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.

Purpose

Maintaining the ONS 15454 M12 (ANSI and ETSI), ONS 15454 M2 and ONS 15454 M6 Shelf

As neededRequired/As Needed

OnsiteOnsite/Remote

NoneSecurity Level

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

Filter Bracket (Front Door Removed), on page 4 shows the fan-tray air filter in an external filter bracket on

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.
