6 MAINTENANCE
6-2
6.1 Maintenance and Checking
To use OD.RING modules under the optimum condition, check the items listed in Table 6-1.
Perform this check periodically (i.e., twice or more every year).
Table 6-1 Check Items
No. Item
Check
point
1 Appearance
of
module
Check that the module case is free from cracks, etc. If the case
is faulty, the internal circuit may have been damaged. This
damage can lead to a system malfunction.
2
LED
Check that the ERR LED of the OD.RING module is not on.
3 Looseness
of
mounting screws
Check module mounting screws for looseness. If the module
mounting screws are loose, tighten them. Loose screws can
cause a system malfunction and overheating.
4 Cable
covering
state
Check the cable covering state. An uncovered cable can cause a
system malfunction and electrical shock. It can also cause a fire
by shorting.
5
Dirt adhesion state
Check the module for dirt. If dirt is found, remove it with a
cleaner. Dirt adhesion to the module can cause the internal
circuit to short and start a fire.
6 Module
replacement
Replacing the module during hot swap may result in hardware or
software destruction. Be sure to turn off the power supply when
replacing the module.
7
Conditions of light
source and detector
surfaces of module
The light source and detector elements of the module are
protected by glass caps. If dust and dirt adheres to the glass
surface, optical transmission characteristics deteriorate.
For this reason, when the optical fiber cable is disconnected from
the module receptacle, be sure to cover the receptacle side of the
module and the optical connector side of the optical fiber cable
with the attached dust-proof cap. If dust and dirt adheres to the
glass surface due to frequent connection and disconnection of the
connector, blow it off with air or wipe it off lightly with a soft
cloth (e.g., gauze) dipped into ethyl alcohol. Do not use a cotton
swab, etc., because it may damage the glass surface. If dust and
dirt adheres to the end face of the optical fiber cable side, wipe it
off with a soft cloth dipped into ethyl alcohol.
