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.

Chapter 3: Cooling System and Airflow

Do Not Install AIR IN (AFI) and AIR OUT (AFO) Components in the Same Chassis

Do not install power supplies and fan modules with different airflow labels (AIR IN (AFI) and AIR OUT (AFO)) in the same chassis. If the fan modules have AIR IN (AFI) labels, the powersupplies must also have AIR IN (AFI) labels; if the fan modules have AIR OUT (AFO) labels, the power supplies must also have AIR OUT (AFO) labels.

The labels on the power supplies and fan modules should match the labels on the switch chassis.

Mixing components with AIR IN (AFI) and AIR OUT (AFO) labels in the same chassis hampers the performance of the cooling system of the switch and leads to overheating of the chassis.

Under normal operating conditions, the fan modules operate at a moderate speed. Temperature sensors in the chassis monitor the temperature within the chassis.

CAUTION: The system raises an alarm if a fan module fails or if the ambient

temperature inside the chassis rises above the acceptable range. If the temperature inside the chassis rises above the threshold temperature, the system shuts down automatically.

Cabinet airflow requirements

When you mount the device in a cabinet, ensure that ventilation through the cabinet is sufficient to prevent overheating.

•

Ensure adequate cool air supply to dissipate the thermal output of the device or devices.

•

Ensure that the hot air exhaust of the chassis exits the cabinet without recirculating into the device. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top ensures the best airflow through the chassis. If the cabinet contains a top or doors, perforations in these elements assist with removing the hot air exhaust.

•

Install the device in the cabinet in a way that maximizes the open space on the side of the chassis that has the hot air exhaust.

•

Route and dress all cables to minimize the blockage of airflow to and from the chassis.

•

Ensure that the spacing of rails and adjacent cabinets is such that there is proper clearance around the device and cabinet.

•

A cabinet larger than the minimum required provides better airflow and reduces the chance of overheating.

Installing an AC Power Supply in an OCX1100 Switch

The AC power supply in OCX1100 switches is a hot-removable and hot-insertable field-replaceable unit (FRU) installed in the rear panel of the switch: You can remove and replace it without powering off the switch or disrupting switch functions.

CAUTION: Do not install:

•

AC and DC power supplies in the same chassis.

•

AC power supplies in DC switch models or DC power supplies in AC switch models.

•

Power supplies with different airflow labels (AIR IN (AFI) and AIR OUT

(AFO)) in the same chassis.

•

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

Before you install an AC power supply in the switch:

•

Ensure you understand how to prevent electrostatic discharge (ESD) damage. See

“Prevention of Electrostatic Discharge Damage” on page 167.

Ensure that you have the following parts and tools available to install the power supply:

•

ESD grounding strap

•

Phillips (+) screwdriver

Page 98

OCX1100 Switch Hardware Guide

NOTE: Each power supply must be connected to a dedicated power source

outlet.

To install an AC power supply in the switch:

1. Ensure that you have the correct power supply. The label AIR IN (AFI) or AIR OUT

(AFO) on the power supply must match the label AIR IN (AFI) or AIR OUT (AFO) on

the installed fan module.

2. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD

point on the chassis.

3. If the power supply slot has a cover panel on it,loosen the captive screws on the cover

panel by using your fingers or a screwdriver. Hold the captive screw and gently pull it outward to remove the cover panel. Save the cover panel for later use.

4. Taking care not to touch power supply pins, leads, or solder connections, remove the

power supply from the bag.

5. Using both hands, place the power supply in the power supply slot on the rear panel

of the switch and slide it in until it is fully seated and the clip clicks into place. See

Figure 24 on page 78.
