CISCO SF112-24 (01) PDF Document

To optionally rack-mount your CISCO SF112-24, follow these steps:

Step 1. Attach one of the provided rack-mount brackets to the side of the switch using the screws that came with the unit. Ensure the bracket is securely fastened.

Step 2. Attach the second rack-mount bracket to the opposite side of the switch using the provided screws.

Step 3. With both brackets installed on the switch, position the switch in the rack and secure the brackets to the rack using appropriate screws and cage nuts (not included).

The following rack-mount safety instructions are included for the installation of your CISCO SF112-24:

A) Elevated Operating Ambient – If installed in a closed or multi-rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.

B) Reduced Air Flow – Installation of the equipment in the rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

C) Mechanical Loading – Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

D) Circuit Overloading – Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing these concerns.

E) Reliable Earthing – Reliable Earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch current (e.g. use of power strips).

To install the CISCO SF112-24, you have two options:

1. Place it on a flat surface by setting it on its four rubber pads.

2. Mount it on a wall using the wall-mount slots on the bottom panel of the switch.

To use the optional wall mount for the CISCO SF112-24, follow these steps:

Step 1: Attach two screws to the wall such that the wall-mount slots of the switch lineup with the two screws. The wall-mount slots are two criss-cross slots on the bottom panel of the switch.

Step 2: Maneuver the switch to insert the screws into the two wall-mount slots.

To power on the CISCO SF112-24, connect the supplied power cord to the power port on the back of the switch. Then, plug the other end of the power cord into a standard electrical outlet.

To attach devices such as computers, servers, printers, or wireless access points to the CISCO SF112-24, plug a standard Ethernet network cable from the device into one of the available numbered ports on the front of the switch.

The ambient temperature rating for the CISCO SF112-24 is shown in the table below:

The CISCO SF112-24 has built-in diagnostics to detect cable issues. It provides network integrity and can detect loops. For best detection accuracy, use a minimum cable length of 10 meters (~30 feet).

Cable Diagnostic Output

• A physical cable fault will cause the port’s amber LED to light up continuously.

• Loop detection will cause the port’s amber LED to blink periodically.

Procedure

STEP 1 Ensure that the switch is powered on.

STEP 2 With the suspected cable connected to the switch, look at the pertinent interface’s LED outputs. A solid amber LED indicates a cable fault or an open end. A blinking amber LED indicates a loop.
