Summit WM Technical Reference Guide, Software Version 5.386
● Two signal interfaces from redundant PSU that provide the following information to CPU (registered
and memory mapped):
● Provide alarm from PSU to s/w if redundant power module failed
● 2 MB of onboard Flash (used for system Bootrom, diagnostic, system serial number, Extreme
Networks-specific MAC address for Eth ports, etc…; accessible by s/w applications).
● Management ports:
● Main: 10/100BT LAN (RJ45) with Extreme Networks-specific MAC address, activity LED (bi-
color) and speed LED (bi- color).
● Console access port: RS-232 (DB9) serial interface
● CPU card will provide 7-segment LED display and 4 status LEDs (under s/w control) as a way to
visually communicate with service personnel and end users
● One Reset button (external)
NOTE
Replacing the NP4000 blade will alter the MAC address of the management interface, which affects the product
licensing system. As such, replacement of the NP4000 requires that the product key be transferred from the old
NP4000 card to the new one. This transfer should be arranged through Extreme Networks technical support or sales
support.

The SC1100 card has with the following main components:
● Network processor Unit
● 256MB of RDRAM
● 32MB of QDR SSRAM
● Non-transparent PCI bridge (Intel 21555) to provide 33/66MHz 32/64-bit PCI bus connectivity
between NPU PCI interface and cPCI backplane
● 12-port SPI4.2 Gigabit Mac
● 4 x front-accessible Gigabit (data) ports
