Memory
The Cisco 812 ISR supports 512 MB DRAM and 512 MB compact flash memory. The Host router
software runs on the first core. The second core runs the WLAN Access Point software.
If WLAN is not supported in an SKU, all 512 MB DRAM memory is allocated to the first core. For the
SKUs that support WLAN, 128 MB out of the 512 MB main memory is allocated to the second core.
If WLAN is not supported in an SKU, all 512 MB DRAM compact flash memory is allocated to the first
core. For the SKUs that support WLAN, 64 MB out of the 512 MB main memory is allocated to the
second core.
Power Supply
The following are power adapters supported in the Cisco 812 ISR:
• AC Power Adapter, page 1-8
• PoE+ Splitter, page 1-8
AC Power Adapter
The default configuration is AC adapter that supports up to 4 A of 5 VDC current. The supported AC
power adapter is PWR2-20W-AC that has a nominal input voltage of 100 to 240 VAC.
PoE+ Splitter
The Cisco PoE+ splitter (C810-POE-SPL) splits PoE+ into power and GE. It has connectors built into
the power supply at both input and output so cables can be used at desired length as an option. Figure 1-4
shows the I/O side of the PoE+ splitter.
