To identify the product code of your switch, use the product barcode on its rear panel.
In this document, if these switches are referred to by their switch model, the information applies to all
the product codes. If these switches are referred to by a product code, the information applies only to
the switches with that product code. For example, the S6850-56HF switch model is available with the
LS-6850-56HF, LS-6850-56HF-H1, or LS-6850-56HF-H3 product code. If the switch is referred to as
the S6850-56HF switch, the information applies to the S6850-56HF switch with either of the codes. If
the switch is referred to as the S6850-56HF (LS-6850-56HF) or LS-6850-56HF switch, the
information applies only to the S6850-56HF switch with the LS-6850-56HF product code.
NOTE:
•
To obtain the purchase information, see the product data sheet at
https://www.h3c.com/en/Products_and_Solutions/InterConnect/Switches/ and pay attention to
