  • Cisco C841M-4X/K9 ISR
  • Cisco C841M-8X/K9 ISR

Cisco C841M-4X/K9 ISR has four GE LAN ports and Cisco C841M-8X/K9 ISR has eight GE LAN ports.

Note For compliance and safety information, see Regulatory Compliance and Safety Information for Cisco 800 Series Routers.

This chapter contains the following sections:

General Description

The Cisco 800M Series ISR is a modular router that provides 3G, Gigabit Ethernet, and Serial WAN connectivity options. The Cisco 800M Series ISR has four or eight Gigabit Ethernet LAN ports and two Gigabit Ethernet WAN ports.

The Cisco 800M Series ISR has two modular WAN slots for flexibility to connect branch to data center through field replaceable and non-hot-swappable WAN connectivity modules. The Cisco 800M Series ISR supports 3G GSM/CDMA WWAN module and serial WAN module.

The Cisco 800M Series ISR can be powered by an (included) external AC adapter.

  • 2x GE Enabled WAN (1000/100/10 Base T)
  • Cisco C841M-4X/K9 ISR has 512 MB DRAM
  • Cisco C841M-8X/K9 ISR has 1 GB DRAM
  • 8 MB of boot flash
  • 2 GB NAND Flash
  • AC Power Brick (Adapter (100 -240 AC and 12V 2.5 A DC)
  • Built-in Grounding
  • Rack Mount, Wall Mount, or Desktop Mount
  • LED indicators for the platform
  • Modular WAN slots for 3G and serial modules.

3G Wireless WAN Module

Cisco 800M Series ISRs support GSM and CDMA 3G Wireless WAN networks through the pluggable 3G Wireless WAN module. 3G WWAN module is based on Sierra Wireless 9090 modem and technology mode is auto selected based on the current active firmware.

The following table lists the GSM/CDMA modes and frequency bands supported by the 3G WWAN module.

Table 1-1 Supported Cellular Modes and Frequencies
Mode
Frequency

GPRS/EDGE

850/900/1800/1900 MHz

WCDMA

800/850/1900/2100 MHz

CDMA (1xRTT/EVDO Rev A)

800/1900 MHz

Some of the features supported by 3G WWAN module is given as follows:

  • Dual SIM
  • SIM lock and unlock capabilities
  • Auto-switch failover between primary and backup link

Antenna

The Cisco 800M Series ISR supports 3G external antenna. The Cisco 800M Series ISR provides two standard panel-mount TNC connectors on the 3G WWAN module to support 3G. The main antenna is used as the primary 3G antenna. The second can be used as a diversity receive only 3G antenna. For information about the location of the antenna, see Figure 2-11.

 

Serial WAN Module

The Cisco 800M Series Integrated Services Router (ISR) provides serial WAN connectivity to remote

sites through the pluggable, serial WAN interface module.

The following are some of the features supported by Serial WAN module:

  • Supports the following serial protocols:

– EIA-232

– EIA-449

– EIA-530

– EIA-530A

– V.35

– X.21

  • Supports synchronous speed of up to 8 Mbps
  • Supports asynchronous speed of up to 115.2 kbps
  • Supports network clock synchronization

LEDs

The Cisco 800M Series ISR has LEDs located in the front of the router. The Cisco C841M-4X/K9 ISR has four LAN ports which has four LEDs (0-3) corresponding to each LAN port. The Cisco C841M-8X/K9 ISR has eight LAN ports which has eight LEDs (0-7) corresponding to eight LAN ports.

Both Cisco C841M-4X/K9 ISR ISR and Cisco C841M-8X/K9 ISR has two LEDs for modules (SLOT 0 and SLOT 1), and two WAN LEDs. There are two LEDs to represent PPP and VPN as well.

Table 1-2 describes the LEDs for the Cisco 800M series ISR.
