The Summit48si switch has two unpopulated ports that use Extreme mini-GBIC ports with LC 
connectors. You can use the following mini-GBICs in the Summit48si switch:

1000BASE-SX mini-GBIC

1000BASE-LX mini-GBIC

ZX mini-GBIC 

Use only Extreme Networks-certified mini-GBICs, available from Extreme Networks, into the 
mini-GBIC port in the switch.

For more information about the supported mini-GBIC types, see “Mini-GBIC Type and 
Hardware/Software Support” on page 23. For specifications of individual GBIC models, see 
“Mini-GBIC Specifications” on page 343.

Use the console port (9-pin, “D” type connector) for local management. This port allows you to attach a 
terminal and access the CLI via a serial connection. 

The Summit48si switch supports two hot-insert power supplies, either AC, shown in Figure 51, or DC, 
shown in Figure 52, with one power supply preinstalled at the factory. Extreme Networks recommends 
upgrading to ExtremeWare v7.1 or later to use the following features:

Use the 

show switch

 command to indicate the type of power supply (AC or DC) installed. 

A warning is printed if an AC and DC power supply are installed in the same switch. This is not a 
supported configuration.

An SNMP trap message is sent when the power supply is hot swapped.

You can remove or install Summit48si power supplies—one at a time—without interrupting operation. 
Each power supply has its own power socket, allowing you to connect independent power sources for 
each power supply. One functioning power supply must always be installed. Two power supplies 
operate in a load-sharing manner and increase the reliability of the switch.

You can use either DC or AC power supplies in the Summit48si, but you cannot install an AC and a DC 
power supply in the same switch. See Chapter 4 for information about removing and installing power 
supplies.
