Cisco is a respected name in the technology device space, creating products that fill server rooms and data centers across the globe. Integrated Services Routers (ISRs) allow Cisco to serve the small business market, which has increasingly begun relying on cloud services for their application and file storage needs. With its ISRs, Cisco helps network administrators efficiently manage the activities that are so prevalent in business environments today, including videoconferencing and other high-bandwidth activities.
For the past 25 years, Cisco has served as an innovator in network technology. As the market has changed, Cisco has evolved with it, striving to meet the demands of businesses of all sizes. For every large corporation in search of a router to support its global enterprise, there’s at least one small business in need of a solution to power its own daily operations.
Cisco offers several models of ISRs, each varying slightly in its features. Whether you choose a new or refurbished model for your business needs, its important to learn as much as possible about the features of each model to choose the right one to match your own unique environment. Here are a few specifics of the different types of ISRs offered through Summit Information Resources.
Cisco 1900 Series
This line of routers is designed to meet the needs of an SMB business. Within the 1900 series, there are two popular models:
1921—This router has two slots for Enhanced High-Speed WAN Interface Cards (EHWIC) and one compact flash slot.
1941—This router has three EHWIC slots and two compact flash slots. A single Internal Service Module (ISM) slot is available on this model. This model also comes with a wireless option for server rooms that take advantage of wireless technology to reduce cables.
Cisco 2900 Series
Cisco gears this series to its medium- to large-size businesses. This series has four EHWIC slots. Routers in this series numbered 2911 and greater add a Service Module (SM) slot. The 2900 series also comes with two compact flash slots and either two or three Packet Voice Digital Signal Processor Module (PVDM) slots.
In addition to an SM card, the model with an SM slot will also take a network module (NM). That model also has the option of an Internal Services Module. With the 2911 series or higher, administrators can also choose to use a Redundant Power Series (RPS) with an RPS adaptor.
Cisco 3900 Series
Like the 2900 series, the 3900 series is for large-size businesses, but it also is ideal for enterprise locations. The 2900 series comes with three EHWIC ports, two Small Form-Factor Pluggable (SFP) ports, and four Gigabit Ethernet ports. This series also comes with three PVDM slots, two compact flash slots, and an optional dual power supply for protection against power outages.
Ciscos line of Integrated Services Routers provides the latest connectivity technology for businesses of all sizes. Network administrators can optimize their environment at minimal expense by choosing the router that has exactly the slots they need for each rack.
