9.5.2. Connecting to a Hub
The SDA-4S models and SDA-4H can be connected to another hub (for example,
for daisy chaining). The ports of the SDA-4S models support MDI/MDI-X
automatic crossover, allowing connection of straight-through or crossover cables.
However, for the SDA-4H model, only the left-most RJ-45 port (J5) is a crossover
port (see Figure 9-7).
The SDA-4S and SDA-4H cable configurations for connectivity to a hub, are as
follows:
! Connector: 8-Pin RJ-45
! Cable:
! SDA-4H: crossover-cable
! SDA-4S models: straight-through or crossover cables (due to MDI/MDI-X
ports)
! Connector pinouts: SDA-4H:

To connect SDA-4S or SDA-4H to a hub:
1. Connect the RJ-45 male, at one end of the cable, to the SDA-4H’s left-most RJ-
45 port (J5), or any SDA-4S’s RJ-45 port.
2. Connect the RJ-45 male, at the other end of the cable, to the hub.
