Fans and Filters

The S60 system comes from the factory with one Power Supply Unit (PSU) and one fan module installed

in the system

(Figure

5-1). If a second (redundant) PSU is installed and running, both the fan module and

the integrated fan/PSU are hot-swappable. With redundant PSUs, if you remove a fan module, traffic is

not interrupted.

WARNING: To run the system, both slots must have operating fan units. If a module is not installed in each

slot (either as part of the PSU or as an independent fan module), the system powers down when it exceeds an

internal temperature threshold.

WARNING: Dell Networking recommends replacing the fan tray within five minutes. If the fan tray is left out

for too long, the system may experience traffic disruption.

The S60 system supports two airflow direction options (normal and reverse). Do not mix fan airflow

types; you can only use a single airflow direction in a system. If the airflow directions are mismatched,

the system powers down in one minute.

• Normal—airflow is from the Input/Output (I/O) panel to the PSU

• Reverse—airflow is from the PSU to the I/O panel

Environmental factors can decrease the amount of time required between air filter replacements. Check

the environmental factors regularly. An increase in temperature and/or particulate matter in the air might

affect performance (for example, new equipment installation).

CAUTION: Check the fan air filters at six-month intervals and replace them as necessary. In order to

accurately determine air filter replacement intervals, regularly monitor the speeds of the cooling fans. An

increase in overall fan speed may indicate a clogged filter.

You must replace the S60 fan filters with new filters; you cannot clean and reuse the fan filters.

Replacement filters can be sourced online through third-party component suppliers. The fan filter is

manufactured by Qualtek Electronics Corporation and is stocked at several different online electronics

supply sites. The Qualtek part number is 09150-M/30 (on some sites the part number is referenced as

09150-M30), and provides conformance to the following standards as per the NEBS GR-63-CORE

specification:

• Minimum dust arrestance of 65%, per ASHRAE Standard 52.1-1992

• Minimum Efficiency Rating Value (MERV) of 2, per ANSI/ASHRAE Standard 52.2-2007

Dell Networking does not recommend any one site to procure these filters, but you can find a link on the

filter manufacturer's site (http://www.qualtekusa.com) that displays a list of distributors and their current

stock. Select Catalog > Fan_Accessories then scroll to part "09150-M/30*." Click the check mark in the

Distributor Stock Check column. A list of distributors and their reported inventory displays.

CAUTION: For Network Equipment Building System (NEBS)-compliance, use the NEBS-approved filters.

These filters are colored green and are installed exactly the same as the non-NEBS filters.
