Air Filter; Ntp-G8 Install The Fan-Tray Assembly - Cisco ONS 15454 Hardware Installation Manual

Air Filter

Air Filter
The ONS 15454 contains a reusable air filter (for ANSI: 15454-FTF2; for ETSI: 15454E-ETSI-FTF) that is
installed either below the fan-tray assembly or, for the ONS 15454 ANSI, in the optional external filter
brackets.
The reusable filter is made of a gray, open-cell, polyurethane foam that is specially coated to provide fire and
fungi resistance. All versions of the ONS 15454 can use the reusable air filter. Spare filters should be kept in
stock. Inspect the air filter every 30 days, and clean the filter every three to six months. Replace the air filter
every two to three years. Avoid cleaning the air filter with harsh cleaning agents or solvents.
Earlier versions of the ONS 15454 ANSI shelf used a disposable air filter that is installed beneath the fan-tray
assembly only. However, the reusable air filter is backward compatible.

Caution
Do not operate an ONS 15454 without a fan-tray air filter. A fan-tray air filter is mandatory, except for ONS
15454 ANSI applications in an outside plant cabinet.
Caution
You must place the edge of the air filter flush against the front of the fan-tray assembly compartment when
installing the fan-tray on top of the filter. Failure to do so could result in damage to the filter, the fan-tray, or
both.
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 back panel of the shelf.
