•ISC port can be an individual port or a manual LACP trunk, but a dynamic LACP trunk can’t be configured as an ISC port.
•Maximum of 8 links in a DT trunk across two switches is supported with a maximum of 4 links per DT switch
•The current limitation of 60 manual trunks in a switch will now include DT manual trunks too.
•One ISC is supported per switch for a maximum of 60 DT trunks supported in the switch.
•Spanning Tree Protocol is disabled (i.e., PDUs are filtered) on DT ports.
An example of upstream traffic forwarding is as follows
Assuming the uplink connected to Switch B is blocked by STP and only an uplink in Switch A is active. Server 1 sent traffic with

LED status indicators for 5400zl series
The HP ProCurve Switch 5400zl series management module has various LED status indicators that are described in the following table.
LED | State | Indication |
Power | On (green) | The switch is receiving power. |
|
|

| Off | The normal state; indicates there are no fault conditions on the |
|
| switch. |
|
|
|
| Blinking | A fault has occurred on the switch, one of the switch modules, an |
| (orange) | individual port, a power supply, or a fan. The Status LED for the |
|
| module or other device with the fault will flash simultaneously. |
|
|
|
Test | On (green) | The switch |
|
| power cycled or reset the switch. The switch is not operational until |
|
| this LED goes off. The Self Test LED also comes on briefly when |
|
| you “hot swap” a module into the switch and the module is |
|
| automatically |
|
|
|
| Off | Normal operation; the switch is not undergoing |

|
|
| Blinking | A component of the switch has failed its |
| (orange) | for that component (for example, a switch module) and the switch |
|
| Fault LED will flash simultaneously. |
