Configurations

The CGS 2520 (Figure 2) includes the following configurations:

●

Cisco CGS-2520-24TC: Rugged Ethernet switch with 24 10/100BaseTX ports and two dual-purpose

Gigabit Ethernet uplinks (dual-purpose Gigabit Ethernet uplinks allow the user to activate either copper or

fiber media). There are two 10/100/1000BaseTX ports and two 100/1000 Small Form-Factor Pluggable

(SFP) ports on board. The user can select two fiber ports, two copper ports, or a combination of fiber and

copper ports. The Layer 2 LAN Base image is included.

●

Cisco CGS-2520-16S-8PC: Rugged Ethernet switch with 16 Fast Ethernet (FE) SFP ports, eight

10/100BaseTX/PoE ports, and two dual-purpose Gigabit Ethernet uplinks. The Layer 2 LAN Base image is

included.

●

PWR-RGD-LOW-DC: Low DC (24/48V) power supply module for the CGS 2520 switch, which can also be

used in the CGR 2010 router.

●

PWR-RGD-AC-DC: High AC/DC (88-300VDC/85-264VAC) power supply module for the CGS 2520 switch,

which can also be used in the CGR 2010 router.

The CGS 2520 offers two different Cisco IOS Software feature images: LAN Base and IP Services. The LAN Base

image offers advanced QoS, flexible VLAN handling, SCADA protocol classification support, Resilient Ethernet

Protocol (REP) for improved convergence time in ring topologies, Flexlink for fast failover in hub-and-spoke

topologies, and comprehensive security features. In addition, the IP Services image adds advanced Layer 3

features such as support for advanced IP routing protocols, Multi-VPN Routing and Forwarding Customer Edge

(Multi-VRF CE/VRF-Lite), and policy-based routing (PBR).

The SFP-based uplink ports accommodate a range of industrial-grade SFP transceivers, including 1000BASE-SX,

1000BASE-LX, 1000BASE-ZX, 100BASE-FX, and 100BASE-LX10.
