Management
An RJ45 serial console port on the front panel of the 7520 Series switch enables you to
connect a terminal and perform local management. An RJ-45 Ethernet management
port can also be used to connect the system to an out of band management network
for administration. Alternatively, you can use an Ethernet cable to connect this port
directly to a laptop to view and locally manage the switch conguration. The Ethernet
management port supports 10/100/1000 Mbps speeds.
There is also a Type A USB 2.0 port that can host removable devices like ash drives.
Cooling
Hot-swappable fan modules that provide either front-to-back or back-to-front airow
for switch cooling are available for 7520 Series switches. The six fan slots on all models
are located on the rear panel. Switch fans are not responsible for cooling the power
supplies; power supplies have integrated cooling fans that operate independently of
the switch fan. The direction of the airow in the fans and power supplies must be the
same.
