Cooling System
The cooling system in a PTX10004 consists of two fan trays (see
Figure 7 on page
25) and two fan tray
controllers (see
Figure 8 on page
25).
The JNP10004-FAN2 fan tray contains an array of six fans and operates as a single hot-removable and
hot-insertable field-replaceable unit (FRU). The fan trays install vertically on the rear of the chassis and
provide front-to-back chassis cooling. See
"PTX10004 Cooling System and Airflow" on page
