Maintaining the ONS 15454 M12 (ANSI and ETSI),
ONS 15454 M2 and ONS 15454 M6 Shelf
This chapter explains how to maintain the ONS 15454 (ANSI and ETSI), ONS 15454 M2 and ONS 15454
M6 shelf installations.
Unless otherwise specified, “ONS 15454” refers to both ANSI and ETSI M12 shelf assemblies.
Note
Due to memory limitations, TCC2/TCC2P cards are not supported as the node controller in multi-shelf
configuration from R10.5.2.6. Hence, it is recommended to use TCC3 card as the node controller in multi-shelf
configuration. However, the TCC2/TCC2P cards can be used as a subtended controller and also in a stand-alone
configuration.

NTP-G114 Inspect and Replace the Air Filter
This procedure ensures that the air filter is free from dirt and dust, which allows
optimum air flow and prevents dirt and dust from entering the shelf.

Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry
could constitute an energy hazard. Statement 206
Warning
The air filters are single-use only. They must not be cleaned and reused. This is a Telcordia NEBS requirement,
GR-63-CORE Issue 4.
Note
Air filters must be inspected every month. If they are dirty or clogged with dust, they must be replaced with
a new air filter.
Note
If you install the air filter below 15454E-CC-FTA or 15454-CC-FTA, only filters with part numbers
700-23193-01 and 700-23194-01 can be used in this configuration.
Note
Although the air filter can work with older fan trays if it is installed with either side facing up, it is recommended
that you install it with the metal bracing facing up to preserve the surface of the filter. You must install the
air filter with the metal bracing facing up with 15454E-CC-FTA or 15454-CC-FTA.
Caution
To install the air filter inside the air ramp unit (15454E-AIR-RAMP or 15454-AIR-RAMP), use the ETSI
version of the air filter (15454-FTF2 or 15454E-FTF4).
Note
Procedure
Step 1 If the air filter is installed in the external filter brackets, slide the filter out of the brackets while being careful
not to dislodge any dust that might have collected on the filter and proceed to Step 8. Figure 1: ANSI Shelf
Fan-Tray Air Filter in an External Filter Bracket (Front Door Removed), on page 3 shows the fan-tray air
filter in an external filter bracket on an ANSI shelf. Figure 2: ETSI Shelf Fan-Tray Air Filter in an External

an ETSI shelf.
Step 2 If the filter is installed below the fan tray and not in the external filter brackets, open the front door of the
shelf assembly. If the front door is already open, proceed to Step 3.
a) Open the front door lock.
The ONS 15454 comes with a pinned hex key for locking and unlocking the front door. Turn the key
counterclockwise to unlock the door and clockwise to lock it.
b) Press the door button to release the latch.
c) Swing the door open.
Step 3 (Optional) Remove the front door using the DLP-G10 Remove the Front Door. If you do not want to remove
the door or it is already removed, proceed to Step 4.

Step 4 Push the outer side of the handles on the fan-tray assembly to expose the handles.
Step 5 Pull the handles and slide the fan-tray assembly one half inch (12.7 mm) out of the shelf assembly and wait
until the fans stop.
Step 6 When the fans have stopped, pull the fan-tray assembly completely out of the shelf assembly.
Step 7 Gently remove the air filter from the shelf assembly. Be careful not to dislodge any dust that might have
collected on the filter.
Step 8 Visually inspect the air filter material for dirt and dust.
Step 9 Replace the air filter with a new one if the air filter is dirty or clogged with dust.
Do not leave the fan tray out of the chassis for an extended period of time because excessive heat
can damage the ONS 15454 cards.
Caution
Step 10 Replace the air filter:
a) If the air filter is installed in the external filter brackets, slide the new air filter all the way to the back of
the brackets.
b) If the filter is installed below the fan-tray assembly, slide the new air filter into the recessed compartment
at the bottom of the shelf assembly. Put the front edge of the air filter flush against the front edge of the
recessed compartment. Push the fan tray back into the shelf assembly.
If the fan tray does not slide all the way to the back of the shelf assembly, pull the fan tray out
and readjust the position of the air filter until the fan tray fits correctly.
Caution
On a powered-up ONS 15454, the fans start immediately after the fan-tray assembly is correctly
inserted.
Note
Step 11 To verify that the tray is plugged into the backplane, ensure that the LCD on the front of the fan-tray assembly
is activated and displays node information.
Step 12 Rotate the retractable handles back into their compartments.

NoneSecurity Level
The 15454-FTA3 fan-tray assembly can only be installed in ONS 15454 R3.1 and later shelf assemblies
(15454-SA-ANSI, P/N: 800-19857; 15454-SA-HD, P/N: 800-24848). The fan-tray assembly includes a pin
that prevents it from being installed in ONS 15454 shelf assemblies released before ONS 15454 R3.1
(15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1, P/N: 800-07149). Equipment damage can result
from attempting to install the 15454-FTA3 in a incompatible shelf assembly.
Caution
Do not force a fan-tray assembly into place. Doing so can damage the connectors on the fan tray and/or the
connectors on the backplane.
Caution
15454-CC-FTA (ANSI) is compatible with Software R2.2.2 and greater, and shelf assemblies 15454-SA-ANSI
and 15454-SA-HD. 15454E-CC-FTA (ETSI) is compatible with Software R4.0 and greater, and shelf assembly
15454-SA-ETSI.
Caution
As with the FTA3, the 15454E-CC-FTA and 15454-CC-FTA Fan Fail LED on the front of the fan-tray
assembly illuminates when one or more fans fail to indicate that a fan-tray assembly or AIP replacement is
required. But the Fan Fail LED on the 15454E-CC-FTA and 15454-CC-FTA will also illuminate when only
one power source is connected to the chassis, and or any fuse blows. In such conditions, the Fan Alarm is
triggered and the fans run at maximum speed.
Caution
To replace the fan-tray assembly, it is not necessary to move any of the cable management facilities.

Step 1 Review Table 1: Incompatibility Alarms for ONS 15454 ANSI , on page 17 (ANSI) or Table 2: Incompatibility
Alarms for ONS 15454 ETSI , on page 18 (ETSI) to ensure that you have compatible components when
