| 8 | Here are the steps to enable network connection to DDS from the |
| 9 | dcs spare (dcs2). |
| 10 | |
| 11 | 1. If the system to be replaced is still alive, login and |
| 12 | run "ifdown eth3" as root. |
| 13 | |
| 14 | 2. Log in the spare (dcs2) as root and run the command |
| 15 | "ifdown eth3". |
| 16 | |
| 17 | 3. Open the front door of the NASA rack and examine the |
| 18 | three red ethernet cables. Normally the dcs0 cable |
| 19 | should be on port 12 of switch x20b, the dcs1 cable |
| 20 | should be on port 3 of switch x20a, and the dcs2 |
| 21 | cable should be on port 4 of switch x20a. To fail- |
| 22 | over HMI, unplug the dcs1 cable and move the dcs2 |
| 23 | cable into port 3, switch x20a. To fail-over AIA, |
| 24 | unplug the dcs0 cable and move the dcs2 cable to |
| 25 | port 12, switch x20b. |
| 26 | |
| 27 | 4. Run "/etc/sysconfig/network/XXX-up", where XXX is |
| 28 | either HMI or AIA, on dcs2. |
| 29 | |
| 30 | |
| 31 | To restore the original dcs2 to itself, run "ifdown eth3", |
| 32 | move its red ethernet cable back to port 4, switch x20a, |
| 33 | and run /etc/sysconfig/network/MYSELF-up. |
| 34 | |
| 35 | To put the origina HMI or AIA machine back online, and plug |
| 36 | its red ethernet cable back in its original port (port 3, |
| 37 | switch x20a for HMI; port 12, switch x20b for AIA). If |
| 38 | the machine has not been rebooted since it went offline, |
| 39 | run "ifup eth3". |
