Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.

Network modules install directly into slots in the rear of the router. The Cisco 3845 router supports online insertion and removal (OIR, or hot swap) of network modules. The Cisco 3825 router does not support OIR.

Caution The Cisco 3845 router supports OIR with similar modules only. If you remove a network module, along

with any installed WAN or voice interface cards, install another module and card combination exactly like it.

Caution The Cisco 3825 router does not support OIR of network modules. To avoid damaging the module, you

must turn off electrical power and disconnect network cables before you insert the module into a router slot.

Module and Interface Card Capacity

The Cisco 3825 router provides two slots for network modules. The lower network module slot of this router, labeled 1 on the rear panel, can hold either of the following sizes of network modules:

• One single-wide network module

• One extended single-wide network module

The upper network module slot of the Cisco 3825 router, labeled 2 on the rear panel, can hold any of the following sizes of network modules:

• One single-wide network module

• One extended single-wide network module

• One double-wide network module

• One extended double-wide network module

The Cisco 3845 router provides four slots for network modules, labeled 1, 2, 3, and 4 on the rear panel. Each slot can hold either of the following sizes of network modules:

• One single-wide network module

• One extended single-wide network module

Slots 1 and 2 can also be combined to hold either of the following sizes of network modules:

• One double-wide network module

• One extended double-wide network module

Slots 3 and 4 can be combined in the same way to hold one double-wide or extended double-wide network module.

Module and Interface Card Capacity

Note The terms single-wide, extended single-wide, double-wide, and extended double-wide refer to the

physical size of a network module. Enhanced network modules offer additional functionality; this functionality is not directly related to the module’s size.

Note The Cisco 3825 router supports one high-density analog-digital extension module for voice and fax. The

Cisco 3845 module supports two of these modules.

Certain network module configurations require the installation or removal of a slot divider in the module slot. All configurations require blank faceplates or slot adapters to be installed over unused slots for cooling, electromagnetic interference (EMI) reduction, and safety. Procedures for installing network modules, slot dividers, slot adapters, and blank faceplates are described in “Installing Network Modules

in Cisco 3800 Series Routers” and the Cisco Network Modules Hardware Installation Guide.

Interface Cards

Interface cards install either into slots in the rear of the router, or into slots in network modules. Interface cards come in the following types:

• WAN interface card (WIC)

• Voice interface card (VIC)

• Voice/data T1/E1 WAN interface card (VWIC)

• High-speed WAN interface card (HWIC)

Note You can insert any kind of interface card—WIC, VIC, VWIC, or HWIC—into a router HWIC slot.

HWICs must be installed directly into router slots, not into network modules.

The Cisco 3825 router and the Cisco 3845 router each provide four interface card slots, labeled on the rear panel by HWIC and a number. Each slot can be occupied by one single-wide WIC, VIC, VWIC, or HWIC.

In addition, the HWIC 0 and HWIC 1 slots can be combined to hold one double-wide HWIC. The HWIC 2 and HWIC 3 slots can also be combined to hold one double-wide HWIC.

Note Although the HWIC 1 and HWIC 2 slots on the Cisco 3845 router are adjacent to each other, they cannot

be combined to hold a double-wide HWIC.

The maximum capacity of Cisco 3800 series routers for interface cards inserted directly into the chassis is four WICs, VICs, VWICs, or HWICs, or two double-wide HWICs.

Caution Cisco 3800 series routers do not support OIR (hot swap) of interface cards inserted directly into router

slots. You must turn off the router before installing or removing an interface card.

Overview of Cisco 3800 Series Routers

OL-5966-01

Certain interface card configurations require the installation or removal of a slot divider in the router’s interface card slot. All slots must be covered by interface cards or blank faceplates for cooling, electromagnetic interference (EMI) reduction, and safety. Procedures for installing interface cards, slot dividers, and blank faceplates are described in “Installing Interface Cards in Cisco 3800 Series Routers” and the Cisco Interface Cards Installation Guide.

AIMS and PVDMs

Advanced integration modules (AIMs) and packet voice data modules (PVDMs) install into connectors on the router motherboard. AIMs provide hardware-based support for additional features. PVDMs are digital signal processor (DSP) SIMMs that provide voice support. The Cisco 3825 router and the Cisco 3845 router can each accommodate two AIMs and four PVDMs.

Installation, replacement, and removal of AIMs and PVDMs require opening the cover of the Cisco 3825 router, or removing the motherboard of the Cisco 3845 router. For more information, see “Installing and

Upgrading Internal Components in Cisco 3800 Series Routers.”

Port Numbering

Each built-in network port on a Cisco 3800 series router, and each port or interface on a network module or interface card, is identified in Cisco IOS software by an interface type and a number or series of numbers separated by forward slashes (/). Port numbers for Cisco 3800 series routers follow the rules in this section.

Note Port numbering conventions differ for different router series. For routers that are not part of the

Cisco 3800 series, consult your router documentation for port numbering information.

Built-In Ports

Cisco 3800 series routers have two Gigabit Ethernet ports built into the router’s rear panel, labeled 0/0 and 0/1. These numbers are used with the interface-type keyword gigabitethernet to identify the ports in Cisco IOS commands—gigabitethernet 0/0 and gigabitethernet 0/1.

Note If an optional SFP module is installed and selected, it is assigned gigabitethernet 0/0.

