LEDs that give you essential information at a glance.
The DES-5016 is a modular unit. The chassis has five slots. All the modules have LEDs.
See Chapter 4, LEDs, for information on interpreting the LEDs. All models come with
the CPU module in the top slot. The slots are in the following order: CPU module is
always on top. Slots one and two are full sized and come with either 8-Port 10/100-TX or
8-Port 100BASE-FX modules installed. Slots three and four are half-sized and only slot
three can accommodate optional modules. Slot four may not be used.
All ports can be used for network connections. The RS-232 port is used for Out of Band
