Samsung DCS Part 9Installation March 200164Part 9. Installing Keysets9.1 Installing Keyset Daughterboards (KDb)KDb DLI and SLIBefore performing this procedure, unplug the line cord from the keyset and place the keyset facedown on a soft surface. Refer to Figure 9–1.Using a screwdriver or other similar tool, carefully remove the two blanking plates from the basemoulding: one is marked EXPANSION MODULE and the other is marked EXTRA. Connect the KDb tothe keyset by pushing the pins of the KDb into the EXPANSION MODULE socket on the keyset.Now secure the KDb to the keyset base with the two screws supplied.Test the keyset to ensure normal keyset operation.Connecting to the KDbThere are two methods for connecting devices to KDbs. The simplest method is to connect the sec-ond device directly to the EXTRA socket by means of a line cord (Figures 9-2 and 9-3).Note that the KDb does not contain the ring capacitor which is required if the analogue phone or faxconnected is to ring when called. Therefore, a capacitor must be added to the circuit when the deviceis connected. This can be achieved with an adapter cable which is supplied with the KDb (Part Num-ber CA020A).The second method is to use a multi-pair station cable, connecting separate station jacks to the firsttwo pairs. A line cord can now be connected between the KDb and the second jack. This returns theKDb port to the MDF for cross-connection to another cable run (Figure 9-4).NOTE: When you have connected the line cord to the keyset, secure it in place using the supplied clamping plate andscrew (Figures 9-2 and 9-3).9.2 Wall-Mounting a KeysetDCS keysets come equipped with a reversible base wedge as standard. To wall-mount a keyset, re-move the wedge from the keyset, turn it through 180 degrees and reattach it to the keyset (Figure 9–5).Use the mounting holes to attach the base wedge to the wall.
