Safety Instructions
Electrostatic Discharges (ESD)
A sudden electrostatic discharge can destroy sensitive components. Proper packaging and earthing
rules must therefore be observed. Always take the following precautions.
•Transport boards and cards in electrostatically secure containers or bags.
•Keep electrostatically sensitive components in their containers until they arrive at an
electrostatically protected workplace.
•Only touch electrostatically sensitive components when you are properly earthed.
•Store electrostatically sensitive components in protective packaging or on anti-static mats.
Grounding Methods
The following measures help to avoid electrostatic damages to the device:
•Cover workstations with approved antistatic material. Always wear a wrist strap connected to
the workplace as well as properly grounded tools and equipment.
•Use antistatic mats, heel straps, or air ionizers for more protection.
•Always handle electrostatically sensitive components by their edge or by their casing.
•Avoid contact with pins, leads, or circuitry.
•Turn off power and input signals before inserting and removing connectors or connecting
test equipment.
•Keep the work area free of non-conductive materials such as ordinary plastic assembly aids
and Styrofoam.
•Use field service tools such as cutters, screwdrivers, and vacuum cleaners which are
conductive.
•Always place drives and boards PCB-assembly-side down on the foam.

Introduction
The HUB4SSBA is a SuperSpeed 4-Port USB 3.1 Gen 1 hub. Supported in all USB aware operating systems,
the HUB4SSBA requires no separate software drivers and is easy to install.
The HUB4SSBA integrates SeaLATCH™ USB 3.1 Gen 1 ports, which are fully compatible with standard USB
cables. When used with the optional USB cable with a SeaLATCH type B USB connector, the metal
thumbscrew provides a secure metal-to-metal connection to the hub and prevents accidental cable
disconnection. The hub’s four SeaLATCH type A USB connectors can secure USB peripherals to the hub in
the same way.
