Cisco ONS 15530 Components
Table 1-4 shows the pinouts of the console and auxiliary ports.
CompactFlash Card Slot
A CompactFlash card slot (see Figure 1-11) can store the Cisco IOS image or a system configuration file
on a CompactFlash memory card. The system can also boot from the software stored on the
CompactFlash memory card.
OSC Modules and Carrier Motherboards
The OSC (optical supervisory channel) module supports an optional out-of-band management channel
for communicating between systems on the network. Using a 33rd wavelength (channel 0), the OSC
allows control and management traffic to be carried without requiring a separate Ethernet connection to
each Cisco ONS 15530 in the network. Up to two OSC modules can be installed in the carrier
motherboard, one module for the west direction and one for the east direction.
The OSC always terminates on a neighboring node. By contrast, data channels may or may not be
terminated on a given node, depending on whether the channels on the OADM modules are treated as
either express (pass-through) or add/drop channels.
Figure 1-12 shows the front panel of the OSC module.
