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.Cisco 1800 series
fixed-configuration routers contain 128 MB of internal DRAM memory by default. Cisco 1800
series fixed-configuration router models also contain a single 200-pin DDR Small Outline DIMM
(SODIMM) slot that can accommodate up to a 256-MB SODIMM, for a maximum of 384 MB of
internal DRAM memory.
NVRAM—Internal flash memory. Stores the bootstrap program (ROM monitor), the configuration
register, and the startup configuration. All Cisco 1800 series fixed-configuration models contain 2
MB of boot/NVRAM memory by default.
Flash memory—External CompactFlash memory. Stores the operating system software image. All
Cisco 1800 series fixed-configuration models contain 32 MB of internal flash memory by default,
and can use external CompactFlash cards up to 128 MB in capacity.

Description
The router has successfully booted up, and the software is functional. This LED blinks while
booting or while in the ROM monitor mode.
This LED shows wireless access point link status. It is active only on wireless models.

Blinking green indicates that no client is associated.
Green indicates that the inline power supply is present.
Amber indicates a fault with the inline power supply.
Off indicates that the inline power supply is not installed.
These LEDs indicate Fast Ethernet port link and status for both FE WAN ports (ports 0 and 1
on the Cisco 1811 and Cisco 1812 routers; port 0 on the Cisco 1801, Cisco 1802, and
Cisco 1803 routers) and the FE switch ports (ports 2 through 9 on the Cisco 1811 and
Cisco 1812 routers; ports 1 through 8 on the Cisco 1801, Cisco 1802, and Cisco 1803routers).
Green indicates a successful FE link.
Off indicates no link.
