The switch’s twisted-pair ports support MDI/MDI-X auto-crossover, so you can use either straight-through or
cross-pinned UTP cable.
Use Category 5 or 5e grade RJ-45 twisted-pair cable to connect up to 24 network devices (such as workstations
or servers) to the switch’s UTP ports.
Use 1310-
µ
m single-mode, or 1550-

m single-mode fiber optic cable to connect the fiber module to the
network.

The switch supports a 100–240-VAC, 50–60-Hz power supply. The power supply will automatically convert the
local AC power source to DC power. It doesn’t matter whether any devices are plugged into the switch or not
when you power on the switch (including modules). Once the power is on, all LEDs (except for the Power LED)
will light immediately and then turn off. The Power LED will remain on.
After resetting, the boot loader will load the firmware into memory. This takes approximately 30 seconds. After
that, all LEDs will flash once and the switch will automatically run a self-test.

For either a Fast Ethernet or Gigabit Ethernet twisted-pair network connection, use Category 5 or 5e cable
that’s 328 feet (100 m) long or shorter. We recommend Category 5e cable for Gigabit Ethernet networks.
