Black Box LMC5203A, LMC5208A-R2, LMC5207A-R2 Fans, Installing Management and Application Modules

Fans

The 3-Slot Desktop Chassis includes temperature-triggered fans. When the temperature of the chassis reaches 40° C, the two fans activate to cool the chassis. The fans’ operation can be tested by holding the Alarm Reset Button down for 4 to 5 seconds. The fans will activate and then they will turn off when the button is released. If the fans do not activate, contact Black Box. Fans are not end-user replaceable.

The red Alarm Reset Button also functions as a Fan Test button. To verify fan functionality, hold the button down for several seconds, the fans should engage. The fans will turn off when the button is released.

Installing Management and Application Modules

SNMP Management Modules include two twisted pair ports, one for management and one reserved for future use. The Management Module also features a DB-9 serial port, and supports SNMP V1/V2c.

Installing Applications Modules

To install a module:

1.Remove the blank bracket (if present) covering the slot where the module will be installed. Black Box recommends installing blank brackets in unused module slots.

2.Slide the module into the chassis using the card guides.

3.Secure the module to the chassis by tightening the captive screw. (Refer to the documentation shipped with the module for configuration information.)

In order to manage a Desktop Chassis, the SNMP Management Module needs to be installed in the appropriate slot of the chassis.

• Install the 3-Slot Desktop Chassis slot SNMP Management Module into the	bottom
left slot.

NOTE

This slot is ONLY for the Management Module; do not install Application Modules such as

media conversion and mode conversion modules in this slot.
