HP ProCurve zl 24p Mini-GBIC (J8706A) is a module that adds 24 SFP ports to a ProCurve Switch zl, providing a bank of pluggable interfaces for network connections. It is intended for a switch chassis with the zl module format.
The ports accept Small Form-factor Pluggable transceivers. The module’s ports do not support Power over Ethernet (PoE), so they provide network connectivity without PoE power delivery.
For a ProCurve Switch 5400zl, HP specifies software release K.11.32 or later for this module. This identifies the documented software requirement for that switch series.
