BlackDiamond 6800 Series I/O Modules
The P3cSi and P3cMi Packet over SONET (PoS), modules each have four OC-3 ports that use duplex SC
connectors. The P12cSi and P12cMi PoS modules each have two OC-12 ports that use duplex SC
connectors. The P3cSi and the P12cSi modules support single mode fiber-optic cable only, and the P3cMi
and the P12cMi modules support multimode fiber-optic cable only. These modules connect the switch to
a SONET infrastructure that is used by metropolitan area service providers and operators of server
co-location networks.
In the first application, the metropolitan area network service provider can build service network sites
in various cities, then use PoS modules in a BlackDiamond 6800 series switch to connect those cities to a
carrier's SONET infrastructure.
In the second application, operators of server co-location networks can use PoS modules in
BlackDiamond 6800 series switches to create a SONET-based connection between server co-location
sites. The result is that their network is simpler to manage, and problems can be isolated and resolved
more expediently.
The default configuration of the P3cSi, P3cMi, P12cSi, and P12cMi modules is as follows:
• Are added to the default VLAN as untagged. For P3c modules, only ports 1 and 3 are added to the
default VLAN. Ports 2 and 4 are not added to any VLAN.
• Inherit the properties of the default VLAN (VLANid and so forth).
For optical specifications of the P3cSi, P3cMi, P12cSi, and P12cMi optical interfaces, see Table 123 on
page 358.
PoS Module LEDs
The PoS modules are equipped with two module-level LEDs (STATUS and DIAG) and one port-level
LED for each network interface port on the PoS module (see Figure 162 and Figure 163).
• STATUS LED—Near the top end of the PoS module front panel, near the ejector/injector handle.
This LED indicator is a bi-color LED (displaying in either green or amber) that signals the operating
status of the module as a whole.
• DIAG LED—Beside the STATUS LED. This LED is a single-color LED (displaying in amber only)
that flashes amber when diagnostics are running on the module, and is solid amber if the module
fails the diagnostics.
• Port-level LED—Next to the port number identifying each fiber optic network interface connector on
the front panel of the module. The port LED is a bi-color LED (displaying in either green or amber)
that signals the operating status of that network interface port.
NOTE
During the PoS module boot-up, the STATUS and DIAG LEDs may be incorrectly lit to solid green or
solid amber. The LEDs reflect their true state after approximately 30 seconds when the module has
completed its boot cycle.
For more information about PoS module LED activity, see "I/O Module LEDs" on page 293.
Service Ports
The PoS modules have two front-panel service ports (see Figure 162 and Figure 163): one is a
subminiature DB-9 connector; the other is a micro HD-15 connector.
