Overview

The HP J9536A is a 20-port Gigabit Ethernet PoE+ expansion module with two additional SFP+ slots, designed for HP's zl-series modular switch chassis. Each of the 20 RJ-45 ports delivers 1 Gbps connectivity with Power over Ethernet Plus (PoE+) capability, making it well-suited for deployments that include wireless access points, IP phones, security cameras, and other PoE-powered devices. The two SFP+ expansion slots support 10 Gigabit transceivers, providing high-speed uplink options for connecting to the network core or other switches.

As a zl-series module, the J9536A is built for HP's modular switching platforms such as the 5400 and 8200 series chassis. This modular approach allows network administrators to scale port counts and PoE capacity incrementally as needs grow. The key planning consideration is the chassis power supply — PoE+ can deliver up to 30 watts per port under IEEE 802.3at, so powering all 20 ports at full capacity requires a sufficiently provisioned power supply in the host chassis. SFP+ transceivers for the uplink slots are sold separately, giving administrators flexibility to choose the appropriate optic type for their cabling infrastructure.

Pros & Cons

👍 Pros

  • 20 Gigabit PoE+ ports in a single module provides substantial port density for network expansion.
  • Two SFP+ slots enable 10 Gigabit uplinks for high-bandwidth connectivity to the network backbone.
  • PoE+ support powers network devices directly through the Ethernet cable, reducing separate power infrastructure.
  • Hot-swappable zl module design allows installation without taking the entire switch chassis offline.

👎 Cons

  • Only compatible with HP zl-series switch chassis — cannot be used in non-HP or non-zl equipment.
  • PoE+ power delivery is limited by the chassis power supply budget, which may restrict how many ports can deliver full PoE+ wattage simultaneously.
  • SFP+ transceivers are not included and must be purchased separately.
  • The module's 1 Gbps port speed is a generation behind current 2.5/5/10G multi-gig standards.

Frequently Asked Questions

The J9536A is a zl-series module designed for HP zl-compatible switch chassis such as the HP 5400 and 8200 series. Verify your specific chassis model supports v2 zl modules before purchasing.
It provides 20 RJ-45 Gigabit Ethernet ports with PoE+ capability and 2 SFP+ expansion slots for high-speed uplinks.
Each of the 20 RJ-45 ports supports 1 Gbps (Gigabit Ethernet) data transfer rates.
Yes, all 20 RJ-45 ports support PoE+ (802.3at), which can power devices like access points, IP cameras, and VoIP phones directly through the Ethernet cable, subject to the chassis power budget.
The two SFP+ slots accept SFP+ transceivers for 10 Gigabit uplink connections, allowing high-bandwidth links to other switches or your network core.