Network Module Ports

Ports on network modules inserted into a router slot are numbered slot/port, where slot is the slot number in the router and port is the port number in the network module. For example, port 1 of a Fast Ethernet network module inserted into router slot 2 would be identified as fastethernet 2/1.

The Cisco 3825 router has two slots for network modules. The lower slot is numbered 1 and the upper slot is numbered 2, as labeled on the router’s rear panel. (See Figure 4 on page 3.) The Cisco 3845 router has four slots: 1 at lower right, 2 at lower left, 3 at upper right, and 4 at upper left. (See Figure 8 on

page 5.)

OL-5966-01

Overview of Cisco 3800 Series Routers

Port Numbering

Note In the Cisco 3845 router, double-wide or extended double-wide network modules are identified by slot

numbers 1 and 3.

Ports in a network module are normally numbered from right to left and bottom to top, starting at 0. See the Cisco Network Modules Hardware Installation Guide for more information.

Interface Card Ports

Interface cards can be inserted either directly into a router slot, or into a slot in a network module.

Interface Card in Router

Interface cards inserted directly into a router slot are numbered 0/HWIC-slot/port. HWIC-slot is the HWIC slot in the router—0, 1, 2, or 3, as labeled on the router’s rear panel; port is the port number in the interface card. For example, port 0 of a T1 WIC inserted into router HWIC slot 3 would be identified as t1 0/3/1.

Note Double-wide interface cards use HWIC slot numbers 1 and 3.

Ports in an interface card are normally numbered from right to left and bottom to top, starting at 0. See the Cisco Interface Cards Installation Guide for more information.

Interface Card in Network Module

Some network modules provide their own slots for interface cards. Ports in these interface cards are numbered router-slot/module-slot/port, where router-slot is 1 or 2 for the Cisco 3825 router and 1, 2, 3, or 4 for the Cisco 3845 router; module-slot is the slot in the network module for the interface card; and port is the port number in the interface card. For example, port 0 of a voice interface card in slot 1 of a voice network module in slot 4 of a Cisco 3845 router would be identified as voice 4/1/0.

Note Double-wide or extended double-wide network modules use router slot numbers 2 and 4.

Slots in network modules for interface cards are normally numbered from right to left, starting at 0. Ports in an interface card are normally numbered from right to left and bottom to top, starting at 0. For more information, see the Cisco Network Modules Hardware Installation Guide and Cisco Interface Cards

Installation Guide.

Asynchronous Interface Numbering

For Cisco 3825 and Cisco 3845 routers, interface numbering for asynchronous interfaces is the same as for other interfaces. Use the interface number to specify the asynchronous line. For example, the command to configure port 1 of a 2-port asynchronous/synchronous WAN interface card in router HWIC slot 3 is interface serial 0/3/1. The command to configure the line associated with this port is line 0/3/1. Similarly, line 1/22 specifies the line associated with interface async 1/22 on a 32-port asynchronous network module in router slot 1.

Memory

Power

Memory

Cisco 3800 series routers contain the following types of memory:

• Main memory consists of ECC DDR SDRAM. It stores the running configuration and routing tables,

and buffers packets at the network interfaces. Both routers ship with 256 MB of main memory. The two DIMM slots can be upgraded with 128-MB, 256-MB, or 512-MB DIMMs to a maximum of 1024 MB (1 GB).

• An external CompactFlash memory card stores the Cisco IOS software image. The routers are

shipped with a 64-MB CompactFlash memory card, which can be upgraded to 128 MB or 256 MB.

• The routers boot from 4 MB of internal flash memory. This memory cannot be upgraded.

Tabl e 1 summarizes power options for Cisco 3800 series routers. Both the Cisco 3825 router and the

Cisco 3845 router support an AC input power supply, an AC input power supply with IP phone power output, or a DC input power supply. The Cisco 3825 router has one internal power supply and also provides a connector for the optional Cisco Redundant Power System (RPS) external backup power source. The Cisco 3845 router supports two internal power supplies and operates in redundant mode both are installed.

LED Indicators

LEDs can help you monitor your router’s performance and operation by providing power, activity, and status information. For an explanation of LED activity during power-up, see the “Verifying LED

Indications” section on page 34 of “Powering Up Cisco 3800 Series Routers.” To use LEDs for

troubleshooting, see Tab le 1 in “Troubleshooting Cisco 3800 Series Routers.”

For descriptions of LEDs on network modules or interface cards, see the Cisco Network Modules

Hardware Installation Guide and the Cisco Interface Cards Installation Guide.

Ventilation

Three internal multispeed fans cool the routers, controlled by a temperature sensor. At ambient temperatures below 40 degrees C, they operate at low speed to conserve power and reduce noise. At 40 degrees C or above they operate at high speed. The power supply has its own integrated fan.

Note On the Cisco 3825 router, when the router is installed with a Inline Power (ILP) power supply, the

internal multispeed fans will operate at high speed only. To verify the fan speed, use the show environment command.

Real-Time Clock and Battery

An internal real-time clock (RTC) with battery backup allows the routers to check the validity of the certification authority (CA) certificate. The RTC is accurate under the operating environmental conditions specified for the router.

The clock and battery are permanently installed. Under the specified operating environmental conditions, the battery lasts the life of the router and does not need to be replaced.
