Cisco Catalyst 2955 Technical Q&A

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

A.Connect two independent 24V power sources to the Cisco Catalyst 2955 and configure the switch for dual-power intake. Each supply is monitored, and alarms can be generated if one source fails.

Q.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?

A.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.
