What memory upgrade options are available on the Cisco ISR4351/K9?
The 4000 Series has separate data and control-plane memory. The control-plane memory comes with 4 GB as the default, and is upgradable up to 16 GB based on various platforms. The data-plane memory comes with 2 GB as the default and is not currently upgradable.
How many dual inline memory modules (DIMMs) does the Cisco ISR4351/K9 have?
The Cisco ISR4351/K9 has two DIMMs.
In the case of control-plane memory, can I put a 4-GB DIMM in one slot and a 2-GB DIMM in the other slot?
No. the 4000 Series expects both DIMM slots to have the same size of memory; as an example, it must have either 4-GB memory in both slots for a total of 8 GB of control-plane memory, or 2-GB memory in both slots, for a total of 4 GB of control-plane memory. This setup is necessary because these platforms interleave memory devices for faster access.
Can I use the NIMs on the Cisco 1900, 2900, and 3900 Series ISRs?
No.The NIMs are designed for a newer architecture and will not work on the Cisco 1900, 2900, and 3900 Series ISRs.
What type of backplane is used between components in the Cisco 4000 Series?/p>
The 4000 Series uses multigigabit fabric (MGF) for Layer 2 connectivity between the modules. On the 4451-X, the MGF can provide either 2 Gbps to all NIM slots or up to 10 Gbps to all SM-X slots. The MGF is completely nonblocking and can forward in excess of 50 Gbps.
What power cables work with the Cisco 4000 Series?
All power-supply options for the 4000 Series use a standard IEC C13 connector. No special IEC C15 cord is necessary for the Power over Ethernet (PoE) power supply because higher-efficiency power supplies (85 percent) are used in the 4000 Series. This cord thus helps lower the maximum current the power supplies can draw.
With redundant power supplies, can we switch the power to primary when it fails and the router is running on the secondary power supply?
There is no concept of primary or secondary power supply for the Cisco 4451-X and 4351. The power supplies are simply redundant, so that when one fails the other power-supply unit (PSU) takes over by transparently providing power to the entire system. No switching or intervention is required. Both share the load when running in the system; however, when one fails the other provides power to the complete unit. When the failed PSU is replaced with a new PSU in the system, the two power supplies are redundant.
How does the system fan speed vary?
The Cisco 4000 Series ISRs use both an inlet temperature and an altitude sensor to determine the best fan-speed setting. There are four different inlet temperature ranges and five different altitude ranges for a total of 20 possible different fan-speed settings. The addition of an altitude sensor is an industry first for a branch-office platform. With altitude data incorporated into the fan speed, the system can account for the density of air cooling in order to select the most efficient and quietest fan-speed setting. All system fans run at the same speed.
What is the purpose of the GigabitEthernet0 on the Cisco 4000 Series?
The GigabitEthernet0 is the dedicated management port on the Cisco 4000 Series. This interface connects directly to the control-plane CPU and is ideal for managing the router through Telnet, Secure Shell (SSH) Protocol, Simple Network Management Protocol (SNMP), and other management protocols. It is also ideal for downloading software images, uploading logs, and connecting to other management devices such as RADIUS, Network Time Protocol (NTP), Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), and TACACS servers. This interface should never be used for forwarding normal data traffic through the system because every packet goes directly to the control-plane CPU, bypassing the platform data plane. Because of this sensitivity, G0 is in a dedicated Mgmt-Intf Virtual Route Forwarding (VRF) port by default. This setup prevents accidental routing mistakes that could cause data traffic to be routed to the management network.
