VCCI Statement

Pre-Standard IEEE 802.3at and Cable Temperatures

3Com recommends that you do not operate your cables above 50°C (122°F) if you are using the higher power mode capability of the 3CBLSF26PWR. This switch can deliver up to 29.6 W per port (measured at the PD, assuming 100 m Cat 5E cable connected between the PD and the Switch 2426-PWR, subject to power being available), and in certain cable installations this may result in increased cable temperatures. If you are in anyway unsure of how your cable installation is laid out, you should contact an approved cable installation company for advice prior to using the higher power modes.

This guidance is only applicable to pre-standard 802.3at operation. When operating in 802.3af (15.4 W) mode it is not necessary to run at lower than rated cable temperatures.
