Q
Which HP switches are compatible with the J9577A stacking module?
A
The J9577A module is compatible exclusively with HP 3800 series switches, requiring firmware version A.08.35 or later for full stacking functionality.
Q
How many switches can I stack with the HP 3800 4-port Stacking Module?
A
You can stack up to four HP 3800 switches in a single logical stack using the J9577A 4-port Stacking Module.
Q
What stacking bandwidth does the HP 3800 module provide?
A
Each port on the J9577A delivers up to 10 Gbps bidirectional stacking bandwidth, providing a total of 40 Gbps to aggregate switch traffic.
