Replacing Air Filters on J2350 Routers
The cooling fans on J2350 routers draw air through vents along the left side of the
chassis and exhaust it through vents on the right side of the chassis. For more
information, see “J2320 and J2350 Cooling System” on page 25.
On J2350 routers that comply with Network Equipment Building System (NEBS)
criteria, the air intake grid contains a filter. To verify that the system is a
NEBS-compliant system, run the show chassis hardware command. A NEBS-compliant
system displays the term NEBS in the output.
We recommend changing the filter every 6 months. However, the optimal filter
replacement interval can vary depending on the environment where the router is
located. If temperature alarms appear, inspect the air filter.
To replace the air filter:
1. Loosen the filter tray thumbscrew at the rear of the J2350 chassis.
2. Hold the screw firmly and pull it away from the chassis until you have pulled the
attached filter tray out of the chassis (see Figure 99 on page 207).

3. Hook-and-loop fasteners on the base of the filter tray hold the air filter inside
the tray. Grasp the air filter with your fingers and gently pull it away from the
filter tray.
4. Set the old air filter aside.
5. Place the new filter so that its edge aligns with the first hook-and-loop fastener
as shown Figure 100 on page 208.
