The article is a network module from manufacturer HPE, type CPNT, manufacturer's number J9988A, specifically developed for the 5400R ZL2 switch series. It is a 24-port module with 1-Gigabit-Ethernet SFP connections, used in switch systems to expand connection capacity. The modules are designed for use in professional network infrastructures where high port density and scalable network capacity are required.

Applications

The module is used in enterprise networks, particularly in environments requiring expansion of switch functionality through additional 1-Gigabit-Ethernet connections. It is suitable for applications such as LAN backbones, server access networks, or as an aggregation layer in larger network topologies. Integration into the 5400R ZL2 switch series enables a flexible network architecture, allowing the number of ports to be adjusted according to requirements.

Functions and Equipment in Detail

The module features 24 SFP connections, each supporting a data transfer rate of 1 Gigabit per second. The SFP ports allow connection to various transceiver modules, such as fiber optic or copper SFP modules, enabling network connections over different media. The use of SFP modules provides flexibility in selecting transmission media and range, depending on network requirements.

Technology Explained Simply

The term SFP" stands for Small Form-factor Pluggable, a standard interface for network modules used in switches and routers. The 1-Gigabit-Ethernet support means each port enables a maximum data rate of 1 Gbit/s, sufficient for data exchange between servers, workstations, or network devices. The module designation "v3 indicates the third generation of the module, specifically developed for the ZL2 series and possibly offering improved compatibility or performance characteristics compared to earlier versions.

Compatibility and Accessories

The module is exclusively intended for the HPE 5400R ZL2 switch series. It is not compatible with other switch models or series. Installation requires fitting into a corresponding switch chassis equipped with the necessary slots for such modules. Combination with SFP transceivers enables connection to various network devices via copper or fiber optic cables, where the choice of transceiver determines the range and medium.

Installation and Mounting

Installation is performed by inserting the module into the appropriate slot of the 5400R ZL2 switch. The modules are designed for hot-swap installation, meaning they can be inserted or replaced without powering down the switch. Physical mounting requires no additional tools; the module is simply pushed into the slot and locked. Configuration is carried out via the switch's network management software.

Operational Advantages

Using the module enables flexible scaling of the network port count without replacing the entire switch. The hot-swap capability reduces downtime during maintenance. Support for SFP transceivers provides flexibility in selecting transmission media, making the network infrastructure adaptable to various environments and requirements. Integration into the 5400R ZL2 series ensures consistent network management and control across the entire platform.
