SERVSWITCH™ AND SERVSWITCH ULTRA™

6. Separate the Serv unit’s PCB(s) and back panel from the bottom panel, being

very careful not to bend the LEDs. With the ServManager, you will have to

carefully unplug the ribbon cables of the display panel (pry gently upward)

and keypad (pry gently outward) from the J12 and J13 connectors respectively

on the ServManager’s master PCB (printed circuit board). See Figure E-5 on

page 108.

(If your Serv unit is a 2- or 4-port model, go to step 11—you don’t have to do

steps 7 through 10.)

7. Unscrew and remove the jack screws on the back panel that fasten the Serv

unit’s DB25 connectors to the panel. On 8-port units, there are 18 of these;

on 12-port units, there are 26; on 16-port units, there are 34. See Figure E-1

on the previous page.

8. Separate the PCBs from the back panel.

9. Unscrew and remove the PCB standoffs that attach the bottom (“master”)

PCB to the rest of the PCB stack. There will definitely be two of these at the

front of the master PCB; there might also be one on the narrow right-hand

end. See Figure E-1 on the previous page, Figure E-2 on the next page, and

Figure E-3 on page 105.

10. Ease the master PCB apart from the rest of the PCB stack, being very careful

not to bend the pins on the PCB-to-PCB connector J3. See Figure 3-1 on the

previous page and Figure E-3 on page 105.

11. Remove and discard the five jumpers on connector J4 in the middle of the

PCB—you won’t be needing them anymore. See Figure E-3 on page 105.

12. Two screws and two washers should have been included with your Overlay

Option Board. These might be screwed into the bottom of the Board’s two

mounting standoffs (the bottom is the end that is not attached to the Board).

If they are, unscrew and remove them.

13. Carefully plug the Overlay Option Board into J4, aligning the Board’s

mounting standoffs over the two mounting holes in the PCB. See Figure E-2

on the next page and Figure E-3 on page 105. For mini ServSwitch models,

see also Figure E-1 on the previous page; for other ServSwitch models and

ServManagers, see also Figure E-4 on page 107.
