SFP Transceivers
The SFP slots are hot-swappable, meaning that SFP transceivers can be installed or removed while the
switch is on. To install a transceiver:
1. Verify that the SFP module is the right type and form factor for the switch.
2. Slide the module completed into the slot, making sure that the module is properly seated against the
connector in the back of the slot
3. Install the fiber cable to connect to the network
4. Repeat the above steps for to install the second transceiver if required

Power On
The switch supports 100-240 VAC, 50-60 Hz power supply. The power supply will automatically convert
the local AC power source to DC power. After the switch is powered on, all LED indicators will light up
immediately and then all of them will turn off except for the power LED.
Boot Sequence
After the switch powers on, the bootloader will load the firmware into the memory. This process takes
about 30 seconds, after which all of the LEDs will flash once and the switch will then be operational.
2.2.1 Cabling Requirements
Cabling Requirements for Copper Ports
For Fast Ethernet connections, the grade of the cable must be at least Cat 5 with a maximum length of
100 meters.
For Gigabit Ethernet connections, the grade of the cable must be at least Cat 5e with a maximum length
of 100 meters.
Cabling Requirements for 1000SX/LX SFP Module
The length of cable supported depends on the types and quality of the transceiver and the cable. Cables
are broken up into two categories, multi-mode (MM) and single mode (SM). The latter is categorized into
several classes by the distance it supports. They are SX, LX, LHX, XD, and ZX. For the connector type,
they are mainly LC and BIDI LC. Combinations include:
• Gigabit Fiber with multi-mode LC SFP module
• Gigabit Fiber with single-mode LC SFP module
• Gigabit Fiber with BiDi LC 1310nm SFP module
• Gigabit Fiber with BiDi LC 1550nm SFP module
