Here is a run down of stacking the switches.  Cat5e or Cat6 RJ-45 cables need to be used for stacking ports due to the throughput needed for traffic between stack units. Standard Cat5 may cause communication errors.  These steps should be performed one unit at a time until all stack members are powered up and their Stack IDs are selected. Performing the steps one unit at a time will allow for sufficient time to select the Stack ID for each unit. However, the entire stack should be cabled using the stacking ports before powering up the devices.  The unit ID selection process is as follows:   1. Power up the switch by applying AC power. When powering up, the configured LED number (corresponding to the previously saved unit ID) begins to flash. The LED flashes for 15 seconds. During this period, select a specific Stack ID by pressing the Stack ID button until the appropriate Stack ID LED is illuminated.   2. Selection Process - To advance the stacking ID LED number, continue pressing the Stack ID button. When LED 6 is flashing, pressing the Stack ID button results in the device being configured as a stand-alone. Pressing the Stack ID button again advances the Stack ID to 1. Unit 1 and Unit 2 are master-enabled units.   3. End selection process- The unit ID selection process is completed when the 15-second flashing period has transpired. The Stack ID button becomes unresponsive and the unit ID is set to the LED ID flashing at the end of the period.  Keep us updated, Thanks
HiiI'm setting up a test lab in office and found 2 PowerConnect switches (a 3524 & a 3548)I know it can do stacking through ports G3/G4 but i can't seem to get it to work..hope someone can enlighten me~Here's what i've done/tried:Connect straight network cable from port G3 of 3548 to port G4 of 3524. Reloaded the units.Assign address to 3548, login to console but under Stack Management, shows a single unit..Also LED infront (Stack ID) does not light up.Thought i might need to close the stacking loop?? so even tried to connect a cable from G4 of 3548 to G3 of 3524. But also doesn't work.Am i connecting them wrongly?Thanks much in advance!~
