Table 2.3 - 1000Base-T RJ45 Pin Assignments
Note: “+” and “-” signs represent the polarity of the wires that make up each wire pair.
2.7 Cabling
Use the four twisted-pair, category 5e, or the above cabling for the RJ45 port connections. The cable
between the switch and the link partner (switch, hub, workstation, etc.) must be less than 100 meters (328
ft.) in length.
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical communications
for both telecommunication and data communication applications.
Caution: Please employ optional optical transceiver (SFP/Fixed Fiber) that complies with
IEC-60825-1 and classified as Class 1 laser product.
Attention: Veuillez utiliser un émetteur-récepteur optique en option (SFP/fibre fixe) conforme à
la norme IEC-60825-1 et classé comme produit laser de classe 1.
