OCX1100 Switches Hardware Overview

Juniper Networks OCX1100 Open Networking Switches are designed for large-scale cloud-based data centers, backed by the industry recognized Open Compute Project (OCP) Foundation. OCX1100 switches, which combine the cloud optimized OCP-based hardware design with the Juniper Networks Junos operating system (Junos OS), are high-density,top-of-rack,high-performance fixed-configuration switches for large-scale IP fabric deployments.

Software

Hardware

OCX1100 switches run Junos OS, which provides Layer 3 switching, routing, and security services. The same Junos OS code base that runs on OCX1100 switches also runs on all Juniper Networks EX Series, QFX Series, and OCX Series switches; M Series, MX Series, PTX Series, and T Series routers; and SRX Series Services Gateways. For information about installing software for your switch, see Junos OS Basics on the OCX Series.

The OCX1100-48SX is a top-of-rack switch that has 48 10-Gigabit Ethernet small form-factor pluggable plus transceiver (SFP+) ports and 6 built-in 40-Gigabit Ethernet quad small form-factor pluggable plus transceiver (QSFP+) ports. Each SFP+ port operatesasa 10-Gigabit Ethernet port and each QSFP+ port operates at native40-Gigabit speed. The OCX1100-48SX switch provides full duplex throughput of 1.44 Tbps.

Power Supplies

To provide carrier-class reliability, OCX1100-48SX switches include:

•

Two fully redundant, load-sharing power supplies (either AC or DC) that are hot-insertable and hot-removable field-replaceable units (FRUs).

•

Four redundant fan modules that are field-replaceable units.

•

Junos OS with its modular design that enables failed system processes to gracefully restart.

OCX1100 switches support AC or DC power supplies with different airflow directions, depending on the model. Power supplies for OCX1100 switches are fully redundant and load-sharing, and theyare hot-removable and hot-insertable FRUs. The OCX1100-48SX switches are shipped with two power supplies preinstalled in the rear panel of the switches.

Each power supply has a label—AIR IN (AFI) or AIR OUT (AFO)—on the faceplate of the power supply that indicates the direction of airflow. AIR IN (AFI) labels indicate back-to-front airflow while AIR OUT (AFO) labels indicate front-to-back airflow.

Power supplies are installed in the two power supply slots located on the rear panel of the switch.

Table 3 on page 5 lists the AC and DC power supplies used in OCX1100 switches and

the direction of airflow in them.

•

AC and DC power supplies in the same chassis.

•

•

Power supplies and fan modules with differentairflow labels (AIR IN (AFI) and AIR OUT (AFO)) in the same chassis.

The fan modules in OCX1100 switches are hot-insertable and hot-removable field-replaceable units (FRUs). OCX1100-48SX switches are shipped with four fan modules preinstalled in the rear panel of the switch.

The fan modules are available in two models that have different airflow directions—back-to-front airflow, indicated by the label AIR IN (AFI) and front-to-back airflow, indicated by the label AIR OUT (AFO). See “Cooling System and Airflow in an

OCX1100 Switches” on page 17.
