Installing a Firmware Upgrade

In some cases the ISM’s firmware may require replacement with an updated version. There are nine user-replaceable firmware chips (figure 7-2): U1, U2, and U6 on the front panel circuit board and U98, U99, U100, U101, U102, and U103 on the main circuit board. The U-numbers are printed on the circuit boards. Extron recommends that you send the unit in to Extron for service and updates.

Figure 7-2 — ISM firmware chip locations

•Chips U1 and U2 are replaced as a pair.

•Chip U6 is replaced alone.

•Chips U98, U99, U100, and U101 are replaced as a set.

•Chips U102 and U103 are replaced as a pair.

CAUTION

Changes to firmware must be performed by authorized service personnel only. Some ISM firmware updates must be performed at the Extron factory.

Replace firmware in the ISM as follows:

To prevent electric shock, always unplug the ISM from the AC power source before opening the enclosure.

1. Open the switcher. See “Opening and Closing the Switcher” on page 7-2.

2. Locate the firmware chip(s) to be replaced on the main or front panel circuit board (figure 7-2).

3.	After you are electrically grounded, use a DIP chip
	puller to grasp each IC chip and pull it out of the	U102
	socket(s).	U102

Align notches.
