Chapter 1 System Overview 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 supports 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 both 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 Force10 470W Redundant DC Power Supply (see Chapter 4, Installing Backup Power, on page 31) in current sharing (additive) 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.

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
supports 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 both 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 Force10 470W Redundant DC Power
Supply (see
Chapter 4, Installing Backup Power, on page 31
) in current sharing (additive) 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.
