Hardware Description 1

The following ﬁxtures are present on the front panel of each PEM:

•A green LED that comes on to indicate that –48 VDC power is available to the chassis

•A circuit breaker

Note To turn off a Cisco 6200 that has two PEMs, you must ﬂip the circuit breakers on both

PEMs to OFF (0).

1.2.5 Cooling Vents

The cooling vents are located on the sides, front, and back of the Cisco 6200 chassis, as shown in Figure 1-4. Air ﬂows in at the bottom of the chassis, and ﬂows out at the top. Do not obstruct the intake and exhaust vents in any way.
