Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.

Memory and Software Upgrade Tasks
If you upgrade your Cisco IOS software to a later release, it may be necessary to increase the size of Flash memory.
For memory module installation instructions, see the applicable procedure as follows:
•
•
Figure 1 shows the physical locations of the replaceable memory components.
Figure 1 Memory Locations in Cisco IAD2420 Series IADs
Replacing System-Code Flash Memory
The system code (software) is stored on a Flash memory SIMM. It might be necessary to increase the system-code Flash memory if you are upgrading to software with more features.
The show version command allows you to see the amount of system-code Flash memory in KB. The following example shows a system with 8 MB of system-code Flash memory. The amount of system-code Flash memory (8192 KB) is shown on the next to last line of this example.

Cisco IAD2420 series IADs contain one Flash memory SIMM socket that holds a single 8-, 16-, or 32-MB Flash memory SIMM. Flash memory of 8, 16, or 32 MB may be required, depending on the size of the Cisco IOS software image.
To load two simultaneous images of software, at least 16 or 32 MB of Flash memory may be required, depending on the image size. To increase Flash memory capacity, you must remove the existing Flash memory SIMM and install a SIMM of the required capacity.
Note
Table 1 lists the available Flash memory SIMMs. Order system-code memory from Cisco Systems.

Step 7
If error messages relating to memory are displayed, repeat Step 2 through Step 7, taking care to seat the Flash memory SIMM firmly in its socket.
Step 8
Installing a Cisco IOS Image in Flash Memory
Follow this procedure to copy a Cisco IOS image from a TFTP server to the Cisco IAD2420 series IAD Flash memory if the Flash memory SIMM does not have an installed Cisco IOS image.
If your system already has a Cisco IOS image in Flash memory, follow the procedure in the "Copy an Image from a TFTP Server to a Flash Memory File System" section of the appropriate Configuration Fundamentals Configuration Guide, for Cisco IOS Release 12.1 or 12.2.
Step 1
If necessary turn the power ON. If there is no Cisco IOS image in the Flash memory, the system displays a boot fail message and then boots with a ROM monitor prompt (rommon 1>).
Step 2
Reboots the system to the boot helper image.
Step 3
Enters privileged EXEC mode.
Step 4
Copies the Cisco IOS image from a TFTP server to the system Flash memory.
Step 5
You will be prompted to enter the following information:
•
•
•
The Cisco IOS image is copied into Flash memory.
Step 6
(Optional) Verifies that the new Cisco IOS image (filename) is in the system Flash memory.
Step 7
(Optional) Enters global configuration mode, if you need to change the configuration register. Normally the default configuration register is used. See the show version output on page 7 to determine the existing configuration register.
Step 8
(Optional) Specifies a configuration register.
Step 9
(Optional) Exits from global configuration mode, if you changed the configuration register
Step 10
Reboots the system with the new Cisco IOS image.
Step 11
(Optional) Saves the configuration with the new configuration register. This message appears only if you entered global configuration mode in Step 7.
Step 12
(Optional) This message appears only if you have changed the configuration register. Press RETURN to confirm.
Step 13
Press RETURN to confirm the reboot.
Step 14
Press RETURN to bring up a router prompt.
Step 15
Procedure finished; system is running Cisco IOS software.
The following example copies a Cisco IOS image (c2400-a2i8sv5-mz) from a TFTP server to a 32-MB system Flash memory on a Cisco IAD2420 series IAD:
