Chapter 1 System Overview
Installing S25N and S25V Systems 9
The S25N (Cat# S25-01-GE-24T) and S25V (Cat# S25-01-GE-24V) models of the S-Series are high
performance, low cost, stackable, Layer 2 switch/Layer 3 routers that support 24 built-in 10/100/1000
Base-T ports with four shared 1GbE SFP (small form-factor pluggable) ports, and two rear expansion slots
that can host stacking ports or up to four 10GbE ports. The two differences between the two models are:
•The S25V supp
orts Power over Ethernet (PoE) through its 24 copper ports (see Connecting S25V
Ethernet Ports with PoE on page 38), while the S25N does not.
•The S25V has bo
th AC (470W) and DC power inputs, while the S25N has two AC inputs (150W+150W).
See Supplying Power on page 29. The S25V can also use the Force1
0 470W Redundant DC Power
Supply (see Chapter 4, Installing Backup Power, on page 31) in current sharing (ad
ditive) mode.
Figure 1 shows the front panel of the S25V. The S25N has almost the same layout, except that the catalog
name differs, and an AC2 status LED replaces the DC status LED.
