Mounting NCM-1550-EM30
4.3.1
Mounting
the EM30 in the
Rack
Mounting the EM30 in the standard 19 inch equipment rack:
1.
Place the equipment in the rack.
2.
Use four screws fixed the mounting lug on the NCM-1550-EM30 front panel to
the rack.
3.
Reliably ground the equipment. The ground terminal is on the rear panel.
4.
Visually inspect each key (button) on the front panel to ensure that it is not trapped
under the edge of its hole. If a key is trapped, tap the key to enable it to move freely.
4.3.2
Connecting the RF Cables
Verify the RF input F connector type according to the ordering information, then
screw on the matched RF cable.
4.3.3
Connecting the Optical Fiber Cables
NCM-1550-EM30
has two output optical connectors.
1.
Verify the matched NCM-1550-EM30 fiber cable connector type according to the
ordering information.
2.
Verify that the fiber cable connector has been cleaned properly. If the fiber cable
connector needs to be cleaned, follow the cleaning procedure outlined in “Cleaning
Patch Cord or Pigtail Fiber Optical Connectors”.
3.
Verify that the NCM-1550-EM30 optical connector has not been exposed to any
contamination.
NOTE:
Any contamination of optical connector can significantly degrade
optical link performance. This degradation will most likely
manifest itself as poor signal-to-noise (SNR) performance.
4.
Note to butt the nick of the connectors and align them accordingly.
DANGER:
The fiber carries invisible laser radiation.
AVOID DIRECT
EXPOSURE TO BEAM
. Never operate the unit with a
broken fiber or with a fiber connector disconnected.
