 9, 11, 13, and 15, as shown in Figure 9.

· To mix half-width and full-width blade servers on the same chassis, first install half-width blade servers from left to right and bottom to top and then install full-width blade server from bottom to top.

Power supply installation guidelines

As shown in Figure 14, up to six power supplies can be installed in the blade server chassis. The power supplies support no redundancy, N+1 redundancy, and N+N redundancy modes.

As a best practice, install power supplies from bottom to top and from left to right, in the sequence of 1, 2, 3, 4, 5, and 6.

The number of power supplies to be installed is related to the total power consumption of the blade server chassis. You can determine the number of power supplies required based on the total power consumption of the blade server chassis. Table 8 lists the maximum power of major modules of the blade server chassis. Table 9 to Table 13 describe the power supply configuration policies.

Make sure the models of all power supplies installed in the blade server chassis must be the same.

Do not use third-party power supplies. If third-party power supplies are used, hardware damage might occur.

In N+N redundancy mode, when power supplies are connected to external power sources, connect power supplies in slots 1, 3, and 5 to a power source, and those in slots 2, 4, and 6 to another power source.

The power supplies are hot swappable.

Internal Networking

OM Modules

The blade server chassis manages the modules through the OM module, as shown in Figure 16.

· Two OM modules internally interconnect with each other to work in active/standby mode.

· The OM module connects to the BMCs of blade servers, BMCs of AE modules, and AMCs of interconnect modules through the internal GE management plane for out-of-band management.

· The OM module communicates and synchronizes information with the LCD module through the TTL serial port.

The LCD module and AE1 module share one slot (E1). Only one of these two modules can be installed in the slot at a time.

· The OM module manages the power supplies and fan modules through the internal I2C bus.

· Each OM module has one management port (MGMT), one cascading port (STACK), and four service ports. From the management port, you can log in to chassis management software. The cascading port is used for multi-chassis cascading. The service ports can connect the blade servers to the external network.

Figure 16 Connections of OM modules with internal modules of the blade server chassis

AE Modules

As shown in Figure 17, in the chassis, the AE module uses the four embedded network ports to connect OM modules and interconnect modules through the midplane. It connects the active and standby OM modules from the GE ports and the interconnect modules in slots 1 and 4 from the 10-GE ports. You can log in to the AE module FIST management software from the management port on the OM module or an Ethernet port on an interconnect module front panel.

Figure 17 Internal connections of the AE modules

Interconnect modules and blade servers

The number of supported Mezz network adapters and the internal connections between Mezz network adapters and interconnect modules vary with blade server models, as shown in Table 14.

Mechanically active substance buildup on the chassis might result in electrostatic adsorption, which causes poor contact of metal components and contact points. In the worst case, for example, the relative humidity in the room is low, electrostatic adsorption can shorten the lifespan of the device and easily cause communication failure.

Table 16 describes concentration and particle diameter limits of mechanically active substance in the equipment room.

Table 16 Mechanically active substance concentration limit in the equipment room

Substance (Diameter)	Concentration Limit	Unit
Dust particles (≥ 5 μm)	≤ 3×104 (No visible dust on desk within three days)	Particles/m3
Dust (suspension) (≤ 75 μm)	≤ 0.2	mg/m3
Dust (sedimentation) (75 μm to 150 μm)	≤ 1.5	mg/(m2h)
Sand (≥ 150 μm)	≤ 30	mg/m3

The equipment room must also meet limits on salts, acids, and sulfides to eliminate metallic corrosion and premature aging of some components. Table 17 lists limits of harmful gases (such as SO2, H2S, NO2, NH3, and Cl2) in an equipment room.

Table 17 Harmful gas limits in an equipment room

Gas	Maximum concentration (mg/m3)
SO2	0.2
H2S	0.006
NO2	0.04
NH3	0.05
Cl2	0.01
