SFP Module Patch Cable

The switch uses an SFP-module patch cable, a 0.5-meter, copper, passive cable with SFP module
connectors at each end (see Figure 1-3). The patch cable connects two switches in a cascaded
configuration.
Figure 1-3 SFP-Module Patch Cable
See the “Inserting and Removing the SFP Module Patch Cable” section on page 2-21 for information
about using the SFP module patch cable.
You can order this cable (part number CAB-SFP-50CM=).
Power-Input Terminal
The power-input terminal provides screw terminals for the AC and DC power connections. The switch
can operate with one or two power supplies. If one of the power sources fail, the other continues to power
the switch. See Chapter 3, “Power Supply Installation,” for information.

Alarm Ports
The switch has four alarm inputs and one alarm output. The alarm setting is open or closed.
• Open means that the normal condition has current flowing through the contact (referred to as a
normally closed contact). The alarm is generated when the current stops.
• Closed means that no current flows through the contact (referred to as a normally open contact). The
alarm is generated when the current flows.
