Figure 5-6 Connecting the Router to the AC Receptacle

Step 6 Press the power switch on (-). (See Figure 5-7.)

Figure 5-7 Power Switch in the On (—) Position


Connecting the DC Power Supply


Note The minimum wire gauge size supported on the DC dual power supply is 17 American Wire Gauge (AWG), which has a 1.5mm wire diameter. The maximum wire gauge size supported on the DC dual power supply is 10 AWG, which has a 6mm wire diameter.


To connect the DC power supply, perform the following steps:


Step 1 Ensure that the -48V and +48V leads are disconnected from the power source.

Step 2 Attach an ESD-preventive wrist strap to your wrist, and to the router or to a bare metal surface. (See the "Preventing Electrostatic Discharge" section on page 2-3.)

Step 3 Using a wire stripper, strip approximately 0.55 inch (14 mm) from the -48V, +48V, and ground leads. (See Figure 5-8 and Figure 5-9.)

Figure 5-8 Stripping the DC-Input Leads

Figure 5-9 DC Lead Stripped 0.55 inch (14 mm)

Step 4 Confirm that the power switch located on the front of the power supply is in the off position (O). (See Figure 5-10.)

Figure 5-10 Power Switch in the Off (O) Position

Step 5 Locate the ground, positive, and negative terminals. (See Figure 5-10.)


Caution Leave a small service loop in the ground lead. If a strain is placed on the ground, the +48V, or the -48V DC input leads causing them to pull out of the power supply, the ground power lead must be the last to disconnect from the power supply terminal.

Step 6 Insert the stripped end of the ground lead all the way into the ground lead receptacle. Tighten the receptacle screw using a 1/8-inch flat blade screwdriver. (See Figure 5-11.)


Note Make sure the entire stripped end of each lead is inserted all the way into its receptacle. If any exposed wire at the stripped end of a lead is visible after inserting the lead into its receptacle, remove the lead from the receptacle, use the wire stripper to cut the stripped end of the lead, and repeat Step 2 through Step 6.

Step 10 If the module appears misaligned, carefully remove it and reseat it, ensuring that the release lever is flush against the side of the RP memory socket.


Checking the 512-MB Route Processor Installation

When you power up the router, the router reinitializes and detects the memory change as part of the reinitialization cycle. The time required for the router to initialize can vary with different router configurations and memory configurations.

If the router does not initialize properly after you replace the memory, or if the console terminal displays a checksum or memory error, verify that you have installed the correct RP memory and that it is installed correctly in the router.

If the router fails to restart properly after several attempts and you are unable to resolve the problem, access Cisco.com or contact your Cisco service representative for assistance. Before calling, make note of any console error messages, unusual LED states, or other router indications or behaviors that might help to resolve the problem. Under certain highly improbable scenarios (for example, battery failure), the router may fail to boot after the 512-MB upgrade. In such cases, see the "Obtaining Technical Assistance" section on page xxii for information on contacting Cisco.

To check the installation of the RP memory, use the show version command and check that the upgraded RP memory is 512 MB.

See the following show version command example to locate the RP memory. Line 17 of the example is in italic print to indicate where the RP memory is listed.
