Q. What are the advantages of Cisco Catalyst 2960 PoE switches and Cisco Catalyst
3560/3750 PoE switches?
A. The Cisco Catalyst 2960 Series PoE switches with intelligent services are ideally suited for
small branch offices that can benefit from converged networks. The Cisco Catalyst 2960
Series provides enhanced security, scalable management, and unified network services for
applications such as unified communications and mobility. The Cisco Catalyst 3750 and 3560
with advanced intelligent services are better suited for enterprise and midmarket campus
wiring closets as well as large branch offices. The Cisco Catalyst 3750 and 3560 Series
Switches provide investment protection and deliver increased availability and scalability
through advanced Layer 3 services, advanced security such as man-in-the-middle attack
threat mitigation features, and increased control for applications such as Cisco
TelePresence™.
Q. What are dual-purpose uplinks?
A. A dual-purpose uplink is a combination of one 10/100/1000-TX copper port and one SFP-
based Gigabit Ethernet port. One of these two ports can be used at a time. This added uplink
flexibility allows cost-effective use of high-density, fiber-uplink-based stacks. Dual-purpose
uplinks also offer a full-duplex, gigabit-speed trunk for a Cisco Catalyst 2960 Series Switch
stack.
Q. What SFP transceivers are supported on the Cisco Catalyst 2960 Series?
A. Cisco Catalyst 2960 Series Switches support a wide range of SFP transceivers, including
1000BASE-SX, 1000BASE-BX, 1000BASE-LX/LH, 1000BASE-ZX, 1000BASE-T, coarse
wavelength division multiplexing (CWDM), 100BASE-FX, 100BASE-LX10, and 100BASE-BX.
Table 2 lists the SFP transceivers supported.

*Note: GLC-T and GLC-GE-100FX are not supported on the Cisco Catalyst 2960-8TC-S, 2960-8TC-L, and
2960G-8TC-L switches. For 100BASE-FX connectivity, use the GLC-FE-100FX instead for the compact
switches.
Q. Do Cisco Catalyst 2960 Series Switches have redundant power supply (RPS) support?
A. Yes. The following Cisco Catalyst 2960 Series Switches have RPS support:
●
Cisco Catalyst 2960-24TT-L
●
