Cisco Catalyst 2955 Technical Q&A

If I want to provide redundant power to my Cisco Catalyst 2955 switches, how would I implement this solution?

Connecttwoindependent24V power sources to the Cisco Catalyst 2955 and conﬁgure the switch fordual-power

intake. Each supply is monitored, and alarms can be generated if one source fails.

How can I connect the 100BASE-FX ports of the Cisco Catalyst 2955C-24 to a 100BASE-FX ports device that

has an SC or ST connector?

Fiber patch cables are available from Cisco in one-, three-, or ﬁve-meter lengths for connecting the MT-RJ

connector on your Cisco Catalyst 2955C-24 to another 100BASE-FX device with an SC or ST connector. Table 1

lists the part numbers.
