the empty power supply slot. Press until the supply is completely in the slot, so
that the connectors on the back of the supply are fully engaged with the pins
on the power backplane.
Attention: Make sure you insert the power supply right-side up. It is possible
to insert the supply upside down, although the supply will not engage with the
power backplane when upside down. The power supply is right-side up when
the power connector is on the left and the fan vent is on the right. All
references to right-side and left-side are referenced from looking at the device
from the front.
5. Secure the two screws near the edges of the supply to lock the supply in place.
6. Connect the power cord to the power supply.
7.
Connect the plug end of the power cord into an outlet.
CAUTION:
For the NEBS compliant installation of c-series switches with AC system use
a ground wire of at least 8 American Wire Gauge (AWG). The ground wire
should have an agency-approved crimped connector (provided with the
chassis) attached to one end, with the other end attached to building ground.
The connector must be crimped with the proper tool, allowing it to be
connected to both ground screws on the enclosure. Before crimping the
ground wire into the provided ground lug, insure the bare copper wire has
been cleaned and antioxidant is applied to the bare wire.
Installing the device
You can install the system on a desktop, or in an open-air, Telco rack.
Desktop installation
1. Set the device on a flat desktop, table, or shelf. Make sure that adequate
ventilation is provided for the system; a 3-inch clearance is recommended on
each side.
2. Go to “Powering on the system” on page 21.
Rack mount installation
For rack mount installations, you should use an open-air Telco equipment rack.
Each unit ships with rack ears attached to the front of the unit. You can mount the
rack ears in 4 different locations on the device.
Note: When attaching the chassis to the rack, use star washers to provide
grounding of the chassis to the rack. If any single-hole grounding lugs are
used, star washers must be used to prevent rotation of the lug.
Forward rack mount position
The c-series switches ship with the rack ears attached to the front of the device as
shown in figure Figure 11 on page 17. Alternative mounting positions for the rack
mount ears are shown in figures Figure 12 on page 18, Figure 13 on page 19 and
Figure 14 on page 20.
