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.

Before you begin the fan replacement procedure, disconnect the power and remove the cover, as described in the replacement procedure, install the chassis cover as described in the “Installing the Chassis Cover”

section on page 13.

Safety Warnings

Warning

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.

Removing the Chassis Cover

Warning

Do not work on the system or connect or disconnect cables during periods of lightning activity.

Statement 1001

Read the installation instructions before connecting the system to the power source.

Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first.

Removing the Chassis Cover

Cisco 2811 series routers have a cover that lifts off after you slide it free from front panel.

Statement 1004

Statement 43

Statement 1026

Caution

Do not, under any circumstances, tamper with or attempt to remove the safety shields protecting the WIC/HWIC slots and connectors on the Cisco 2811 routers.

Removing the Cover from Cisco 2811 Routers

To remove the chassis cover for a Cisco 2811 series router, follow these steps. You will need a number 2 Phillips screwdriver and a flat-blade screwdriver with a blade width of 1/4 ± 1/32 inch (5 to 7 mm). Rack-mounted routers must be removed from the rack and positioned on a flat surface before you start removing the cover.

Caution

Warning

To prevent damage to the chassis, follow this procedure to remove the cover. Do not pry on the plastic bezel or on the ears at either side of the chassis on the back.

The following warning applies only if the router is provided with a DC power input:

Before performing any of the following procedures, ensure that power is removed from the DC circuit.

Step 1

Warning

Step 2 Step 3 Step 4

Caution

Make sure that the router is turned off and disconnected from its power source.

Before opening the unit, disconnect the telephone-network cables to avoid contact with telephone-network voltages.

Statement 1041

If rack-mounting brackets are attached to the chassis, remove them, using a Phillips screwdriver.

Remove the four screws at the back of the top cover, using a Phillips screwdriver.

Perform the following steps to loosen the cover from the chassis:

Insert the blade of the 1/4-inch screwdriver straight into the square hole on either side of the chassis near the back, so that it fits against the chassis and does not go past the chassis and into the narrow slot. See

Figure 1.

Make sure that the tip of the screwdriver does not slide into the narrow vertical slot that is visible inside the square hole. The tip of the screwdriver should rest on the metal tab just inside the chassis cover and to the right of the vertical slot.

Figure 1 Inserting the Screwdriver into the Side of the Chassis

With the screwdriver positioned as required in Step a. above, rotate the screwdriver a quarter turn toward the back of the chassis to loosen one side of the cover. See Figure 2.

Caution

The friction fit may be fairly tight; however, if the cover does not move with moderate effort, make sure that the screwdriver is not inserted into the narrow vertical slot.

Figure 2 Rotating the Screwdriver to Loosen the Chassis Cover

Repeat Step a. and Step b. for the opposite side of the chassis.

Step 6

Note

After the cover is loosened as in Step 4, there may still be some friction to overcome as you complete the removal. However, do not use the screwdriver again as in Step 4.

Lift the cover free of the router chassis.

Caution

Before you remove or install a fan, remove the chassis cover as described in the “Removing the Chassis

Cover” section on page 2.

When you remove or install a fan, always wear an ESD-preventive wrist strap, and ensure that it makes good contact with your skin. Connect the equipment end of the wrist strap to the metal part of the chassis.
