EQUIREMENTS
To determine the memory size in your switch, use the following command:
show memory
For Summit switches running ExtremeWare 4.0 and above, the switch indicates the total
DRAM size in megabytes as part of the output. For Summit switches running previous
ExtremeWare releases, 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.

ONNECTIONS
The major difference between the models of the Summit switch is the port
configurations on each switch model. Summit switches use a combination of the
following types of ports:
•
1000BASE-SX ports using 850nm duplex SC connectors
•
1000BASE-LX ports using 1300nm duplex SC connectors
•
1000BASE-SX ports using MT-RJ connectors
•
Modular 1000BASE-SX and 1000BASE-LX using Gigabit Interface Connectors
(GBICs)
•
10BASE-T/100BASE-TX ports using RJ-45 connectors
•
100BASE-FX ports using 1300nm duplex SC connectors
•
100BASE-TX/1000BASE-T ports using RJ-45 connectors
Table 1-1 describes port configurations available on the different Summit switch models.
