1 Safety
1.1 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.
1.1.1 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.
1.1.2 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.
1.2 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.
1.3 ESD Prevention
1.3.1 Preventing Electrostatic Discharge
Electrostatic charges that build up on people and conductorsdamage or shorten the lifespan of the
main board and electrostatic-sensitive components.
To prevent electrostatic damage, follow these guidelines:

1-2
•
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.
1.3.2 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.

2 Overview of the BT1004E Ethernet Cascading
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.
•ICMs supported by the chassis are classified into switching modules and straight-through
modules (also known as cascading modules in some manuals). BT1004E is a type of
cascading module. The ICM module, straight-through module, and cascading module
mentioned in this document refer to the BT1004E Ethernet cascading module.
Product Overview
H3C UniServer BT1004E is an Ethernet cascading module for the H3C UniServer B16000 blade
chassis (4*(4*25 GE)). It provides an external data interface, which enables direct connection of
parallel cables to the Ethernet Mezz NIC port of the blade server. BT1004E is applicable to the
high-density scale-out networking solution for B16000. By cascading to ToR switches, BT1004E
provides unified multi-frame deployment management. For details, see Deployment Guide for the
H3C UniServer B16000 High-density Scale-out Networking.
Note
Unlike switching modules, cascading modules only transmit data between blade servers and
external networks without the need to process the data.
•The cascading module has four QSFP28 ports, each of which can be split into four logical
ports. The port speed is 10 Gb or 25 Gb, which can be switched through the OM management
software.
Figure 2-1 shows the appearance of the BT1004E.

on the OM Web page.

2-4
•
A: Defaults to 1; cannot be edited.
•
B: Indicates an internal or external port. 0 indicates an internal port, and 1 indicates an
external port. The cascadingmodule does not have an internal port, so this item number is 1.
•
C: Indicates the sequence number of the cascading module ports. Every four ports constitute
a group, which corresponds to one external QSFP28 port.
