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.
OL-5808-01
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.

Overview of Cisco 2800 Series Routers
The Cisco 2800 series of integrated services routers offers secure, wire-speed delivery of concurrent
data, voice, and video services. The modular design of the Cisco 2800 series routers provides maximum
flexibility, allowing you to configure your router to meet evolving needs. The Cisco 2800 series routers
incorporate data, security, and voice services in a single system for fast, scalable delivery of crucial
business applications. The routers offer features such as hardware-based VPN encryption acceleration,
intrusion-protection and firewall functions, and optional integrated call processing and voice mail. The
routers offer a wide variety of network modules and interfaces, voice digital signal processor (DSP)
slots, high-density interfaces for a wide range of connectivity requirements, and sufficient performance
and slot density for future network expansion requirements and advanced applications.
The Cisco 2800 series consists of four versions. The Cisco 2801 routers and Cisco 2811 routers are one
rack unit in height and have two 10/100 LAN ports. The more powerful Cisco 2821 routers and
Cisco 2851 routers are two rack units in height and have two 10/100/1000 LAN ports. The higher-end
router platforms of the Cisco 2800 series offer increased performance, increased slot density including
network module slots ad extension voice module slots and increased inline power output.
Figure 1, Figure 2, and Figure 3 show front views of the Cisco 2800 series routers.

Cisco Product Identification Tool
The Cisco Product Identification (CPI) tool provides detailed illustrations and descriptions showing
where to locate serial number labels on Cisco products. It includes the following features:
• A search option that allows browsing for models using a tree-structured product hierarchy
• A search field on the final results page making it easier to look up multiple products
• End-of-sale products are clearly identified in results lists
The tool streamlines the process of locating serial number labels and identifying products. Serial number
information expedites the entitlement process and is important for access to support services.

Cisco 2821, and Cisco 2851 routers; they can be removed and installed without opening the chassis.
Advanced integration modules (AIMs), expansion DRAM memory modules (DIMMs), and packet voice
data modules (PVDMs) plug into connectors inside the chassis; they can be removed and installed only
by opening the chassis.

Hardware Features
Memory
Cisco 2800 series routers contain the following types of memory:
• DRAM—Stores the running configuration and routing tables and is used for packet buffering by the
network interfaces. Cisco IOS software executes from DRAM memory.
• Boot/NVRAM—Internal flash memory. Stores the bootstrap program (ROM monitor), the
configuration register, and the startup configuration.
• Flash memory—External flash memory. Stores the operating system software image.
Table 3 summarizes the memory options for Cisco 2800 series routers. The default memory numbers for
RAM represent the minimum usable memory. You can install additional RAM in multiples of the default
amount, up to the maximum amount.

to increase memory to the maximum of 384 MB.
2. Cisco 2811 routers can accept one 256 MB and one 512 MB DIMM to provide 768 MB of usable memory.
3. Cisco 2851 routers can accept two 512 MB DIMMs to provide 1024 MB of usable memory.

Power
Table 4 summarizes the power options for Cisco 2800 series routers. Cisco 2801 routers are equipped
for operation using AC power only. Cisco 2811, Cisco 2821, and Cisco 2851 routers can be equipped for
operation using either AC or DC input power by installation of the appropriate chassis power supply. IP
phone power is supported if the appropriate AC-input chassis power supply is installed.

Chassis Ventilation
Internal multispeed fans provide chassis cooling, controlled by an onboard temperature sensor.
The Cisco 2801 router has two fans. The Cisco 2801 router with inline power includes two additional
fans integrated with the inline power supply, for a total of four fans. The Cisco 2801 internal fans operate
at three different speeds, running at the slower speeds to conserve power and reduce fan noise at ambient
temperatures below 40
The Cisco 2811 router has three fans that operate at a slower speed to conserve power and reduce fan

Real-Time Clock
An internal real-time clock with battery backup provides the system software with time of day on system
power up. This allows the system to verify the validity of the certification authority (CA) certificate. In
the Cisco 2811, Cisco 2821, and Cisco 2851 routers, the clock and battery are permanently installed; the
battery lasts the life of the router under the operating environmental conditions specified for the router.
The Cisco 2801 router has a socketed lithium battery. This battery lasts the life of the router under the
operating environmental conditions specified for the router, and is not field-replaceable.

NoteIf the lithium battery in a Cisco 2801 router should fail, the router must be returned to Cisco for repair.
Although the battery is not intended to be field-replaceable, the following warning must be heeded:
Warning
There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with
the same or equivalent type recommended by the manufacturer. Dispose of used batteries according
to the manufacturer’s instructions.
