Page 11: Ex2300 System Overview
Juniper Networks EX Series Ethernet Switches provide scalable connectivity for the enterprise market, including branch offices, campus locations, and data centers. The Juniper Networks EX2300 Ethernet Switches run the Juniper Networks Junos operating system (Junos OS), which provides Layer 2 and Layer 3 switching, routing, and security services.
Page 12 Support for Juniper Networks Junos Fusion Enterprise—EX2300 switches can act as a satellite device to support a Juniper Networks Junos Fusion Enterprise deployment, which can combine several wiring closets into one logical management platform.
Page 13 NOTE: You cannot form a Virtual Chassis by using SFP transceivers. For forming a Virtual Chassis, you must explicitly configure an uplink port on each of the switches to be connected as a VCP. See Setting an Uplink Port on an EX Series or QFX Series Switch as a Virtual Chassis Port.
Page 14 NOTE: IEEE 802.3at class 4 powered devices require category 5 or higher Ethernet cables. The remainder of this topic uses the term PoE to refer to both PoE and PoE+ unless there is a need to distinguish between the two.

CAUTION: If you face a problem running a Juniper Networks device that uses a third- party optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem.
Page 87 Cable Specifications EX Series switches support SFP+ passive DAC cables. The passive Twinax cable is a straight cable with no active electronic components. EX Series switches support 1 m, 3 m, 5 m, and 7 m long SFP+ passive DAC cables.

Page 89 mode loss (HOL) occurs. Together, these factors reduce the transmission distance of multimode fiber compared to that of single-mode fiber. Single-mode fiber is so small in diameter that rays of light reflect internally through one layer only. Interfaces with single-mode optics use lasers as light sources. Lasers generate a single wavelength of light, which travels in a straight line through the single-mode fiber.
Page 90: Calculating The Fiber-Optic Cable Power Budget For Ex Series Devices
Calculating the Fiber-Optic Cable Power Budget for EX Series Devices To ensure that fiber-optic connections have sufficient power for correct operation, calculate the link's power budget when planning fiber-optic cable layout and distances to ensure that fiber-optic connections have sufficient power for correct operation. The power budget is the maximum amount of power the link can transmit.

Ensure that you have a rubber safety cap available to cover the transceiver. The transceivers for Juniper Networks devices are hot-removable and hot-insertable field-replaceable units (FRUs): You can remove and replace them without powering off the device or disrupting the device functions.
Page 161 NOTE: We recommend that you use only optical transceivers and optical connectors purchased from Juniper Networks with your Juniper Networks device. CAUTION: If you face a problem running a Juniper Networks device that uses a third- party optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem.
Page 162 CAUTION: Before you slide the transceiver into the port, ensure that the transceiver is aligned correctly. Misalignment might cause the pins to bend, making the transceiver unusable. 6. Slide the transceiver in gently until it is fully seated. If you are installing a CFP transceiver, tighten the captive screws on the transceiver by using your fingers.
