Note: The Cisco 3945 router supports two memory slots which has been installed two 512MB memory cards. When upgrading the memory, the same capacity of memory cards must be inserted into the two memory slots in the same time. It doesn't support to use only a single memory slot. Note To install double-wide service modules in the Cisco 3900 series routers, remove the slot divider between slots SM3 and SM4 (3945) and remove the blank panel to the right of SM2 (3925).

Hi, Is it possible to configure 64 FXO ports on a Cisco 3945? It has been told in UC8.0 launch but I can only configure 48, 16 on the HWIC slots and 32 on the NM slot using four NM-HD-2V. C3900-SPE150/K9 is the Cisco Services Performance Engine 150 for Cisco 3945 ISR. The Cisco 3900 Series offers field-replaceable Cisco Services Performance Engine (SPE). These SPEs allow you to protect your initial investment in the Cisco 3900 platform for a longer time period and scale router performance as your network and branch-office needs.
