Description of Hardware
Gigabit Uplink Module
The EM4601-SX-SC fiber optic module is designed for use in Accton switch models which have a single-port Gigabit Ethernet transceiver slot. At present, suitable units include the CheetahSwitch Workgroup-3628 (ES3628). Detailed information about configuring these modules and advice about Fast Ethernet configuration rules can be found in the switch’s user guide.
Warning: Before installing or removing the EM4601-SX-SC module, first disconnect the switch from the main power supply. For full safety instructions, please refer to the user guide that accompanies the switch.
Accton’s EM4601-SX-SC fiber optic module provides a Gigabit port which can be used for a high-speed backbone or server connection. It contains one 1000BASE-SX port that can be connected to a site up to 550 m (1805 ft) away with fiber cable.
Gigabit Port LEDs
Port status LEDs are also provided on the front of the module for “at-a-glance” network monitoring. The following table details the indicator functions provided by the module:
| | Extender Module LEDs |
LEDs | Condition | | Status |
