Chapter 1: Overview of the SafeGuard Controller
Figure 3 OAG1000 Front Panel
Each SafeGuard Controller model has secured port pairs that act as bridged ports. These
ports can be configured to be synchronized, so that when one port in the pair comes up,
its paired port comes up. Similarly, when one port in the pair goes down, its paired port
goes down. Within each pair, the top port (odd-numbered) is used to connect the
SafeGuard Controller to the upstream core or distribution switch. The bottom port (even-
numbered port) is used to connect the SafeGuard Controller to the downstream access
(wire-closet) switches. The OAG2400 has 10 core ports and 10 edge ports. The OAG1000
has four network ports and four host ports.
Both SafeGuard Controller models have extensibility ports that include a reserved high-
availability port for connecting a peer SafeGuard Controller of the same type and either
one (OAG1000) or two (OAG2400) ports for monitoring. In addition, the OAG2400 has a
port that is reserved for future use.
lists the functions of the extensibility ports.
Each front-panel port can be customized by inserting the proper SFP module. The SFP
modules supported are single-mode and multi-mode fiber and single-speed and triple-
speed copper modules. You can mix and match different types in the same unit. For more
information about the SFP modules, see
Small Form-Factor Pluggable (SFP) Modules on
To comply with the IEEE 802.3ab standard, by default, the front-panel 10/100/1000 ports
of the SafeGuard Controller are capable of auto-negotiation for speed and duplex
settings. For example, with auto-negotiation enabled by default, the port detects the
interface settings and auto-configures support for the full-duplex or fastest line speed,
