Summit “i” Series Switches
The Summit “i” series switches include the following models:
• Summit1i
• Summit5i
• Summit7i
• Summit48i
• Summit48si
Memory Requirements
The “i” series Summit switch must have 128MB of DRAM in order to support the features in
ExtremeWare version 6.0 or later.
To determine the memory size in your switch, use the following command:
show memory
For Summit switches running ExtremeWare 4.0 or later, the switch indicates the total DRAM size in
megabytes as part of the output. For Summit switches running ExtremeWare releases before 4.0, you
must calculate the memory by taking the sum of the bytes listed under
current free and adding to it
the bytes listed under
current alloc. If the sum is greater than 16,000,000, there is no need to upgrade
the memory on the switch. If this is not the case, please contact your supplier.
Port Connections
Summit “i” series switches use a combination of the following types of ports:
• Fixed ports
— 1000BASE-LX optical ports using LC connectors
— 1000BASE-SX optical ports using MT-RJ connectors

• Modular ports using GBICs
— 1000BASE-SX ports using 850 nm duplex SC connectors
— 1000BASE-LX ports using 1300 nm duplex SC connectors
— 1000BASE-LX70 ports using 1300 nm duplex LC connectors
— 1000BASE-ZX
— LX100
— UTP ports using RJ-45 connectors
• Modular ports using mini-GBICs:
