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.
Power Supplies
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 they are 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.
