Hi. I have a 3Com Total Control Chasis that has several 3Com HiPer ARC NAC cards in it. I'm trying to upgrade the Software on these cards to 5.3.2. Some of these cards have: #of cards software version Hardware Version DRAM Flash 2 4.1.11 19.0.0 131072 16384 1 4.1.72 19.0.0 65536 8192 1 4.2.32 19.0.0 131072 16384 1 5.3.107 23.0.0 131072 16384 Everytime I go to update these cards using 3Com's total control Manger software v8.2.6 the update gets to about 80% then stops, says it's completed. The cards get stuck/hung up and I have to power cycle the chasis. The cards keep the same software version. Could someone tell me what I might be doing wrong. Do I have to upgrade these cards in increments? Can't I just flash-update them directly to the 5.3.2 update? Any help would be appreciated. Thanks, jim jmccay@adsnet.com
