Chassis Grounding
Chassis Grounding
Chassis grounding is provided through the power cable, which uses a standard grounding plug. The
chassis is also equipped with two 4 x 0.7 screw terminals for chassis grounding. The accessory kit
contains a crimp-type ground lug that attaches to the two screw terminals. For more information, see the
“Installing the Ground Connection” section on page 3-14 .

The Cisco IAD2430 series routers contain flash memory and main memory.
Onboard flash memory contains the Cisco IOS software image, boot flash contains the ROMMON boot

The default flash memory for the Cisco IAD2430 series IADs is 128 MB. Onboard CPU memory is
256 MB.
Port Numbering Conventions
Port numbering conventions for Cisco IAD2430, IAD2431, and IAD2432 series IADs are as follows:
• An external flash memory card is numbered CF 0.
• The 10/100BASE-T ports are numbered 10/100BASE-T 0/0 and 10/100BASE-T 0/1, from right to
left.
• The T1/E1 ports are numbered T1 1/0 or E1 1/0 and T1 1/1 or E1 1/1, from right to left.
• The slot for WICs and VICs is numbered slot 0. WIC and VIC interfaces are numbered by interface
with this slot number and an interface number, beginning with 0 and numbered from right to left.
• FXS voice port numbering begins at 2/0 and extends to 2/7, 2/15, or 2/23, depending on the number
of voice ports.
