Safety
Safety information
To avoid personal injury or damage to the device, read the following information carefully before you
operate the device. 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 device.
•
Keep the device clean and dust-free. Do not place it in a humid place or allow liquids to enter it.
•
Before powering on the device, ensure that the blade enclosure is securely grounded.
•
To maintain sufficient heat dissipation, use filler panels on idle slots.
Electrical safety
•
Carefully check any potential hazards in the work area, for example, whether the ground is wet
and whether the blade enclosure is grounded or reliably grounded.
•
Do not work alone when performing live-line maintenance.
•
Do not touch the power supply directly or indirectly through conductive objects to prevent
electric shock.
Safety precautions
•
When maintaining the device, place the device on a clean, stable table or floor.
•
To avoid personal injury from hot surfaces or internal components, allow the device and its
internal components to cool before touching them.
•
When using tools to maintain the device, follow the correct operation methods to avoid damage
to the personnel or device.
•
When connecting, testing or replacing optical fibers, do not look directly into the optical fiber
outlet to prevent the laser beam from hurting your eyes.
•
Gently and slowly transport or place the device with force evenly distributed.
ESD prevention
Preventing electrostatic discharge
Electrostatic charges that build up on people and conductors damage or shorten the lifespan of the
main board and electrostatic-sensitive components.
To prevent electrostatic damage, follow these guidelines:
•
Transport or store the device in an ESD bag.
•
Place the device on a grounded table before taking it out of the ESD bag.
•
Avoid touching pins or circuitry of the device without taking any ESD prevention measures.

2
Grounding methods to prevent electrostatic discharge
When removing or installing the device, you can use one or multiple of the following grounding
methods to prevent electrostatic discharge:
•
Wear an ESD wrist strap and ensure that it is reliably grounded. Ensure that the ESD wrist strap
makes good skin contact and can be flexibly stretched out and draw back.
•
In the work areas, wear the ESD clothing and shoes.
•
Use conductive field service tools.
•
Use a portable field service kit with a folding ESD tool mat.

Overview of the BX720E switch module
NOTE:
•
Hardware images shown in this manual are for illustration purposes only. The actual product may
vary.
•
The software UI may be updated from time to time. Please refer to the actual product UI.
•
ICM modules supported by the blade enclosure are classified into switch modules and
straight-through modules (also known as cascading modules in some manuals). T
he BX720E is
a type of switch module. Both ICM and switch modules mentioned in this document refer to the
BX720E.
Product overview
As an Ethernet switching control module inside the blade enclosure, the H3C UniServer BX720E
switch module (BX720E for short) provides data switching functions for servers installed in the front
slots of the blade enclosure and centrally provides external data ports, to achieve the communication
between blade servers and external networks.
Figure 1 shows the appearance of the BX720E.
Figure 1 Appearance
High availability
Redundancy of devices
Up to six switch modules can be installed in a blade server chassis. For more information about the
installation position, see Figure 2. Switch modules in slots 1 and 4, 2 and 5, and 3 and 6 are
interconnected by the internal ports of the switch modules in pairs to form three pairs. Each pair can
be used as a switching plane, and you can configure the pairs of switch modules in active/backup
mode as required.

(6) ICM6 slot
Redundancy of links
Switch modules are connected to blade servers through the mid plane and provide external ports to
achieve uplink connection for blade servers. Aswitch module connects to a blade server through two
internal ports configured in active/backup mode, which ensures high availability of internal links in
the blade server chassis.

Port
This section describes numbering rules, positions, quantity, and other information about the ports of
the switch module.
Port numbering rules
Ports of the switch module are numbered in three dimensions: A, B, and C.
•
A: Indicates the number of the IRF member device. Since the switch module does not have any
IRF by default, the default value of Ais 1.
•
B: Indicates an internal or external port. 0 indicates an internal port, and 1 indicates an external
port.
•
C: Indicates the sequence number of the port.
External ports
