Cisco2800 Series Router price When working with Cisco networking equipment, understanding the intricacies of slot numbering is crucial for successful hardware installation and configuration. This is particularly true for the popular Cisco 2851 Integrated Services Router. This article delves into the specifics of cisco 2851 slot numbering, providing clear guidance and detailed information to ensure accurate deployment and troubleshooting.

The Cisco 2851 is a robust router designed to offer a flexible platform for various network needs, equipped with multiple expansion options. These expansion capabilities are housed within various slots on the router. Identifying the correct slot for a specific module, such as HWIC-1GE in WIC slot 0, is essential for the device to function as intendedCisco Systems Inc. NSN Parts: CISCO2811-SEC/K9. The number of total expansion slots on a Cisco 2851 can vary, but commonly includes a significant number of multiple expansion slots: 1 NME-XD, 1 EVM, 4 HWICs, 3 PVDMs, 2 AIMs. Some configurations mention a Number of Total Expansion SlotsHow to determine if a switch is layer two or layer three?. 11, while others cite up to Number of Total Expansion Slots: 12.

Decoding Cisco 2851 Slot Identification

The slot numbering on Cisco routers, including the Cisco 2851, often follows a logical pattern but can have nuancescisco 2800 series integrated services routers. Generally, network module and service module slots are numbered from right to left, and bottom to top. However, it's important to be aware that some router models might employ different slot numbering schemes.

For the Cisco 2851, specific slots are designated for different types of modules. For instance, it features 4 HWIC slots, which are used to house High-Speed WAN Interface Cards (HWICs).CISCO2851 Cisco 2851 w/ AC, 2GE, 4HWIC, 3PVDM, 1NME Understanding Interface Numbering within these HWIC slots is keyCisco 2851 Integrated Services Router - CISCO2851-RF. For example, a HWIC-1GE might be installed in a WIC slot 0, and subsequent interfaces would be Port 0/0, Port 0/1, and so on.slot on Cisco integrated services routers.

Understanding Interface and Slot Conventions

The syntax used in Cisco IOS to refer to interfaces often includes the slot and port number.slot. • The EVM supports additional voice services and density without consuming the network-moduleslot(Note: available only onCisco2821 and2851). For a Cisco 2851, an interface might be represented as `GigabitEthernet0/0`, where `0` refers to the interface card slot or onboard port, and the second `0` refers to the specific port on that card. When dealing with modules in WIC slots, the slot numbering is typically `0`, `1`, `2`, etc., corresponding to the physical location* The EVM slot number for both Cisco 2821 and Cisco 2851 routers is designated as "2".. For example, you might see references to slot 0/0 when configuring a VWIC2-2MFT card, with the ports then being `0/0/0` and `0/0/1`.

It's worth noting that for modules that occupy multiple physical slots, the configuration might adjust accordingly. For example, if the slot divider is removed, Slot 1 and slot 2 becomes slot 1, and Slot 3 and slot 4 becomes slot 3.
