Cisco 1921-K9 & Cisco 1921-SEC-K9 overview & Specs

It's all known that Cisco 1921 builds on the best-in-class. All Cisco 1900 Series Integrated Services Routers offer embedded hardware encryption acceleration, and advanced security services. In addition, the platforms support the industry's widest range of wired and wireless connectivity options such as Serial, T1/E1, xDSL, Gigabit Ethernet, and third-generation (3G) wireless. Now, let’s share Cisco 1921 full and simple tutorial in diagram form.
Cisco 1921/K9 router features
LED area description:

· SYS: Solid green ---normal operation.
          Blinking green ---System is booting or is in ROM monitor mode.
          Amber ---System error.
          Off ---Power is off or system board is faulty.
· ACT: Solid or blinking ---any packets are transmitted/received on any WAN/LAN, or when monitoring system activity.

· PoE: Green ---PoE is available.
          Amber ---Power supply is not supplying PoE power.

 S (Speed): 1 blink + pause ---GE port operating at 10 Mb/s.
                    2 blink + pause ---GE port operating at 100 Mb/s.
                    3 blink + pause ---GE port operating at 1000 Mb/s.
· L (Link): Green ---GE link is established.
                 Off ---No GE link is established.

 Note: 

· 1 integrated EHWIC slots for flexible configurations & support of two modules: 
         1 double wide HWIC-D or single wide EHWIC/HWIC module; 
         or 2 single wide EHWIC/HWIC module .
(Each HWIC Slot offers high data throughput capability with up to 1.6 Gbps aggregate towards the router processor and up to 2 Gbps aggregate to other module slots over MultiGigabit Fabric (MGF)).

· 1 AUX port (auxiliary port) ---RJ-45 connectors for Remote configuration.

· GE 0/0 & 0/1---Two Gigabit Ethernet ports (RJ-45 connectors).

· High-speed USB 2.0 ports enable another mechanism secure token capabilities and storage.
