Introduction to HPE Procurve X121 Transceiver

J4858-69201 is the part number for a HPE Procurve X121 1 Gbps Gigabit Ethernet Full-Duplex Transceiver. It is a small form-factor pluggable (SFP) module that can be used with a variety of HPE switches and routers to provide high-speed network connectivity.

The X121 transceiver supports full-duplex Gigabit Ethernet communication over a single fiber optic cable or copper cable, with a transmission distance of up to 10 kilometers (6.2 miles) over fiber and up to 100 meters (328 feet) over copper. It operates at a wavelength of 1310 nanometers and uses a duplex LC connector for fiber connections and an RJ-45 connector for copper connections.

The X121 transceiver is hot-swappable, meaning it can be inserted or removed from a switch or router without disrupting the rest of the network. It also supports digital diagnostic monitoring (DDM), which allows network administrators to monitor and troubleshoot the performance of the transceiver.

Features and Benefits

J4858-69201 is an HPE Procurve X121 1 Gbps Gigabit Ethernet Full-Duplex Transceiver, which is a small form-factor pluggable (SFP) transceiver designed for use in HPE Procurve switches and routers. It is used to connect network devices such as switches, routers, and servers to a network, and is capable of transmitting and receiving data at speeds of up to 1 Gbps over a fiber optic cable.

Some of the features and benefits of the J4858-69201 transceiver are:

  • Small Form-Factor Pluggable (SFP) Design: The J4858-69201 transceiver has a small form-factor pluggable design, which means it is easily replaceable and can be hot-swapped without powering down the device. This makes it easy to add or remove transceivers as needed, without disrupting network connectivity.
  • 1 Gbps Data Transfer Speed: The J4858-69201 transceiver is capable of transmitting and receiving data at speeds of up to 1 Gbps, which is ideal for high-speed data transfer between network devices.
  • Full-Duplex Transmission: The J4858-69201 transceiver supports full-duplex transmission, which means it can transmit and receive data simultaneously, reducing network congestion and improving overall network performance.
  • Gigabit Ethernet Connectivity: The J4858-69201 transceiver provides Gigabit Ethernet connectivity, which is the standard for high-speed networking.
  • Multi-Mode Fiber Support: The J4858-69201 transceiver supports multi-mode fiber optic cables, which can transmit data over short distances (up to 550 meters).
  • Digital Optical Monitoring (DOM): The J4858-69201 transceiver supports digital optical monitoring (DOM), which provides real-time monitoring of the transceiver's operating conditions, including temperature, voltage, and optical power levels. This helps to ensure that the transceiver is functioning properly and can help identify potential issues before they cause problems.

Installation and Configuration

J4858-69201 is a small form-factor pluggable (SFP) transceiver module designed for use with HPE Procurve switches. This transceiver supports 1 Gigabit Ethernet connectivity and operates in full-duplex mode.

To install and configure the J4858-69201 transceiver module, follow the steps below:

  • Power off the HPE Procurve switch.
  • Locate the SFP module slot on the switch.
  • Remove the protective dust cover from the slot.
  • Insert the J4858-69201 transceiver module into the slot. Ensure that it is inserted correctly and securely.
  • Connect a network cable to the RJ-45 port on the transceiver module.
  • Power on the switch.
  • Verify that the switch recognizes the transceiver module by running the "show interfaces transceiver" command in the switch's command-line interface (CLI).
  • Configure the transceiver module using the switch's CLI or web-based management interface. This may include setting the speed and duplex mode, as well as configuring VLANs, QoS, and other network settings.
  • Test the connectivity of the network by sending and receiving data.
