GTL-2660 Version: 1
26-Port L2 Managed Gigabit Fiber Switch, 2 x 
10GbE SFP+, 4 x SFP/RJ45 Combo
The GTL-2660 is a 10 Gigabit fiber switch providing 24 Gigabit SFP ports, four Combo ports (RJ-45/SFP), 
as well as two 10 Gigabit SFP+ ports. 
This high-performance intelligent managed gigabit switch provides high capacity data transfer for high 
volume deployments such as data centers, government facilities and internet cafes. An expansion slot 
supports two 10 Gigabit SFP+ ports, with each RJ45 interface supporting adaptive positive and negative 
lines as well as auto MDI/MDI-X.
Key Features
IEEE 802.1d/w Spanning Tree Protocol (STP) and port mirroring
24 Gigabit SFP slots with 4 shared Gigabit Ethernet ports and 2 10-Gigabit slots
IEEE 802.3ad LACP for auto port aggregation
