Installing the ONS 15454 M12 (ANSI and ETSI) Shelf
The fan-tray assembly features an air filter at the bottom of the tray that you can install and remove by hand.
Remove and visually inspect this filter every 30 days and keep spare filters in stock. Refer to the "Maintain
the Node" chapter in the Cisco ONS 15454 DWDM Configuration Guide for information about cleaning and
maintaining the fan-tray air filter.
78 shows the position of the ONS 15454 ETSI fan-tray assembly. (The fan-tray assembly on the ONS 15454
ANSI is located in a similar position.)
Caution
Do not operate an ONS 15454 without the mandatory fan-tray air filter.
Caution
Fan-tray assembly 15454E-CC-FTA (ETSI shelf)/15454-CC-FTA (ANSI shelf) is required when any of the
following cards are used in an ONS 15454 DWDM application: ADM-10G, GE_XP, 10GE_XP, GE_XPE,
10GE_XPE, ML-MR-10, and CE-MR-10.
Caution The 15454-FTA3-T fan-tray assembly can only be installed in ONS 15454 Release 3.1 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 Release 3.1
(15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1). Equipment damage can result from attempting
to install the 15454-FTA3 in an incompatible shelf.
Note
15454-CC-FTA is compatible with Software Release 2.2.2 and greater and shelf assemblies 15454-SA-HD
and 15454-SA-ANSI. 15454E-CC-FTA is compatible with Software Release 4.0 and greater and shelf
15454-SA-ETSI.
Note Fan-tray assembly 15454E-CC-FTA (ETSI shelf)/15454-CC-FTA (ANSI shelf) is required when the 80-WXC-C
card is placed near MXP or TXP units.
