FAQ
What switch series is this expansion module compatible with?
The HPE J9987A is specifically designed for the HP 5400R zl2 Switch Series. It integrates directly into compatible chassis slots on these switches to add 24 Gigabit Ethernet ports with MACsec security. This compatibility ensures seamless operation and management through the switch's existing interface.
What type of security does the MACsec v3 implementation provide?
MACsec v3 provides hardware-accelerated encryption at the data link layer (Layer 2) of the network stack. It secures Ethernet frames between connected devices, protecting against eavesdropping, data tampering, and replay attacks. This security operates transparently to upper-layer protocols and applications while maintaining high performance.
What cabling and media does this module support?
The module supports standard twisted pair cabling (typically Cat5e, Cat6, or higher) through its 24 RJ-45 ports. It implements 1000Base-T network technology, which is designed specifically for Gigabit Ethernet over copper cabling. The ports auto-negotiate between 10, 100, and 1000 Mbps speeds based on connected equipment capabilities.
How does this expansion module benefit network performance?
The module provides Gigabit Ethernet connectivity with 1 Gbps maximum data transfer rate per port, which is up to 10 times faster than standard Fast Ethernet connections. This significantly reduces network bottlenecks for data-intensive applications. The full-duplex operation effectively doubles throughput, while the high port density consolidates connections efficiently within the switch chassis.
